Meet Mark

Let me introduce myself. My name is Mark Sisson. I’m 63 years young. I live and work in Malibu, California. In a past life I was a professional marathoner and triathlete. Now my life goal is to help 100 million people get healthy. I started this blog in 2006 to empower people to take full responsibility for their own health and enjoyment of life by investigating, discussing, and critically rethinking everything we’ve assumed to be true about health and wellness...

Life In the Sanitized Bubble (Or Why Probiotics Are So Important)

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.

Dear Mark: Vitamin K2 and Microworkouts

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?

Dear Mark: CBD Edition

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.

CBD For Performance: What We Know So Far

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?

10 Natural Anxiety Remedies

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 … Continue reading “10 Natural Anxiety Remedies”

What Breaks a Fast: Supplement Edition

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.
