For the vast majority of human history (and prehistory), men, women, and children had near-constant contact with the natural world around them. They were walking on the ground. They were playing in the dirt. They were digging for roots and grubs. They were eating with their hands. They were field dressing animals and wiping their hands on the grass. Nothing was sterilized; the tools to sterilize the environment didn’t exist. You could boil water, but that was about it. Bacteria were everywhere, and humans were constantly ingesting it. Even as babies, preindustrial infants nursed for almost four years, so they were getting a steady source of breastmilk-based probiotic bacteria for a good portion of their early lives.

The Agricultural Age: Farms and Fermented Foods

After agriculture and animal husbandry hit the scene, human diets changed, but their environmental exposures didn’t so much. Every day they interacted closely with the soil and/or animals (and their respective bacteria). And they also continued ingesting probiotic bacteria on a regular basis through the use of fermented food—for at least the last 10,000 years. Honey into mead, grains into beer, fruit into wine, alcohol into vinegar.

We know that fermented dairy has been an integral part of any traditional dairy-eating culture because fermentation is the natural result of having milk around without refrigeration. You take raw milk and leave it out for a couple days at room temperature, and it will begin to separate and ferment. Introduce an animal stomach and you can make cheese. Introduce specific strains of bacteria, and you can make yogurt or kefir. But the point is that dairy fermentation—and, thus, the consumption of dairy-based probiotics—was unavoidable in pre-industrial dairy-eating societies.

In areas without (and some with) dairy consumption, they fermented plants. Kimchi, sauerkraut, pickles, chutneys, soy sauce, miso, and natto are just several examples among hundreds.

Modern Diets, Modern Environments

Here’s my point to all this: probiotics in one form or another have been a constant input in the human experience… until today.

Today? We live sterilized lives.

  • We wipe everything down with anti-microbial agents.
  • We wash all our plates and eating utensils with ultra-hot water and powerful soaps.
  • We wear shoes.
  • We don’t touch (or see) dirt for days, weeks at a time.
  • We stay indoors most of the day.
  • We pasteurize our dairy. We render shelf-stable (and thus inert) our sauerkraut and pickles.
  • We sterilize our water.
  • We take antibiotics.
  • We eat processed, refined food that’s been treated with preservatives and anti-microbial additives designed to remove all traces of bacteria.
  • We employ tens of thousands of scientists, bureaucrats, and agents whose primary role is to ensure our food supply is as sterile as possible.

I get all that. There are good reasons for doing all these things, and on the balance I’d of course rather have clean water, clean food, and antibiotics than not, but there are also drawbacks and unintended consequences. We live in a sterile world, and our guts weren’t built for a sterile world. They’re meant to house a diverse array of bacteria.

What Are the Consequences Of Living a Sterile Life?

Hippocrates, the father of medicine, said that “all diseases originate in the gut.” The most obvious example, digestive issues, are some of the most common in the post-industrial world. Constipation, diarrhea, bloating, and general digestive distress affect tens of millions. Food intolerances and allergies, which also have a link to gut health, are rising.

Even conditions that aren’t intuitively linked to gut health, like autism or hay fever or even heart disease, may actually have a connection with the state of our guts or digestion.

At least since Biblical times (and probably earlier), humans have identified a connection between the gut and our emotions. “I’ve got a gut feeling…” or “I feel it in my gut.” Though it’s usually portrayed as “merely metaphor,” this connection isn’t spurious and can feel quite real. Remember when you held hands with that pretty girl or handsome guy for the first time? You felt those butterflies in your gut. Or how you had to rush to the bathroom before giving that big talk in front of your college class? You felt the nervousness and anxiety in your gut.

Evidence is accumulating that our gut bacteria can manufacture and synthesize neurotransmitters like serotonin and GABA, and even sex hormones like testosterone. We’ve even identified a legitimate physiological pathway running from the gut to the brain and back again. Couple that with the fact that gut health seems to play a role in depression, anxiety, and other related conditions, and it starts looking like our lack of exposure to probiotic bacteria could be triggering (or at least exacerbating) the rise in mental health issues.

Supporting Our Guts In the Age of Sterility

The foundation of gut health has to be diet: 1) Eating fermented foods to provide probiotic bacteria and 2) eating plant and animal foods that provide prebiotic substrate to feed and nourish those bacteria. That’s been the way of humans for tens of thousands of years—from ingesting soil-based and animal-based bacteria on the food we ate as foragers to directly producing and consuming fermented food—and it should remain the primary mode of probiotic procurement.

But there’s also a place for probiotic supplementation. Food alone probably can’t atone for the sterile existence we’ve built for ourselves. Food alone can’t counteract the several years of breastfeeding you didn’t get, the dirt you didn’t play with, the antelope colons you didn’t handle with bare hands, the untreated water you didn’t drink. You may get it now, but what about ten years ago? What about when you were a kid?

Evolutionarily novel circumstances often require evolutionarily novel responses to restore balance.

And probiotics aren’t even that “novel.” We’re clearly designed to consume probiotics in the food we eat, and probiotic supplements utilize the same ingestion pathway, especially if you consume them with food. The dosages may sound high. Primal Probiotics, the one I make (and take), contains 5 billion colony forming units (cfu, a measure of bacteria that are able to survive digestion and establish colonies in the gut) of good bacteria per dose—but that’s right in line with (or even well under) the dose of probiotics found in common fermented foods.

A single milliliter of kefir can have up to 10 billion cfu.

A cup of yogurt can contain up to 500 billion cfu.

A tablespoon of sauerkraut juice can contain 1.5 trillion cfu. Kimchi is probably quite similar.

A single gram of soil can contain almost 10 trillion cfu. A gram of soil is easy to consume if you’re eating foods (and drink water) directly from the earth.

Now, Primal Probiotics isn’t the only option. It may not even be the best option if you have specific conditions that other strains are particularly adept at addressing. (I’ll cover this in a future post.) But the way I designed Primal Probiotics was to be a good general, all-purpose probiotic with particular applications for Primal, keto, and other ancestrally-minded people living their modern lives.

For instance, one of my favorite strains I’ve included is Bacillus subtilis, the very same bacterial strain that’s found in natto, the traditional Japanese fermented soybean. B. subtilis addresses many of the issues we face in the modern world. It helps break down phytase in the gut and turn it into inositol, an important nutrient for brain and mood and stress. It helps convert vitamin K1 (from plants) into vitamin K2 (the more potent animal form of the vitamin). It can even hydrolyze wheat and dairy proteins to make them less allergenic.

There’s also Bacillus clausii, an integral modulator of the innate immune system (PDF)—the part of the immune system that fights off pathogens, toxins, and other invading offenders. Innate immunity is ancient immunity; it’s the same system employed by lower organisms like animals, plants, fungi, and bacteria. It’s the foundation of what we know as the immune response. What’s funny is that B. clausii has such a powerful effect on our innate immunity that one could argue B. clausii is an innate aspect of our gut community.

I’ve also included a small amount of prebiotic substrates in the latest iteration. I use raw potato starch (for resistant starch) and a blend of fructooligosaccharides and galactooligosaccharides. The prebiotic doses are low enough that they shouldn’t exacerbate any gut problems or FODMAPs intolerances and high enough to provide enough food for the probiotics to flourish.

Again, you don’t have to take Primal Probiotics. It’s my opinion that they provide the perfect combination of strains for most people’s needs, especially when combined with regular intakes of fermented veggies like sauerkraut and fermented dairy like yogurt, cheese, and kefir, but the actual strains themselves aren’t proprietary. You can find them elsewhere if you want to get individual probiotics. Hell, you may not even need a probiotic supplement. Depending on your personal health background, the level of sterility in your life history and current life (if you grew up on a farm drinking raw milk, for example), and the amount of fermented foods you currently consume, you may not need supplemental assistance.

But it’s sure nice to have around.

Anyway, that’s it for today.

How do you get your probiotics? Do you find them necessary for optimum health? What kind of benefits have you experienced from taking probiotics, either via food or supplementation?

Thanks for reading, everyone. Take care.

For today’s edition of Dear Mark, I’m answering questions about vitamin K2 and microworkouts. The last two posts on both topics garnered a number of good questions. What’s the best dose of vitamin K2? Should statin users taking vitamin K2, since statins inhibit vitamin K2 activity and production? Can vitamin K2 prevent or reverse arterial calcification? Is butter an adequate source of vitamin K2? What about vitamin D—does it synergize with vitamin K2? Regarding microworkouts, what if you can only do a couple pull-ups at once? Should you alternate muscle groups when doing microworkouts? Can microworkouts work with normal gym workouts? How does one do microworkouts in an office?

Let’s find out:

What’s the recommended dose of vitamin K2?

There’s no official RDA for vitamin K2. For vitamin K in general, it’s 0.09 mg. As some of the commenters have alluded, very few medical professionals have vitamin K2 on their radar. I wonder if the RDA is sufficient.

Up to 45 mg per day of MK4 has been shown to be safe and well-tolerated in women, though I don’t think that much is necessary. Some use close to that much when dealing with osteoporosis, arterial calcification, or dental issues, although the reports are all anecdotal.

Many take 1 mg of vitamin K2 as “maintenance.” I’d be comfortable taking that (and sometimes do).

I put 0.08 mg of K2 (MK7) in my Master Formula supplement. Women who are pregnant and those who take anticoagulant medications should talk to their doctor before taking more than the RDA.

So, would taking K2 make statins safer? Do you think you could take enough K2 to prevent clogged arteries or reverse clogged arteries?

I imagine they would, much like taking CoQ10 (another compound whose synthesis statins inhibit) during statin therapy can reduce statin side effects and lower inflammation. Can’t hurt to try.

As for clogged arteries, it can definitely reduce the risk of arterial calcification (by putting calcium where it belongs and not where it doesn’t). Reversal? There aren’t any studies in humans, but vitamin K2 MK4 has been shown to reverse clogged arteries in rats.

Do you have a source on muscle meat (of any type) having Vitamin K?

From this study.

I had read of recommendations of cod liver oil along w K2 which was obtained with grass fed butter. Would grass fed butter be a good source in your opinion

It’s possible, but the sources I’ve read show that majority of butter is very low in vitamin K2. Still, Weston Price swore by concentrated butter oil from grass-fed cows as a source of vitamin K2. You can still buy butter oil if you want to go that route (though you won’t get any solid data on vitamin K2 content).

I wouldn’t rely on straight butter for your vitamin K2.

Isn’t it important to take K2 when supplementing with oral D3? I’ve been seeing liquid D3 preparations with K2/MK7 added.

Yes. Vitamin D3 helps us absorb dietary calcium, and vitamin K2 helps us utilize the calcium in the right way.

What if you can only do 2-3 pull-ups to begin with? ?

That’s the perfect place to start.

Do a single pullup every time you pass the pullup bar (or branch, ledge, gym rings, etc). That’s it. One clean pullup. Don’t struggle. Don’t strain. It should feel easy. Do that single pullup every time you pass the bar. Then, when you feel ready, try doing two each time. And then three.

Suddenly, your max pullups will have doubled.

Should you alternate microworkouts by muscle group each day as with traditional strength training or can you do microworkouts covering all muscle groups each day?

You could, but I find that microworkouts give enough rest that you can work the same muscle on consecutive days. It really depends on the intensity though. If your idea of a microworkout is a 20 rep set of breathing squats with your own bodyweight on the bar, and you do that a few times a day, I would not advise doing it every day.

I don’t claim that microworkouts in this manner will optimize your muscle hypertrophy. I do claim that they’ll keep your days active, keep you healthy, keep you mobile, and get you strong.

I love the idea that any exercise is better than none at all. But I wonder if this style of workout would interfere with recovery from other more regular/scheduled workouts (weightlifting, etc…)?

On the contrary, I find that microworkouts prepare me for the more concerted, formal efforts in the gym.

My buddy Angelo Delacruz is an example of a guy who’s “always on” because he’s always doing little movements throughout the day: dancing to the music playing at the gym, busting out a quick little stretch routine, doing some clapping pushups, breakdancing. He’ll just launch into a set of heavy snatches or clean and jerks without warming up because his joints are all lubed up from the frequent microworkouts.

Well I stand at my computer most of the day 6a-2p with several sets of stairs during that time–I duck into an empty meeting room to run off 15-20 pushups a few times a day, and at lunch a few days a week ( i usually IF til 3-4p ) I do some heavy weights at the local gym for about 20 minutes or so–then comes the yard work on occasion and would you count shopping with the wife at a Big Box store as a micro workout? So How an I doing? I know Mark, Just keep moving!

You’re doing great. I see nothing to add.

As for shopping, sure, why not? Shopping can work.

I’ve been known to curl the groceries as I walk out to the car. Overhead press the cases of mineral water. Plant my feet and do cable crosses with a heavy shopping cart. Sure used to embarrass my kids.

It gets more difficult when on-site for a client. Most offices here aren’t air conditioned, so when it’s warm you’re really going to sweat which makes you less presentable. I try to make it up by picking a hotel in walking distance (~45-60min ish). If there isn’t a private space to knock out a couple of body weight exercises there isn’t a lot you can do without becoming the resident office weirdo. Maybe someone has an idea?

I wrote a post years ago about training in the office without becoming the resident weirdo. See if any of these suggestions work for you. Things are probably different when you’re in someone else’s office.

Walking meetings come to mind. Stair stuff—sprints, jumps, or simply just walking all the flights in one fell swoop. Doing as many squats as possible in the elevator before someone else enters and looks at you funny. Pushups in the bathroom stall.

Okay, maybe not that last one.

The AC thing would make it difficult, though. I can see that.

This is it for today, folks. Take care, be well, and ask any other questions you have down below!

For today’s edition of Dear Mark, I’ll be answering your CBD questions from the past few weeks. CBD, or cannabidiol, is exploding in popularity, but there are many unknowns. People have a lot of questions and there aren’t many definitive or comprehensive guides, so today I’ll do my best to make sense of it. We’re all piecing things together based on limited data—which, I suppose, is the fundamental human experience.

Let’s go:

What’s the difference between hemp and CBD?

Hemp is a (recently legalized) industrial form of cannabis used in the production of paper, textiles, clothing, biodegradable plastics, and overpriced Bob Marley shirts sold along Venice Beach. Hemp seed can be eaten (and is a fantastic source of magnesium, one of the best). Hemp is the plant.

CBD is cannabidiol, a non-psychoactive cannabinoid found in both hemp and cannabis. Unlike THC, CBD won’t get you high.

Due to legal issues, most big name online retailers won’t allow sellers to list “CBD oil” or “CBD” products, let alone CBD content. Descriptions like “full spectrum hemp extract” often mean CBD is present in the hemp oil, but it’s tough to know exactly how much. I recommend investigating the product, searching for the company that makes it, and seeing if they give more explicit details on their website. Even then, make sure the company is the actual seller on Amazon or else you may end up with a counterfeit product sold by wholesalers.

The best bet is to buy directly from the product website.

Is there oil for diabetics??

Although there aren’t any human trials that give CBD to diabetics to see what happens, there are some reasons to think it could be helpful:

Lowering stress. As stated in previous posts, CBD is an effective anti-stress agent. Stress is awful for anyone with diabetes. It increases blood sugar levels. It induces insulin resistance. And if you’re a stress eater, it can increase cravings for high-carb junk food that you really shouldn’t be eating in the first place. In other words, stress exacerbates all the physiological conditions a diabetic is already experiencing.

Improving sleep. Perhaps the most popular use of CBD is to improve poor sleep. Just about the best way to induce some serious glucose intolerance is to get a bad night’s sleep. A diabetic already has poor glucose tolerance; it’s pretty much the defining characteristic of diabetes. What’s worse, a bad night’s sleep has been shown to make a person more susceptible to the allure of junk food.

Inadequate sleep is a strong and independent predictor of type 2 diabetes risk. The less sleep you get, the higher your chance of developing diabetes.

Anything that reduces stress and improves sleep will improve a diabetic’s health. If CBD does that for you, it’ll probably help someone with diabetes. So in a roundabout, not direct way, CBD oil has the potential to help reduce the risk of diabetes and improve the symptoms.

Good MDA folks … does anyone have any experience using CBD oil in lieu of an SSRI to help with anxiety and panic? I’m using CBT techniques to deal with anxiety and panic episodes, and cutting back on my dosage of my SSRI with the intent to eliminate over the next couple of months. I was considering giving CBT oil a try (organic, full spectrum), starting out with just a drop or two and building up to a therapeutic dosage. Also, does CBT oil cause fatigue for anyone? It’s the last thing I want to happen as it’s a big reason I want to eliminate taking the SSRI?

Give it a try, making sure you keep your doctor in the loop.

There are several parallels between anti-depressants and CBD. Both antidepressants and CBD interact with the endocannabinoid receptor systems in the brain. Both antidepressants and CBD can stimulate neurogenesis and counter the depression-related reduction in brain-derived neurotrophic factor.

Any compound that’s used for sleep has the potential to increase fatigue. Sleep is fatigue at the right time. Fatigue is sleep at the wrong time. In an Israeli study of 74 pediatric epilepsy patients using CBD to quell their seizures, 22% reported unwanted levels of fatigue, so it’s a common complaint. Just consider that these were kids taking fairly high dose CBD to quell seizure activity, and that you may not have the same issue taking lower doses at a higher body weight.

Does CBD oil break my fast?

The dosages involved in most CBD oils include at most 1/8 teaspoon of carrier oils, so that’s not enough calories to impact your fast in any meaningful sense.

I haven’t seen any evidence that CBD itself inhibits or impedes ketosis, autophagy, or fat-burning. So, no, there is no indication that CBD oil breaks your fast.

How do I figure out how much cbd is in hemp oil?

As I indicated earlier, it’s impossible to know unless you buy a hemp oil that explicitly states the CBD content.

CBD oil is so expensive. Are there any other options for getting CBD?

You could make your own. It’s actually legal to buy “CBD flower,” which basically looks exactly like the cannabis or weed you’d buy on the street or at a legal dispensary, only it contains little to no THC and tons of CBD. One recipe I saw involved slow-cooking an ounce of the CBD flower in a cup of coconut oil for 8 hours, then straining out the solids. Whatever method you use to cook it, it requires fat, as cannabinoids are fat-soluble.

Here’s a place you can buy CBD flower online. (Note: I don’t have any experience with that company or any other that markets CBD flower or CBD products, so buyer beware.) There are many such places. Just search for them.

CBD is everywhere these days. Should I definitely use it?

Not necessarily. Like anything, it has its uses, there’s great potential, and as new research comes out I foresee the discovery of new modes of action and new applications. However, in all fairness, it’s being overhyped when promoted as a cure-all or panacea.

For what it’s worth, I’m not using it myself. I don’t feel the need, haven’t felt a “CBD deficit.” Don’t assume it’s yet another essential supplement that you simply must have. The basics are the important things—sleep, food, exercise, community, love, micronutrients.

CBD is best used for people who have an established need for it. Chronic pain patient who wants to stop using so many opioids? Great candidate. Kid with epilepsy for whom keto and meds aren’t working? Give it a try. Anxiety and insomnia? Better than just going with narcotics right off the bat. (But as always, work with a physician for any medical issue.)

That’s it for today, folks. If you have any more CBD questions, write them down below and I’ll be sure to answer them!

I left the pro athlete world a long time ago. I no longer compete. I don’t train with the intensity and volume it’d take to win races. But I do pay attention to what’s going on in that world, and I still have a lot of friends who never left it. Developments there often foreshadow developments in the rest of the health world. And after things like keto, MCT oil/ketones, and collagen, the performance hack that’s blowing up among elite athletes is CBD oil. Almost everyone I talk to who puts in serious training and competing time (in a variety of sports and pursuits) is dabbling with CBD.

What are they using it for?

There are two main claims when it comes to CBD and fitness.

  • That it improves sleep.
  • That it reduces pain, improves workout recovery, and helps you get back to training and competition.

Do their claims have any scientific support?

CBD and Sleep

A big review of CBD and sleep found that CBD increased sleep time and reduced the number of times people woke up during the night, improved sleep quality, reduced REM-related behavioral disorder (where you act out your dreams in your sleep), and improved sleep in anxiety patients.

Sleep is one of the biggest weak spots for many athletes. They sacrifice sleep for gym time. They train late at night under bright lights and come home energized and unable to get to bed. They focus on the workouts rather than the recovery. But here’s the thing: the more you train, the more sleep you need. The more performance you need to wring out of your body, the higher your sleep requirements are going to stack. There’s no getting around it. Sleep is one of the most important things to get right if you want to improve performance and make your hard work count for something.

But let’s get more granular. You want details?

Sleep deprivation ruins your posture and makes you more liable to make technique mistakes, get injured, and compromise movement quality and power. If you can’t coordinate your limbs, you won’t succeed in the gym or on the field (and you’ll probably make a critical mistake that gets you hurt).

Sleep deprivation kills your judgment. If you’re not thinking clearly, you’ll make silly mistakes and dangerous choices. Go for the last rep on the deadlift when your back’s about to give out, that sort of thing.

Sleep deprivation squanders your adaptation to training. Enjoy the insulin sensitivity and improved energy utilization training provides? Sleep loss blunts both. Like gaining muscle in response to lifting heavy things? Sleep loss inhibits muscle protein synthesis.

Sleep deprivation makes eating well harder. If you’re training for fat loss and body composition, you know that eating is well over half the battle. A single night of bad sleep makes you more vulnerable to the rewarding effects of junk food. It becomes harder to resist and more addictive.

Sleep deprivation causes muscle loss. A lack of sleep increases urinary nitrogen, a sign that the body is breaking down lean muscle mass.

So, is there a connection between sleep, CBD, and performance?

That hasn’t been directly tested. We know two things:

  1. CBD can help people who are having trouble sleeping get more sleep.
  2. Sleep is ergogenic. If you aren’t sleeping, you aren’t maximizing your performance in the gym and adaptation to your training.

That’s not to say you can’t get good sleep without CBD. It’s not a requirement for good sleep. But if CBD is helping athletes get better sleep than they would otherwise, it’s also giving them a performance and training boost.

CBD and Pain, Adaptation, and Recovery

One of the biggest quandaries an athlete faces is how to balance pain management, training adaptation, and workout recovery.

You can use ice baths to get back in the game quicker, but you might reduce training adaptations.

You can take two days off after a really tough workout and maximize the training effect, but you won’t be able to compete in the interim.

You can pound NSAIDs to reduce pain, but it might slow down your recovery and impair your adaptation to the exercise.

Everything has a tradeoff. And if you lean too far in one direction, you’ll pay the price. Back when I was competing, I leaned hard toward “getting back out there.” I ate ice cream and grains by the gallon to replenish the energy I expended, popped Tylenol like candy to dull the pain long enough to let me get through the next workout. It all worked out in the end (I wouldn’t be doing this if I hadn’t messed up so badly), but boy if I didn’t cut it close.

Where Does CBD Fit In?

CBD is a potent antioxidant and anti-inflammatory. It can block neurotoxicity from oxidative stress. It lowers inflammatory cytokines and raises anti-inflammatory cytokines. It may reduce a person’s reliance on opioids for pain control. It can even synergize with NSAIDs, reducing the amount you need to get the same effect. And it can do all this without causing liver damage. Sounds uniformly beneficial, right?

Be careful. Anti-inflammation can be a double-edged sword. After all, inflammation isn’t wholly pathogenic:

The inflammatory response is the healing response.

Training adaptations occur in response to the inflammatory effect of exercise.

The inflammatory reactive oxygen species that we’re all so worried about also serve as cellular messengers that provoke the creation of new mitochondria and the production of endogenous antioxidants like glutathione.

This is hormesis—the application of good stressors to make us healthier, stronger, and more resilient.

NSAIDs have many of the same effects, like blocking inflammatory cytokines, and have been used by athletes for decades to reduce pain, improve acute performance, and hasten the return to competition. They’ve also been shown to reduce muscle adaptations to resistance training and impair healing even as they reduce pain.

One of CBD’s anti-inflammatory effects is to blunt the release of interleukin 6 (IL-6), an inflammatory cytokine. This isn’t always helpful, as studies show. A hard training session spikes IL-6, and, at least in animal studies using IL-6 knockouts (mice who produce no IL-6 at all), lack of an IL-6 response tends to reduce muscle and adipose tissue adaptations to exercise. NSAIDs are another anti-inflammatory drug that block IL-6 and have been shown to impair muscle adaptations to resistance training in the young and improve them in the elderly. In other words, NSAIDs impair the hormetic stress effect of exercise in the young (who tend to have a lower stress burden and higher stress resilience) and enable it in the elderly (who tend to have lower stress resilience).

What Does This Mean For You?

Well, it depends on who you are and your situation.

High stress lifestyle? CBD can probably help you blunt some of your underlying stress to give the training a bigger effect. Low stress lifestyle? CBD might blunt it too much and render your training less adaptive.

As for CBD’s effect on pain means, there are a lot of unanswered questions that I trust will be answered in due time.

CBD may help mask the pain from injuries by exerting anti-inflammatory effects while slowing down healing. However, if your baseline inflammatory status is high, reducing inflammation may be just what you need to improve healing.

CBD may help reduce pain by speeding up the healing process. There’s even some evidence in rodents that CBD can speed up the healing process of a fractured bone. Does that happen in humans? Does that happen in other types of injuries? Maybe.

That said, if taking CBD before a workout is the only thing that lets you actually get through the workout without pain, it’s going to be better than not taking it. I know of a few people who swear by CBD for joint relief; they couldn’t do what they love without it.

We have a lot more to learn about CBD and training. The benefits for athletes who need help with sleep are clear and well-established. The benefits for athletes who need help with pain and recovery are murkier—we simply don’t know the details yet. It’s likely that CBD will help athletes recover in some situations and not in others. But for the most part, it’s relatively low-risk. Give it a shot and see what you notice. The beauty of it all is that even if CBD impairs your training adaptation, it’s not set in stone. The safety profile is good. The research is only growing. You can always drop it and keep training and regain your gains.

That’s it for today, folks. Have you used CBD to enhance your training? Did it work? Did it hurt? Tell us all about it down below!

Anxiety is normal. It’s something we all have experience with—to one degree or another. Most people are anxious about something that hangs over them and follows them around like a personal rain cloud. Then there’s the deeper but still familiar anxiety many of us carry. The anxiety about our self-worth. The anxiety of performance, of social situations. This type can grip us in an uncomfortable, but hopefully not chronic, way.

But not all anxiety is run-of-the-mill—or manageable. People with Generalized Anxiety Disorder, for instance, might have trouble leaving the house, ordering a coffee from Starbucks, going to work. Anxious thoughts cycling through their brains often keep them up at night. When untreated, people with this level of anxiety can end up living in a state of perpetual fear.

The conventional approach is to take anti-anxiety meds, which can be genuinely life-saving for some people. Nonetheless, these can come with downsides that vary depending on an individual’s dosage and reactions—and the nature of the particular medication itself. Some meds result in few side effects, but others’ effects can be heavy. For instance, there are the benzodiazepines, highly-addictive tranquilizers with the potential for abuse. They make driving unsafe. They lower productivity. They sedate you. When necessary for the severity of the condition, these side effects may be worth it.

In other cases, a person might have more space to experiment and want to explore a different route.

In some cases, people choose to try natural anxiety aids. These are supplements, nutrients, and herbs that have been designed across millennia by nature (and maybe some input from green-thumbed healers). They might not always be enough for something as serious as a clinical anxiety disorder (please talk to your doctor before making any adjustment or addition to your medication), but at least some may be important complements to a prescribed regimen.

For those who want or need an alternative strategy for anxiety beyond meditative practices and general good health, these natural remedies may be worth a try.

First, the NUTRIENTS….

These are basic vitamins, minerals, and amino acids that your body needs to work. They are non-negotiable. You don’t have to get them through supplements—in fact, that should be a last resort after food—and I wouldn’t expect “drug-level” effects, but you do need to get them.

1. Long Chained Omega-3 Fatty Acids

Some human evolution experts maintain that the human brain wouldn’t be the human brain without steady and early access to coastal food resources—fish and shellfish rich in long chain omega-3s. If the long-chained omega-3s found in fatty fish and other sea creatures made our brains what they are today, it’s safe to assume that our brains work better when we eat them today. And if we’re talking about anxiety, that appears to be the case:

Studies in substance abusers find that supplementing with enough fish oil (and, yes, here’s what I use regularly) to raise serum levels of the long chain omega-3 fatty acid EPA reduces anxiety, while increases in DHA (the other long chain omega-3) reduce anger. Rising EPA levels after supplementation predicted the reduction in anxiety.

In healthy young medical students, omega-3 supplementation (2 grams EPA, 350 mg DHA) lowered inflammation and anxiety. Follow-up analyses revealed that reducing the serum omega-6:omega-3 ratio also reduced anxiety scores.

And in early pregnancy, high DHA levels predict low anxiety scores.

2. Magnesium

Magnesium deficiency is a risk factor for anxiety. The evidence, considered by some to be low quality, nonetheless suggests that supplementing with magnesium can reduce subjective anxiety. The mechanistic evidence is stronger, as magnesium is one of those minerals that plays a role in hundreds of very basic and essential physiological processes—including the generation of ATP, the body’s energy currency. Without adequate energy production, nothing works well. One’s mental health is no exception.

Magnesium supplementation reduces subjective anxiety (the only kind that matters) in the “mildly anxious” and in women with premenstrual syndrome.

Magnesium L-threonate, a form particularly good at getting into the brain, is worth trying for more immediate, noticeable effects.

3. Zinc

Zinc deficiency is common in people with anxiety, including Chinese males and Americans. And although mainlining oyster smoothies probably won’t fix serious anxiety, a follow-up in the group of Americans with low zinc levels found that zinc supplementation did reduce anxiety levels.

4. Vitamin B6

Vitamin B6, or pyridoxine, helps regulate production of serotonin and GABA—two neurotransmitters that control depression and anxiety. In mice exposed to anxiety-producing situations, pyridoxine increases GABA, reduces glutamate, and reduces anxiety. In humans, correcting a magnesium deficiency with magnesium and vitamin B6 has a stronger effect on anxiety than magnesium alone. (Good to note: women on hormonal birth control may be depleted of vitamin B6 as well as other vitamins and minerals.)

The best sources of vitamin B6 are turkey, beef, liver, pistachios, and tuna.

Now, the NATURAL INTERVENTIONS….

These aren’t essential nutrients. Rather, they’re plant compounds with pharmacological effects and, in most cases, hundreds of years of traditional usage for dampening, inhibiting, or resolving anxiety.

5. Kanna

Kanna comes from a succulent plant native to South Africa. The story goes that an anthropologist noticed elderly San Bushmen nibbling on a particular type of succulent plant while displaying incredible cognitive ability and remaining calm, cool, and collected. The fact that they weren’t dealing with daily commutes, traffic jams, annoying bosses, and mounting bills probably had something to do with it, but it turns out that the succulent plant wasn’t hurting the cause.

Kanna has been shown to dampen the subcortical threat response, which is normally heightened in anxious states. It also increased well-being and resistance to stress in health adults who took it in a safety study.

6. Theanine

Theanine, an amino acid found in green tea and available as a supplement, isn’t going to obliterate your nerves before a big performance. One study showed that it (along with the benzodiazepine Xanax) reduced resting state anxiety but not experimentally-induced anxiety. Then again, neither did Xanax.

Theanine is instead a mild anxiolytic. If you get anxiety from caffeine, take 200 mg of theanine with your coffee. It will smooth out the experience, reduce/remove the anxiety, and leave the stimulation.

7. Kava

Kava is a plant native to the South Pacific. Traditionally, its roots were chewed fresh with the resultant liquid often spit into communal bowls for consumption, pounded to release the moisture, or sun-dried, ground, and steeped in water to make an intoxicating, relaxing mild sedative. Nowadays, the active kavalactones are also extracted and pressed into capsules.

I don’t use kava, but I have tried it a couple times in the past. For what it’s worth, I don’t have anxiety issues but it did seem to pair well with caffeine (similar to theanine).

8. Rhodiola Rosea

Rhodiola rosea is a longtime favorite adaptogen of mine. It hails from the barren wastes of Siberia, where for millennia people from all over the ancient world coveted it. There’s something about the harsh environment of the northern tundra that made rhodiola rosea incredibly resilient—and bestows upon those who consume it a similar type of mental resilience.

2015 study sought to determine the impact of rhodiola on self-reported anxiety, stress, cognition, and a host of other mental parameters. Eighty subjects were divided into either a twice-daily commercial formula (containing 200 mg rhodiola) group or a control group. Compared to the controls, the rhodiola group showed notable improvements in mood and significant reductions in anxiety, stress, anger, confusion and depression after 14 days.

Rhodiola rosea, along with theanine, features prominently in my anti-stress (and anti-anxiety) supplement Adaptogenic Calm. (If you’re interested, here’s a video of me talking about how I use it.)

9. Lavender

There’s a great lavender farm on the island of Maui. One of the favorite memories from that trip is strolling through the fields of lavender, brushing against the leaves and flowers, just basking in the relaxing scent that permeated the entire property. A very low-stress environment, to be sure.

One study gave lavender oil capsules to major depressive disorder patients suffering from anxiety who were already taking antidepressants. Not only did adding the lavender reduce anxiety, it also improved sleep.

Perhaps the most impressive study is this one, where generalized anxiety disorder patients either received lavender oil or a benzodiazepine anti-anxiety drug. Patients receiving the lavender had the same beneficial effects as the benzo patients without the sedation.

Lavender oil aromatherapy also seems to reduce anxiety, at least in cancer patients. One weakness of aromatherapy research is the difficulty of giving a “placebo smell.” Essential oil scents are quite distinct.

10. CBD Oil

As I wrote a couple weeks ago, CBD is the non-psychoactive cannabinoid found in cannabis.

Most recently, a large case series (big bunch of case studies done at once) was performed giving CBD to anxiety patients who had trouble sleeping. Almost 80% had improvements in anxiety and 66% had improvements in sleep (although the sleep improvements fluctuated over time).

In a five-year-old girl with PTSD (a category of patient that just shouldn’t exist) in whom pharmaceutical anxiety medications did not work, CBD oil provided lasting relief from anxiety.

Here’s how to find a good CBD oil.

What do you folks like for anxiety? What’s worked? What hasn’t? What did I miss?

Thanks for reading, everyone. Take care.

Last week, I explored the impact of all the various foods, beverages, and food-like substances people consume while fasting—and hoping to maintain a functionally fasted state in the post, “The Definitive Guide To What Breaks a Fast.” Does MCT oil break the fast? What about coffee, tea, or bone broth?

There were more than a dozen, and I even did a follow-up. Today I’m going to discuss whether commonly-consumed supplements break the fast.

Let’s go:

Fish Oil

Fish oil is pure fat. If you’re taking the average supplemental dose of 1-2 grams of fish oil, it’s not a problem. That’s not even a teaspoon. It’s about 9-18 calories.

You may burn slightly less fat than you would otherwise, but in the grand scheme of things, a few grams of fish oil won’t break the fast.

Cod Liver Oil

Cod liver oil is fish oil with extra vitamin D and vitamin A. As long as you keep the doses low enough, cod liver oil won’t break the fast.

Multivitamin/Multimineral

Multivitamins do not break a fast. They are usually non-caloric. However, not all of their components will be absorbed very well on an empty stomach, so keep that in mind.

If you’re still not on board, note that in the older studies with really overweight people who fasted for upwards of a year straight, they usually supplemented with a multivitamin.

Food-Based Multivitamin

A popular one I’ve seen around—Alive, made from kale and raspberries—has just 2 grams of carbs per dosing. It’s not ideal, but it’s not a deal breaker—or a fast-breaker.

Gummy Vitamins

Gummy vitamins have the potential to be about 5-6 grams of sugar, a gram of protein (from gelatin), and a gram of fat (if including omega-3s) per serving, so they’d arguably break the fast. Plus, they taste like candy and are likely to stimulate cravings and make fasting harder.

Gummy vitamins break the fast.

Potassium

Potassium is non-caloric and does not break the fast. In fact, it can help you handle the fast better by replenishing electrolytes.

Potassium doesn’t break the fast.

Creatine

Creatine contains no calories and has no effect on insulin secretion (or glucose in the absence of calories).

Creatine does not break the fast.

Protein Powder

Protein powder provokes an insulin response, which opposes autophagy, which means you’re breaking your fast. Plus, protein powder contains calories.

I’m going to say “yes, protein powder breaks the fast.

Collagen

If you’re strict and technical, then yes, collagen breaks a fast. There’s evidence that glycine—the most prominent amino acid in collagen—can inhibit autophagy, but it was a convoluted animal study where inhibiting autophagy with large doses of glycine after brain injury actually improved outcomes. It probably doesn’t apply to someone adding a scoop of collagen to their coffee. Besides, even if it slightly reduces autophagy, a little collagen won’t negatively impact ketosis, fat-burning, or energy intake.

I’m going to say “technically yes,” but “realistically no, collagen doesn’t break the fast.” Avoid if your main focus is autophagy, however.

Branch Chain Amino Acids (BCAAs)

BCAAs trigger an insulin response and thus stop autophagy…and the fast. That said, many proponents of fasted training recommend using BCAAs before a workout to help preserve muscle and improve the post-workout anabolic response.

I’m going to say “yes, BCAAs break the fast.”

Vitamin D

Vitamin D is fat soluble and thus comes packaged in an oil carrier, but the dosage is so small that it won’t affect your fast.

Unless you find that 1/8 teaspoon of olive oil ruins your fast, vitamin D won’t break a fast.

Probiotics

Probiotics contain no calories and will not break a fast. However, they are best absorbed in the presence of food—the food protects them as they travel through the digestive system, and most probiotics occur naturally in food—so taking them during a fast is probably, mostly useless.

Probiotics don’t break a fast, but why take them during one?

Prebiotics

Pure prebiotics will not break a fast, as they contain no digestible carbohydrates. Prebiotic-enriched foods will break a fast, as they do contain calories.

Adaptogens

Adaptogens are compounds, usually herbs or herb derivatives, that modulate your stress response. They improve your ability to tolerate and respond to stressful situations; they don’t blindly inhibit the stress response if the stress response is warranted. They keep you honest and counter unnecessary stress responses. They contain no calories, unless you’re chowing down on a big hunk of maca or ashwagandha root. In fact, most adaptogens have traditionally been consumed in tea form, extracting the active compounds and leaving behind any calories. Have at ’em.

Adaptogens do not break the fast.

Mushroom Extracts

Medicinal mushroom extracts come from mushrooms, which are technically food. But the amounts you take are so low—usually no more than a teaspoon—that they won’t impact your fast or provide any significant amount of caloric energy. Four Sigmatic has those “mushroom coffee” blends you add to hot water. They can get up to about 30 calories per serving, but even that’s going to let you maintain most of the fasting benefits.

Mushroom extracts don’t break the fast.

Melatonin

I used to keep the old Trader Joe’s melatonin on hand because it was half a milligram, whereas most other melatonin supplements are in the 3-5 mg range. It was also sweet, tasting like those white Valentine’s Day mint hearts you used to get back in the day. I haven’t come across any sweetened melatonin supplements since Trader Joe’s phased those out, but that’s the only thing I’d worry about on a fast.

Melatonin does not break a fast.

Final Note: Most supplements are okay to take on a fast, though the lack of food may make absorption more difficult. If you have any other questions about supplements on a fast, drop them down below. Thanks for reading, everybody.

On a related note, with supplements on my mind this week I thought it would be a good time to offer one of my favorite deals—just for the MDA community: 20% off my full supplement line, plus Primal Fuel and Collagen Fuel. It’s a great time to stock up on favorites or to try something new. Offer ends 4/24/19 midnight PDT. Use code WELLNESS20 at checkout. (Offer doesn’t apply for autoship orders.)
