A friend of mine just found out that I’ve been eating a keto diet for the past few months, and they told me I should stop right away and get my selenium levels checked. They said I could be at risk of a heart attack because of keto. Now I’m freaking out a bit. Help?
Don’t freak out. Let’s look at the evidence.
First Off, What is Selenium, and Why Do We Need It?
Selenium is an essential trace element that we get from our diets. Enzymes called selenoproteins play a variety of important roles throughout the body. Notably, selenoproteins in the thyroid gland facilitate the conversion of T4 to T3.https://pubmed.ncbi.nlm.nih.gov/11848134/‘>2 This is the case with Keshan disease, a potentially fatal cardiomyopathy (disease of the heart muscle). Keshan is a region in China where the soil is depleted of selenium. As a result, residents were suffering high rates of heart disease before a supplementation program was introduced. Selenium deficiencies can also lead to male infertility because a selenoprotein known as GPx4 protects spermatozoa from oxidative stress.https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1829306‘>4 https://pubmed.ncbi.nlm.nih.gov/20031863/‘>6 Selenium supplementation doesn’t appear to prevent heart disease, but clinical trials have mostly been carried out in adult males who already get enough selenium from their diets.https://ods.od.nih.gov/factsheets/Selenium-HealthProfessional/‘>8 So already, your friend’s basic premise seems shaky, but let’s do our due diligence here and ask whether following a keto diet puts you at greater risk.
Is There Any Evidence that Keto Causes Selenium Deficiency?
Yes, specifically among children who were prescribed a therapeutic ketogenic diet to treat intractable epilepsy.
As of 2020, there were at least 66 documented cases of selenium deficiency among children on a therapeutic ketogenic diet.https://www.ncbi.nlm.nih.gov/pubmed/12681013‘>10 https://pubmed.ncbi.nlm.nih.gov/10881264/‘>12 so selenium might not have been the culprit here.
It’s unclear exactly how prevalent selenium deficiency is among pediatric epilepsy patients on keto. One study of 110 kids found that nearly half of them had low selenium. None of them showed evidence of cardiomyopathies as a result.https://pubmed.ncbi.nlm.nih.gov/21615805/‘>14 Selenium levels decreased over time, with some kids falling under the recommended range by the end.
So it’s clear that selenium deficiency is a risk for these kids. However, the current medical opinion is that nutrient deficiencies can be managed with proper monitoring and supplementation and, moreover, the risk of serious adverse events is small.
What about in Healthy Adults?
I haven’t seen any evidence that selenium deficiency is a concern among healthy adults following ketogenic diets, much less heart problems as a result.
Here’s the deal: it’s incredibly easy to get selenium in your diet, keto or otherwise. The RDA for selenium is 55 µg per day. Here is just a sampling of the selenium content of common foods:
- One 5-ounce can of tuna: 103 µg
- 4 ounces (113 grams) of coho salmon: 43 µg
- 4 ounces of skinless chicken breast: 31 µg
- 4 ounces of 80% lean ground beef: 23 µg
- 2 ounces of beef liver: 20 µg
- 1 large egg: 15.4 µg
You can see that most keto dieters will exceed the RDA without even trying. If you’re concerned, eat a Brazil nut. Yep, just one. A single Brazil nut packs 90.6 µg of selenium.
So Why Are Kids with Epilepsy at Risk?
It boils down to the specific type of keto diet they are prescribed. All the kids in the aforementioned studies were following a therapeutic ketogenic diet designed for intractable epilepsy. This diet is wildly different from a Primal keto diet, and this is the crux of the matter.
Therapeutic keto diets usually follow a 4:1 ratio, meaning that for every four grams of fat, the child gets 1 gram of carbohydrate and protein combined. In other words, they have to restrict carbs and protein enough so that together they only comprise 20 percent of their food intake. In fact, the goal is to eat the bare minimum of protein necessary, in order to drive ketone levels as high as possible. As you can imagine, this makes the diet difficult to follow. It also increases the risk of nutrient deficiencies and associated health problems. (Hence the increasing interest in “modified Atkins” diets, which might be just as effective using 2:1 or even 1:1 ratio that allows for more protein.)
The keto diet an average person follows for health, weight-loss, or longevity purposes is probably nowhere near as strict a therapeutic 4:1 diet, nor should it be. The version of keto I recommend in The Keto Reset Diet and Keto for Life contains plenty of protein and embraces a colorful variety of plant foods to cover your nutritional bases.
All in all, this isn’t something I’m worried about. Any version of a Primal keto diet that includes meat will contain plenty of selenium. To ease your mind, you can always ask your doc for a selenium test, but that seems like overkill in my book.
One last note: as with any vitamin or mineral, it’s possible to get too much selenium. Don’t go eating a cup of Brazil nuts per day because your friend has you worried. Just eat your regular, balanced diet, and you should be good to go.

With gyms closed for the foreseeable future, now is the perfect time to expand your home workout. This simple, relatively inexpensive DIY parallettes project sets you up for a wide variety of dip bar exercises. Learn how to make your own parallettes with instructions, a materials list and a follow-along video with Primal Health Coach Brian. This post also includes a breakdown of a dip bar workout for beginners to get you started.
What are Parallettes?
Parallettes or planche bars can support an impressive range of exercises, ranging from beginner to advanced. Sometimes these bars are referred to as pushup bars or calisthenics dip bars, however, those tend to be a bit longer and lower to the ground. Though often associated with gymnasts, parallettes can be invaluable tool for expanding anyone’s range of bodyweight exercises.
How to Build Parallettes
Purchasing parallettes at the equipment store can be pricey – with some options costing up to a whooping $100 a piece (and you’ll want two).
Reaping the benefits of parallettes exercises doesn’t have to break the bank. Skip the big spending and head to any hardware or home improvement store to make your own parallettes. The materials cost roughly $20-$30, and building doesn’t require any special tools. These durable and inexpensive parallettes can be made entirely from PVC pipes in just a few minutes.
What You’ll Need
Most hardware stores will be willing to cut the PVC pipes for you to your exact dimensions. Be sure to have these lengths on hand before heading to the store.
- Four 1 1/4″ T-sockets
- Four 1 1/4″ elbow sockets
- Eight 1 1/4″ end caps
In addition to the fittings, all you need to buy is one 10ft 1 1/2 inch PVC pipe. Have them cut into the following measurements:
- Eight 6-inch pieces
- Four 10-inches
- Two 14-inch pieces
Tip: Go when it’s not busy to for the best chance of someone being available to cut them for you.
How to Assemble
- Connect your two 14-inch pieces to elbow sockets.
- Attach your four 8-inch pieces to the other side of the elbow socket.
- Add a T-socket to each 8-inch piece.
- Attach a 6-inch piece to all remaining sockets.
- Place an end cap on each of the 8-inch pieces.
- Make sure each connection is secure and sturdy before beginning your workout.
After this quick assembly, you’re ready to begin your parallette bars workout.
Parallettes Bar Exercises for Beginners
Parallettes strength training uses your own body instead of weights for a Primal workout. Like any new piece of gym equipment, start with simple exercises to become comfortable before transitioning into more advanced movements. Google or YouTube videos might show the impressive feats achieved with parallette bar exercises, but before testing your limits, follow along with these dip bar exercises for beginners to become more familiar with the bars and test your strength.
Parallette Push Ups
Parallette push ups provide a greater range of motion and a deeper stretch in your chest. Keep your back flat and extend fully down, and then all the way back up. Elevate your feet on a well-secured bench for a more advanced take on the parallette push up.
There’s a few approaches to dips.
Place the bars vertically at your sides, with your feet out in front of you, and then proceed to raise up and down while fully extending your arms. You can also place the bars in front and behind you with your feet resting on the bar in front. Your body should make roughly a V-shape on the ground and then lift into an L-shape, parallel to the bars.
Band-Assisted Plank or Planche
Use a workout band to loop your feet behind you, keeping your body parallel to the floor, as you would with a normal plank position. You might find that over time you can remove the band as your strength increases.
To start off this progression, build your core strength by tucking your legs as you lift into a “sitting position” with a parrallete supporting each arm.
You can then continue the progression to supporting your lower legs with a band to achieve the “L shape.” Over time, as core strength builds, you’ll be able to remove the band and move into the “L shape” unassisted.

If you’re not sure how to express your love for your significant other, your children, close friends, parents, or other special people in your life, chocolate is a safe bet. Chocolate is the universal language of love, and a language that we’re particularly fluent in over here at Mark’s Daily Apple.
We put together six Primal, paleo, and grain-free chocolate recipes that you can enjoy with the special people in your life, with zero guilt.
Dark Chocolate Hazelnut Hearts
If you think making chocolate at home is too complicated, you’ll be surprised by how easy this recipe is. Simply melt cacao butter, then whisk in cacao powder, and avocado oil with a little sweetener, and you’ll be in chocolate heaven. What’s really fun about making chocolate at home is experimenting with all sorts of flavors. Nuts, nut butters, coconut flakes and coconut butter, spices, dried fruit … the flavor variations are endless.
This recipe is for purists, though, who like dark chocolate with just a hint of added flavor. In this case, it’s hazelnuts, which pair perfectly with chocolate.
Chocolate Peanut Butter Fat Bombs
These little fat bombs are the perfect treat and a great way to up the healthy fats in your diet while eating keto. We used Primal Kitchen® Peanut Butter Collagen here, but you can swap it out with vanilla or chocolate varieties. Store these fat bombs in the fridge or freezer to keep them firm. For a more chocolatey fat bomb, melt your favorite super dark or sugar-free chocolate and dip the tops of the chilled fat bombs in them. Dust with more Collagen Fuel and chill before enjoying.
Grain-free Fudgy Brownies
Keto eating should always put nutrients first, but there’s nothing wrong with having treat recipes on hand for when you’re making the conscious choice to enjoy something sweet. This recipe offers it all—whole food, Primal friendly ingredients for whipping up either a Primal brownie batch…or a keto version. You’ll enjoy the rich texture and deep chocolate taste without the typical sugar rush.
Tips: This recipe has a primal option sweetened with dates and a keto option sweetened with a granulated monk fruit sweetener. Feel free to use Swerve in lieu of the monk fruit. These brownies are extra fudgy and taste even better after being refrigerated, so we highly recommend allowing them to cool, cutting them and then placing them in the fridge for a few hours or overnight before enjoying.
Keto Chocolate Bacon
Why is this only a recent invention?
You likely have these two ingredients on hand in your kitchen most of the time. Very dark chocolate (90%) has a bitterness akin to coffee that enhances all of the flavors paired with it, and what better flavor spotlight than slightly sweet, salty, smoky bacon? You can guild the lily by adding toasted unsweetened coconut or finely chopped nuts to the chocolate before it sets, but we prefer this as a twosome.
Mini Chocolate Hazelnut Tarts
If you’re looking for a dessert worthy of a celebration, look no further. Rich, smooth, and decadent on the inside; crunchy and nutty on the outside. The full effect? Nothing short of fabulous. Enjoy as a “small bite” portion with coffee after dinner, or allow yourself the total indulgence of savoring the full tart.
What we love about this recipe (besides everything) is the customizable flavor. Add espresso powder or a flavored extract like vanilla, orange or peppermint for a bold as well as sweet taste.
Dark Chocolate Brazil Nut and Coconut Bars
These dark chocolate coconut and Brazil nut bars are pretty to look at, easy to make, stay fresh for weeks and are filled with healthy fats, flavanols, and selenium. What more could you possibly want from dessert?
The idea to use a silicone ice cube tray for shaping chocolate comes from this recipe for dark chocolate snack bites. Pouring warm chocolate into a small ice cube tray yields nicely shaped, nicely sized chocolate squares.
The possibilities here are endless. Any type of nut or seed, dried fruit, sea salt, spices like cinnamon or turmeric…they can all be used to embellish the flavor of dark chocolate.

If you ask the average person on the street to list “Primal emotions,” anger will be one of the first examples they offer. You understand why: It’s raw. It’s overpowering. It feels like it comes from deep down below, from somewhere instinctual. To most people, anger is the realest emotion of all because it’s so sure of itself. There’s no mistaking anger.
Though anger has a negative connotation these days, it’s there for a reason. All emotions have a purpose. If they didn’t, emotions as a physiological category wouldn’t have arisen and survived millions of years of evolution. An emotion is an adaptation to an environmental condition. Anger exists because it promotes—or promoted—a survival advantage. Those animals who felt something approximating anger outcompeted those who didn’t. That’s what it comes down to.
On the surface, anger is a self-protective adaptation. By showing anger, we display a capacity for aggressive action to those who would threaten us or our tribe—and most socially astute, reasonable people (and even many animal predators) will retreat in the majority of situations. Anger, in this way, is part of the “checks and balances” system inherent to our social contracts. It gives the other party pause to consider whether it’s really worth the trouble to encroach.
But like other emotions, anger is also an internal messenger. When we feel the rush of anger overtake us, that’s an internal signal that a line has been crossed. Maybe someone has threatened or harmed a loved one. Perhaps you’ve become aware of an injustice. And when a line has been crossed, anger is your signal to act: to defend yourself, your family, your integrity, your home, or your ideals.
Unfortunately, the line isn’t always worth defending. Sometimes we mess up and feel angry over something silly. A line has been crossed, but it was a ridiculous line that doesn’t objectively deserve the response. That’s what we need to figure out and manage: why are we angry and what can we do about it?
You certainly can’t just ignore it. The visceral energy of anger is remarkably durable. Because it’s a fact. It exists. It will come up. Lines will be breached. Most of us no longer live in the same ancestral environment where raw unfiltered anger makes obvious sense, but arise it will all the same. We kid ourselves if we think we’re immune to its inherent human force. How can we keep it reined in enough to not thwart our own well-being or run afoul of the law? How can we control or manage it—even channel it? In short, how can we have and express well-deserved anger without getting burned by it?
Tips for Managing Anger (So It Doesn’t Manage You):
Practice mindfulness, and bring that deep awareness to anger when it rises.
This isn’t about leaving society. It’s simply about being cognizant of what you’re feeling and how those feelings unfold in you. To do this, we learn to stop identifying with our feelings and come to observe them instead. Mindfulness practices can be essential here. And it doesn’t have to be as involved as an hour long meditation. Alternatives exist. The “count to ten and breathe deeply” stuff you tell kids trying to handle their anger works on adults, too.
Get back in your body while you’re at it.
Use the awareness to feel yourself become flushed in the face. Notice the blood retreat from your extremities. Sense the emotional force rising in our abdomens or pulsating in your forehead. Then breathe into those sensations, disarming each before they take off into uncontrolled rage. With practice, we can nip anger (when we deem it unproductive) in the bud by not trying to manipulate ourselves emotionally but by putting our full focus on physical “symptoms” and addressing those.
Ask if it’s really worth getting angry.
Taking a step back in the heat of the moment—or better yet before the anger actually erupts—to objectively assess the merits of your anger can make a big difference. Long commute? Sure, that’s annoying, but is it worth it to get angry? Who is it helping? What adaptive effect is the anger producing? Remember: anger is suppose to be beneficial. It’s supposed to trigger positive results, actions.
Follow the thread of your anger to determine who or what you’re really angry about. If you’re angry at your long commute, are you angry at the traffic? The other drivers? Your boss? Probably not. Maybe you’re actually angry at yourself for getting yourself into this position. See? Now we’re getting somewhere.
Or maybe you’re angry at something you saw on the news. Some politician said something, and now your day is ruined. What’s that about? What the hell are you doing to yourself? How can you avoid this kind of anger in the future? Politicians are always going to say and do infuriating stuff. What if—stay with me now—you stopped listening?
Fortify your line.
Remember how anger is an emotional reaction to a perceived breach of your line?
Our lines are porous these days. Whereas most ancient humans did meaningful work, had plenty of leisure time, slept when it got dark, ate whole natural foods, and knew nothing of what transpired the next village over, the standard baseline setting for the modern human is tons of chronic stress, not enough sleep, poor diets, too much news consumption, unfulfilling jobs, and a disrupted, discordant way of life. In many ways, our lives are harder and we are more susceptible to anger than ever before. We know more things and thus have more to be angry about, and when we get angry we are less equipped to deal with it.
Your family being threatened is one thing. That always deserves anger. There’s no getting around that. But if you find yourself blowing up over silly things on a regular basis, or everything, you need to fortify your line. Keeping your micronutrient intake up, getting regular physical activity, sleeping enough, managing your stress, taking care of business in general, limiting your news intake, finding a higher purpose or power toward which to strive—these are the baseline anti-anger interventions.
Find healthy outlets for aggression.
Modern life can keep us peaceful—or subdued, depending on how you look at it. Some folks do well with this, while others just don’t. Your quick temper might be a sign you’re not getting your thrills from the physical risk and adventure you inherently crave. It’s not wrong to feel aggression, but it should be directed in a healthy direction. Instead of picking fights with strangers in the parking lot, try martial arts, boxing lessons, or competitive sports.
Transmute your anger.
Anger is energy, unfulfilled. Directionless energy that has to go somewhere, has to express itself. If there are things in your life you aren’t taking care of, that frustration can explode outward as anger—often in response to something otherwise inconsequential or minor. Direct the simmering energy within toward a productive outlet.
Thanks for reading, everyone. How have you learned to manage your anger? What role does it play in how you operate day to day?

“Should I take a probiotic?”
Some people say probiotic supplements are the answer to whatever ails you: digestive complaints, brain fog, immune system problems—even cancer.
And then there are those who liken probiotics to multivitamins: a surefire method of creating very expensive urine—or in this case, poop.
The truth is, taking a probiotic can be worth it.
But any potential benefits depend on factors like: Who’s taking the probiotic? Under what circumstances? And for what goal?
In fact, even though I’m a coach with a PhD in this area, most of my clients don’t take probiotics.
That’s not because they don’t ever work. It’s because we only know they work in certain situations.
That’s why in this article, I’ll guide you through:
- What “gut health” actually means and how probiotics could support it
- Why we have so many unanswered questions about probiotics
- The benefits of probiotics, based on the scientific evidence
- How to choose a probiotic, when to take it, and how to tell if it’s working
- The two best things you can do to support your gut microbes, no supplements required
Ready? Let’s learn all about these little bugs.
What are probiotics?
According to the World Health Organization (WHO), probiotics are “live microorganisms, which when administered in adequate amounts, confer a health benefit on the host.”1
A simpler definition would be:
Probiotics are bacteria (and sometimes yeasts) that offer health benefits.
Probiotics come in supplement form and are also found in various fermented dairy products.
Fun fact: Based on the current evidence, fermented dairy, such as yogurt and kefir, is the only food that can be considered probiotic.
Other fermented foods like kimchi, sauerkraut, kombucha, natto, and miso may have health benefits, but aren’t probiotic because they don’t contain the types of bacteria that fit the definition above. Also, pickled foods don’t fit the definition either (sorry!), though they’re certainly delicious.
There are dozens of strains of probiotics.
They often have long names that may seem difficult to remember and even harder to spell. I’ll mention quite a few of them in this article—not to make your head hurt, but because specific health benefits depend on specific strains.
The full name of each strain includes its genus, species, subspecies (if applicable), and an alphanumeric designation that serves as an identifier.
Unless you’re a scientist, you’ll mostly hear strains referred to by just their genus and species (i.e. Lactobacillus reuteri or Bifidobacterium longum).
Occasionally, you’ll also see the specific strain included by name and/or numeric identifier.2
These distinctions can be important because, in some cases, different strains of the same genus and species have very different effects. For example, Escherichia Coli Nissle is probiotic, but Escherichia Coli Shiga (sometimes shortened to just E. Coli) is pathogenic, meaning it’ll make you sick.
To put this into real-life terms, at the genus level, we’re talking about the difference between a dog and a wolf. When we get down to the strain level, it’s like specifying between a dog and a dingo. In the chart below, you can see how the probiotic taxonomy compares to that of an animal.
Some of the most common probiotic strains come from following genera (not to confuse you more, but genera is the plural of genus):
- Saccharomyces (these ones are actually yeast!)
Lastly, some probiotic supplements contain multiple strains. Often, these are given a special product name, such as VSL#3, a multi-strain probiotic with Lactobacillus, Bifidobacteria, and one strain of Streptococcus that you’ll learn more about later in this article.
Why are probiotics a thing?
A lot of times, people hear “bacteria” and think, ‘Oh, that’s the stuff that makes you sick.’ But our bodies are actually packed with different types of bacteria and other microbes—especially our gut.
That’s what we mean when we talk about the gut microbiome, the complex ecosystem of microbes (and their genetic material) that live in our GI tract.
These microorganisms are with us when we’re born, and they do more than just freeload. When everything’s working properly, they:
- help ferment undigested nutrients to produce beneficial compounds, in some cases (those are called postbiotics)
- prevent harmful bacteria and yeast from overpowering the gut by starving them out or actually attacking them (cool, right?!)
- play a part in regulating immune responses to infections and potential allergens
- influence energy balance and potentially body composition
- may (potentially) influence mood, behavior, and cognition.
As you can see, our GI microbes have several important and wide-ranging jobs. So it’s understandable that people want to prioritize their gut health. Thus, the interest in probiotics.
But what are we actually talking about when we use the term “gut health”?
It depends on the context. But usually, when we talk about having a healthy gut, we mean:
Having a diverse gut microbiome with a wide array of different types of microbes and microbial genes.
Diversity is crucial, because it prevents one niche group of microbes from overpowering the rest of the population, which could make you sick.
It’s also important because we know our gut microbes have key metabolic and immune functions related to their genetic material. Except… we don’t totally know which microbes do what.
So a wider variety of microbes means more genes to perform a variety of functions to support our health.
When there isn’t a wide enough array in a person’s gut, it’s called dysbiosis. You might hear people saying gut dysbiosis is bad and scary, and that you need probiotics to “fix” it. You may also hear that dysbiosis causes leaky gut, also known as intestinal permeability.
(You can read more about leaky gut later in this article, but long story short: There’s no agreed-upon way to diagnose leaky gut, and it’s not something you need to worry about.)
It’s true that dysbiosis can cause problems or signal there’s a problem in your gut, and that probiotics might help. But not always. That’s because…
There’s no single “healthy” gut profile.
A healthy person’s gut profile (or the different types and amounts of microorganisms they have in their gut) could look completely different from another healthy person’s gut.
The same goes for people with various diseases: two people with the same GI disease, for example, may have vastly different gut profiles.
So while probiotics can help in certain situations (see them here), there’s still a lot we don’t know about how our gut works and what probiotics can do. And when it comes to gut health overall, I often say we’re being sold a problem so we can buy a solution.
That’s why it’s important to keep your eyes and ears open for disinformation and sales tactics related to gut health.
In particular, watch out for anyone/anything claiming that:
- gut dysbiosis, gut imbalance, or leaky gut is the cause of any disease
- they can diagnose, treat, cure, or prevent dysbiosis or leaky gut
- you need supplementation, detoxing, or any sort of “gut reset”
- they can design a specific diet for you based on the microbes in your gut
- there’s a specific profile of a “healthy” gut or dysbiosis
- they have the ability to directly modify your gut microbiota in a specific way
- studies from rodent or cell culture are directly representative of the human gut microbiome
The bottom line: There’s still so much we don’t know about the gut microbiome that it’s impossible to define “good” or “bad” gut health.
The benefits of probiotics aren’t a sure thing.
At most, we have moderate evidence that certain probiotic strains might help alleviate certain health issues.
Turns out, it’s very tricky to do research and draw conclusions on the benefits of probiotics. That’s because:
There are hundreds of known strains of gut bacteria.
And potentially hundreds or thousands more that we haven’t been able to identify yet. It’s going to take a while to sift through them all and understand their effects.
Designing high-quality research is tough.
There’s no standardization in:
- Probiotic strains
- Dosage for trials
- Treatment time
So when we look at the outcomes of different studies, they may not be comparable due to how the research was designed. That can make it difficult to draw conclusions.
Much of this research is done on animals.
These studies are useful in telling us how things might work in the gut, but we can’t extrapolate the findings to humans.
There may be some bias in which strains get studied.
Certain strains tend to come up more often in research than others. When scientists see that a certain strain seemed effective in one study, they might (consciously or unconsciously) select it for another study.
Also, some research may be funded by commercial entities (for example, a specific brand of yogurt), which affects which strains are studied.
Ultimately, this all means we have less information about some strains, and more information about others.
Response to probiotics is highly individual.
A supplement might work wonders for one person—but offer no benefit to another—due to differences in gut profiles and other factors.
What’s more, some people appear to be resistant to supplementation.
One study had a group of people take a Lactobacilli supplement.3 Then, researchers sedated each volunteer and then inserted a long, flexible tube into their intestines to see if the probiotic strains had successfully enriched their gut.
(If this sounds hauntingly like your last colonoscopy, you’d be right on.)
Researchers also asked volunteers to hand over their feces for analysis.
The results? The scientists found remnants of the probiotic in everyone’s poop. But during the colonoscopies, they discovered some participants’ guts weren’t enriched with the probiotic strains. For these people, the probiotics essentially passed right through them. So…
Finding #1 was that people responded differently to the probiotic strains.
Finding #2: Fecal counts were not a reliable measure of how well a probiotic “worked” in this study. And most studies use fecal counts as their main measure of how well a probiotic “worked.”
Which leads us to…
Measuring whether probiotics “work” is tricky.
Just because you pooped out microbes doesn’t mean they took up residence and started multiplying in your gut, as evidenced by the study mentioned above. But taking samples from a person’s gut requires, well, getting a tube stuck into your intestines. And it’s not always easy to find enough people who are willing to endure that in the name of science.
The benefits of probiotics: When is a supplement a good idea?
Check out the chart below to see the health concerns probiotics are shown to help with. After that, I’ll delve deeper into each issue individually.
One thing I need to get out of the way:
There’s no probiotic supplement that works like a multi-cooker—solving five different problems all at once.
Instead, probiotics work more like a bread maker with a persnickety on-off switch. They only do one thing, and they only do that one thing… sometimes.
Probiotic supplements are both strain-specific and population-specific. So there’s no need to pop them the way you would a multivitamin.
You have to be taking the right strain for the right job, and there has to be some evidence that the strain can actually do that job. Even then, there’s no guarantee a probiotic will help solve the problem.
So a crucial first step in deciding which probiotic to take is to ask yourself:
Why do I want to take a probiotic?
Because based on what we currently know, probiotics may help in just a few specific situations.
Taking a probiotic may be helpful if:
You’re taking antibiotics.
Antibiotics kill off some of your gut’s microbes, which can cause a form of dysbiosis. (Remember, dysbiosis is when you don’t have enough diversity in your gut.)
This type of imbalance provides opportunities for pathogenic bacteria (the nasties that make you sick) to multiply and take over. That’s why some people get diarrhea while taking antibiotics.
One example: Clostridium difficile (often called C. Diff) normally hangs out in your gut. But it doesn’t cause problems, because the rest of the microbes in your gut keep it in check. Except, when you take antibiotics, C. Diff might get the opportunity to thrive, which can make you really sick.
So if you have to take antibiotics, taking probiotics alongside them may help reduce the risk of antibiotic-associated diarrhea.4Lactobacillus rhamnosus GG and Saccharomyces boulardii seem to work best.
But you may want to wait and see if you actually get diarrhea before starting a probiotic. Why? Starting a probiotic too soon can backfire when it comes to getting your gut back to normal.
One study dug deeper into this by looking at a healthy group of people who were taking antibiotics.5
Some participants took Lactobacillus rhamnosus GG, some took the antibiotics only, and some got a transplant of their own pre-antibiotic poop after finishing their antibiotics (also known as an autologous fecal transplant).
The people who got back to their baseline fastest? The ones who got the fecal transplant, followed by the ones who took the antibiotic alone.
In last place: the group that took a probiotic.
The researchers theorized that the probiotic overpowered the participants’ native microbes, making it take longer to recover.
The takeaway? Since getting an autologous fecal transplant isn’t an option (they’re not FDA-approved for this purpose and, well, they’re a little inconvenient), the next best things are:
- Do nothing, and only use a probiotic if you get antibiotic-associated diarrhea
- Take Saccharomyces boulardii along with your antibiotic, which has been shown to help, but doesn’t seem to have the same overpowering effect as Lactobacilli strains.
You have infectious diarrhea.
Got a stomach bug that’s causing diarrhea or traveler’s diarrhea? Taking Lactobacillus rhamnosus GG or Saccharomyces boulardii might help.
There are differences between what works best depending on the cause of diarrhea, as well. For instance, Lactobacillus rhamnosus GG seems to work better for diarrhea associated with C. Diff infections than it does for general infectious diarrhea.6 If you’re not sure which to try, consult your doctor or pharmacist for their advice.
You have irritable bowel syndrome (IBS).
Bifidobacterium and Lactobacillus probiotics appear effective for reducing symptom severity in people with IBS.7,8,9
Caveat: Because some of the research uses quality of life scores and most of the strains seem to offer the same effect, there may be a placebo effect at play.
Still, if you have IBS, it may be worth it to give probiotics a try. Some research suggests taking a single strain on a short-term basis (8 weeks) is most helpful.10 Other research notes that a combination of Bifido and Lactobacillus works best, particularly if constipation is a problem.11 (Remember how I mentioned it’s tough to draw conclusions from probiotics research? This is a good example of that.)
So if you’re thinking of taking a probiotic for IBS, consider checking in with your gastroenterologist or a registered dietitian experienced with GI disorders about which strains to try.
You have ulcerative colitis.
Ulcerative colitis, a form of irritable bowel disease, may respond well to certain probiotic strains.
In particular, VSL#3, which is a combination of several different strains, may induce remission and prevent flares. Unfortunately, researchers haven’t seen the same consistency in treating people with Crohn’s disease.
You’re being treated for an H. pylori infection.
Heliobacter pylori is a type of bacteria that can live in your digestive tract and cause ulcers. Certain strains (Lactobacillus reuteri, Lactobacillus rhamnosus, and Saccharomyces boulardii) may have a synergistic effect with conventional treatment. And if you’re being treated with antibiotics, it could reduce any associated diarrhea.12
You want to reduce your cholesterol/improve heart health.
File this one under: Probiotics might help, but certainly shouldn’t be the primary thing you do to improve your cardiometabolic health.
Some evidence indicates that certain strains can improve lipid profiles, meaning we see reductions and either total or LDL cholesterol, as well as improved insulin sensitivity.13,14 In the case of cholesterol, the findings were specific to fermented dairy (think: yogurt) rather than a supplement.
Before you read on…
I’m about to tell you about a bunch of situations when taking a probiotic isn’t going to help.
You might respond to some of these by thinking something like:
“But I saw a study/article/documentary saying probiotics help with [fill in the blank]!”
That’s great! This is an exciting and emerging area of research, and we’re learning new things about probiotics every day.
But scientists don’t consider one or even a few studies showing a positive effect to be high-quality evidence. In order to draw a conclusion, a given effect needs to be repeated in several studies, and ideally reviewed and analyzed in a systematic review or meta-analysis.
So, for the health situations below, this may mean that:
- There hasn’t been research on probiotics and this health issue.
- There has been research, but not enough to draw a conclusion.
- There has been research, but the effects observed are inconsistent, negative, or non-existent.
We may eventually discover that probiotics DO help with some of these health concerns. But at the moment, there’s not enough evidence for health professionals to make recommendations they can stand behind.
Phew. [Deep breath.]
Probiotics are unlikely to help if:
You’re dealing with depression, anxiety, or another mental health concern.
Yes, the gut-brain axis is a thing. But we still have a lot to learn about it.
Much of the mainstream discussion around using probiotics for mental health revolves around the idea that if your gut produces more serotonin (sometimes called the “happy hormone”), you’ll have better mental health.
While it’s true that 95 percent of your body’s serotonin is produced outside the brain (including in the gut), this isn’t the exact same serotonin that makes you feel happy.15
Serotonin produced in the gut doesn’t cross the blood-brain barrier, meaning it won’t impact your mood.
Why am I pointing this out? The science simply doesn’t support the idea that having more serotonin in your gut means you’ll have better mental health. And overall, the evidence for using probiotics to help treat the following mental health issues is weak:16
- Depression: It looks like probiotics might have an antidepressant effect, but there’s not enough evidence to say that definitively.17
- Anxiety: Preclinical studies in rodents show a benefit, but, so far, these benefits haven’t been observed in humans.
- Mood: In general, it seems probiotics may have an effect on mood. But researchers are careful to note that at the moment, we don’t know enough to make recommendations.18
Probiotics should never be used in place of traditional mental health treatments. (Seriously.)
And even if you’re considering probiotics as something to try alongside therapy or medication, it’s probably not worth it.
Autism and probiotics: Can they help?
People with autism tend to report a range of GI symptoms, such as abdominal pain, diarrhea, and constipation.
This leads some experts to wonder:
Is an imbalance in gut flora to blame?
Unfortunately, we still have more questions than answers. In several studies that included people with autism, GI and behavioral symptoms sometimes worsened while they were taking probiotics.19
There’s also been lots of buzz about the promise of fecal microbiota transplantation (FMT) in people with autism. (You can read more about FMTs below!)
One study did show behavioral symptoms improved over time when people with autism received FMTs, but there was no control group, or a group of people who didn’t receive FMT treatments.20
So while the findings seem promising, it’s impossible to say whether improvement could be attributed to FMTs without a control group.
You want to lose weight.
It’d be so nice if probiotics could help us lose fat. Unfortunately, there’s no compelling evidence that probiotics can help with fat loss. Some studies have shown a reduction in waist circumference or BMI, but the effects are too inconsistent to draw conclusions.21
You have a rash or acne.
As of now, probiotics are not recommended for eczema, atopic dermatitis, acne or any other skin complaint.22,23
You have GERD.
For those experiencing discomfort related to gastroesophageal reflux disease, probiotics may seem like a nice alternative to conventional medications. Unfortunately, while some early study results have seemed promising, they’ve been inconsistent. So there’s not enough evidence to show that probiotics can help in this situation.24
You have occasional gas or other digestive issues.
If you’re wondering if probiotics can help with intermittent gas or stomach upset, the answer is no. Research shows probiotics don’t help with indigestion that has no specific, diagnosable cause.25
You’re concerned you have a leaky gut.
Though intestinal permeability, aka “leaky gut,” has been associated with various diseases and certain medications, it’s not something that can be diagnosed as a health problem (despite what Instagram “experts” may say).
When a person does have intestinal permeability, they won’t have any outward symptoms of that issue specifically—though it’s possible they may have other digestive complaints.
And regardless of whether you believe leaky gut is a “thing,” there’s no evidence probiotic supplements help repair the gut lining in people with intestinal permeability.
You have a yeast infection or recurring UTIs.
People often look for natural alternatives to treating these issues, but probiotics are unfortunately not proven to help with yeast infections or prevent recurring urinary tract infections.26,27
You want to be the healthiest person on your block.
You’re better off making lifestyle changes to support your overall health than taking a probiotic.
You want to “boost” your immune system.
We know that probiotics can play a role in enhancing immunity in certain specific situations.
For example, when you take a probiotic to help with infectious diarrhea, that’s a function of immunity. And one study showed probiotics might reduce the severity of upper respiratory tract infections in athletes.28
That said, for overall immune health—something a lot of people are interested in now given the pandemic—there are quite a few other changes you can make that will have a greater impact. (To learn what they are, check out this infographic on how to optimize your immunity.)
Fecal transplants: Are they evidence that probiotics work?
Sometimes, people cite the success of fecal transplants as evidence that probiotics work.
But what is a fecal transplant, exactly? The technical term is fecal microbiota transplantation (FMT). Basically, a healthy person’s stool is mixed with saline and then inserted into the patient’s colon.
So yes, we’re talking about poop transplants here.
We don’t know exactly how or why FMTs work, but they’ve been shown to be 80-90 percent effective in helping people with C. Diff infections that don’t respond to other methods of treatment.29
It’s thought that FMTs might help these patients by repopulating their gut with microbes that edge out C. Diff.
These results made scientists wonder about their other potential applications: In people with Crohn’s disease, ulcerative colitis, autism, obesity, and more.
Despite great hopes for FMTs, results have been mixed in trials using them in patients with Crohn’s disease and ulcerative colitis.30 And in trials with people with obesity, no effects were observed on body weight or composition.31,32
At the moment, fecal transplants are only approved by the FDA for treating C. Diff after other treatments haven’t worked.
And does the success of FMTs underscore the effectiveness of probiotics? Not really.
Probiotics contain a much smaller number of strains and a much lower total microbial content than FMT preparations.
So essentially, just because FMTs seem to work in people with C. diff does not necessarily mean everyone should be taking probiotics.
Taking a probiotic 101: The most common questions, answered
Question #1: How do I choose a probiotic?
You’ll need to consider several factors.
Factor #1: Species, strain, or multi-strain probiotic
The species or strain(s) that will make the most sense for you depends on the reason you’re taking a probiotic. Refer to the chart above to see which specific probiotics are relevant for you.
Factor #2: Price
In most cases, taking a probiotic is a short-term thing, so price may not be a huge factor. But if it’s something you’d need or want to take long term, consider: Is the financial commitment reasonable for you?
And could you get the same benefit from lower cost (and potentially free) interventions, such as eating more whole foods and fewer highly-processed ones? (Learn more: The 5 principles of good nutrition.)
Factor #3: Dosage
We know that the effective dose for all probiotics is somewhere between 106 to 109 colony-forming units (CFUs). (FYI, those little numbers mean ‘10 to the sixth power’ and ‘10 to the ninth power. Or simply: 1 million to 1 billion CFUs).
Look for probiotics that deliver this dose in one or two administrations per day.
Also: Be sure to take probiotics before their expiration date. If you take them afterwards, you may not get the number of CFUs on the label.
And… that’s it. Don’t worry about whether your product is refrigerated. (Turns out, that doesn’t matter.)
When it comes to third-party quality certifications, these aren’t as important as they might be for protein powders and other supplements. But if you’re an athlete and want to be extra safe, it’s not a bad idea to look for a probiotic certified by NSF or USP.
The most important thing is matching up the right strains with the right health problem.
Question #2: When should I take my probiotic?
It’s best practice to take probiotics right before a meal, which seems to increase the odds of the little bugs doing their job in your digestive tract.33
If you’re on antibiotics, it’s natural to wonder if the antibiotic will wipe out the probiotic. After all, antibiotics kill bacteria, right?
The short answer: You don’t really need to worry about this; your probiotic will be fine. (And if you’re concerned, you could ask your doctor or pharmacist about antibiotic and probiotic timing.)
The long answer: Antibiotics do kill bacteria. But they work in different ways.
Some antibiotics disrupt the cell wall or membrane of the bacteria they target, others prevent protein synthesis so the bacteria die off, and others damage the bacteria’s genetic material.
Because of this, antibiotics don’t kill all the bacteria they come into contact with, so they may or may not affect the probiotics you take. And they may or may not affect your native microbiome.
Also, some probiotics are yeasts, like Saccharomyces boulardii, so they’re not affected by antibiotics.
(And to be honest, as an expert in this field, I’m less concerned about antibiotics throwing our native microbiomes off-kilter than I am about bacteria in our guts developing antibiotic-resistant genes. This is caused by antibiotic abuse or misuse, and can cause antibiotics to stop working when we really need them. But that’s another topic entirely…)
There’s also this: No matter when you take your probiotic and antibiotic, they’re both going to be hanging around in your GI tract for about a day.
That means to some degree, everything is going to get mixed together anyway, which is why this really isn’t something to be concerned about.
Quick question: Can probiotics survive stomach acid?
Yes, they can.
Most probiotic capsules are coated in a way that prevents stomach acid from getting to them. Once they reach the small intestine, the coating is dissolved.
There are even some types of Lactobacilli that live in the stomach. So the idea that stomach acid kills all probiotic strains isn’t quite right.
Question #3: How long will it take a probiotic to work?
There’s no standardization in how long you should take probiotics.
If you’re taking probiotics for antibiotic-associated diarrhea, you’ll want to take them until you’re feeling better. This could be anywhere from one to eight weeks, for instance. But if you don’t notice any improvement in your symptoms after a month, it may not be worth continuing.
If you’re taking probiotics for IBS, some research suggests people do better when they take them for shorter periods of time, as in less than eight weeks.
As a general rule of thumb, I’d recommend taking a probiotic for a month. Then, use the steps directly below to determine whether it’s working for you.
This works out conveniently, since most probiotics are packaged in a one-month supply. That way, you can make a decision about whether to continue before you buy more.
Question #4: What are the signs your probiotic is working?
To answer this question, you want to be really clear on what you hope to achieve by taking a probiotic.
Let’s say you’re hoping for improvement in your IBS symptoms.
You’ll want to set up a little self-experiment to evaluate whether probiotics are helping or not.
So start by asking: What would “improvement” look like?
Maybe it’s that you’re able to get through an entire day at work without digestive discomfort.
Or a week without having to miss out on something you wanted to do because of your IBS.
Or it could be more specific: less diarrhea, constipation, or stomach cramps.
Whatever parameters you decide on, the next step is to get in touch with your inner scientist. (We’ve all got one lurking in there!)
Collect your data. Grab a journal or keep notes in your phone, and track any changes you notice.
You might keep track of data points like your daily symptoms (or lack of symptoms) and/or your bowel movements and their qualities (using the examples in this handy visual guide to poop health).
Every two weeks, reevaluate. How are things measuring up against the metrics you decided on?
Over time, you’ll see a trend. Either the probiotics are helping, or they’re not. And from there, you can decide on your next move.
Question #5: Are there any side effects?
Probiotics can sometimes worsen GI symptoms. It’s pretty uncommon, but they can occasionally cause bloating or diarrhea.
It’s also important to be aware of potential drug interactions. For instance, people on oral chemotherapy drugs should check with their doctor before taking probiotics.
(And really, if you’re on any prescription medication, it’s a good idea to check with your doctor before starting a new supplement.)
Lastly, in people who are extremely immunocompromised, there’s the potential for bacterial or fungal translocation.
That basically means if you have a big ulcer, it may be big enough for bacteria or yeast from probiotics to pass through and get into the bloodstream. And that would cause a total body infection, which is really dangerous.
Of course, this is a rare complication but worth noting for people with a compromised immune system.
How to support a healthy gut without supplements
If you came to this article wanting to ensure you’re looking after your gut health, this section is for you.
When people ask me if they should take a probiotic or if there’s anything in particular they can do for better gut health, there are two big questions I want to answer:
- Are they getting enough fiber from a variety of sources?
- Are they getting enough physical activity on a regular basis?
I ask these questions because these are the two biggest factors that seem to determine microbial diversity.
So if you’re interested in taking probiotics for general health or for one of the issues listed in the “probiotics are not likely to help” category, you’ll want to be sure you’re implementing these two lifestyle changes first.
Not only are they often less expensive than probiotics, but they’re more likely to improve your health overall. Also, if you’re taking probiotics for purpose there’s good evidence for, these practices will be supportive.
Lifestyle change #1: Eat a nutrient-dense diet with enough fiber from a variety of sources.
If you want to support a diverse microbiome, this is probably the most important thing you can do.
Eating a wide variety of fiber-rich foods like fruits and vegetables, whole grains, legumes, nuts, and seeds is your best bet. Add in some lean proteins and healthy fats and you’ve ticked the nutrient-dense box, too.
This whole fiber thing is really important.
One probiotic study done on healthy bodybuilders looked at the group’s gut profiles.34
Though it wasn’t the main aim of the study, the researchers noticed that bodybuilders who didn’t get enough fiber had microbiomes similar to people who were sedentary.
In other words, they weren’t getting the microbiome benefits of exercise (more on that in a sec), possibly because they weren’t eating enough fiber.
What are prebiotics?
You may have heard that you should be eating prebiotics, a form of fiber that “feeds” the microbes in your gut. If you regularly eat fiber-rich foods like the ones mentioned above, you’re getting enough prebiotics in your diet. We don’t know which microbes prefer which types of fiber yet, so eating a wide array of different fiber sources is the best approach.
What about probiotic foods?
Probiotic foods may also be worth including in your diet. They’re associated with a host of beneficial health outcomes, such as a lowered risk of cardiovascular disease.13
And just a reminder: The only food that’s classified as probiotic right now is fermented dairy. This includes fermented yogurts and kefir.
What happens if a fiber-rich diet causes GI issues?
Sometimes, people eating a whole-food, fiber-rich diet experience bloating, diarrhea, and other digestive symptoms. This can be confusing, especially if you’re putting a lot of effort into eating well for health reasons.
In this situation, people often wonder if there’s something wrong with their gut health or if they need to take a probiotic.
The answer: probably not.
The bacteria in your gut ferment some of the fiber you consume. As they do so, they produce gas. That’s not a sign of poor gut health. It’s just a natural response to eating more fiber.
But if eating more fiber-rich foods causes noticeable and sustained GI symptoms, it’s a good idea to check in with your doctor.
If you get a clean bill of health or if your doctor has ruled out everything except IBS, the next step would be to start a personalized FODMAP elimination and reintroduction diet with the help of a specially-trained nutritionist or dietitian.
(To learn more about FODMAPs, and for everything you’d ever want to know about doing an elimination diet check out Precision Nutrition’s FREE downloadable e-book, The Ultimate Guide to Elimination Diets.)
Lifestyle change #2: Incorporate movement on a regular basis.
In general, exercise is a good thing for your microbiome. Active people tend to have more microbial diversity, research shows.35 So commiting to a regular movement routine is a great next step for gut health.
But there is a sort of ‘Goldilocks effect’ with exercise.
For instance, endurance exercise is associated with something called exercise-induced gastrointestinal syndrome, and people with IBS may notice discomfort with intense exercise.
So like anything else, you need to find the right balance that works for you.
Focus on physical activity that:
- you actually enjoy
- you can do regularly (i.e. several days a week)
- makes you feel good and energized, not drained or sick.
Extra credit: Focus on deep health.
If you’ve already got your fiber and exercise habits down, that’s great news. Wondering what else you can do?
There’s a lot of talk about the impact of sleep, stress, and other factors on gut health, but we don’t have much in the way of human data on how they impact microbial diversity.
How does alcohol impact gut health?
We know too much alcohol can be detrimental to gut health.
But interestingly, moderate red wine consumption seems to be associated with greater microbial diversity, possibly due to the polyphenols in wine.36
And actually, these effects are more realistic than the resveratrol buzz we always hear about red wine, because all polyphenols seem to interact with our microbiota.
So I’d recommend drinking rarely, or in moderation of red wine specifically.
(Wondering if you’d be healthier if you quit drinking? Find out in this article on the real tradeoffs of alcohol consumption.)
So as a next step for people who have the two main lifestyle changes down, I recommend focusing on practices that support your deep health, or your overall health.
These can also help you make intentional decisions about what you eat and how you move, bringing it all full circle.
What do those practices look like? Some places to start include:
- Managing stress
- Getting enough sleep
- Taking care of your emotional and mental health
- Seeking connection through meaningful relationships
- Shaping your environment to support your health and wellbeing
This might seem a little anticlimactic if you’re really charged up about getting better gut health.
I get it. The microbiome is a fascinating area of research. But in the scheme of things, we have very little in the way of practically-applicable data.
While we wait for more evidence, we do know this: The behaviors that are associated with many other positive health outcomes may also be beneficial to our microbes.
That’s actually good news, because it means in most cases, we don’t need fancy, expensive supplements for a better microbiome.
So the stuff that’s good for your overall health? It’s probably also good for your gut.
