By Mark Sisson

18 Comments

For today’s edition of Dear Mark, I’m answering questions from last week’s olive oil post. First, is there a way to identify real olive oil and distinguish it from fraudulent olive oil? Second, should EVOO be used when grilling food? Third, how can we know if our canned seafood is packed in real, actual olive oil and not some industrial seed swill? Fourth, is algae oil worth eating? And fifth, what about just eating whole olives? Finally, why not just eat beef fat, which is also relatively high in MUFA?

By Mark Sisson

14 Comments

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?

What are the respective benefits of vitamin K1, vitamin K2 MK-4, and vitamin MK-7? Where can we find each one?

Hi Mark,

By Mark Sisson

For today’s edition of Dear Mark, I’m answering a few questions from recent comment boards. First, with all the scary tick-related news coming out lately, are there any non-toxic tick repellents that actually work? Are there essential oils that repel and/or kill ticks? Is there a safer way to use insecticides? Next, were the people in the Mediterranean keto study actually eating a kilo of fish on their fish days? And is the wine an important part of the Mediterranean diet? Is the wine therapeutic or just for pleasure?

By Mark Sisson

For today’s edition of Dear Mark, I’m answering questions from last week’s Collagen vs Whey post. You guys had a lot of questions, mostly about collagen, and I’m here to answer them. Can collagen help with plantar fasciitis? Should you take collagen and whey together in the same smoothie, or do they cancel each other out? If a person can’t have whey, is there an equivalent protein powder source? Is glycine a good replacement for collagen? What about liquid whey from raw milk—how does it compare to powdered whey? If I wanted to get my glycine from foods, what would I need to eat and how much of it?

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.

For today’s edition of Dear Mark, I’m answering a round of questions drawn from the comment section of the “What Breaks a Fast” post. You folks had tons of follow-up questions about whether other types of foods or compounds break a fast. Does a teaspoon of honey? Does elevated insulin from BCAAs? Does coconut milk? Does pure prebiotic fiber? What about longer fasts—are they recommended? And how about unsweetened cocoa powder? What explains my ability to predict your questions? Do sausages break a fast? Does liquor? How should you exercise? (For questions on supplements, check out this week’s feature: “What Breaks a Fast: Supplements Edition.”)
