On May 25, members of the CMJ Masterpass joined me, Chad Macias, Danny Lennon, and Alex Leaf in a live Zoom meeting to ask us anything about sports nutrition, and here’s the full recording!

We talk about things like:

  • Is there a risk of depleting histidine with beta-alanine supplementation?
  • What’s the best form of fuel to use during a workout? Candy, or something else?
  • Nutritional strategies for recovery from soft tissue injuries to muscles, tendons and ligaments from lifting?
  • Is AMPK the primary regulator of mitochondrial biogenesis in muscle, and does it matter?
  • Can riboflavin help with exercise performance?
  • Why the post-workout anabolic window DOES matter, and why you should NOT eat too much protein BEFORE lifting.
  • Take BCAAs, or just eat protein?
  • Should athletes cycle caffeine, and does it matter if they are fast or slow oxidizers?
  • Nitric oxide: does it have important effects by modifying proteins, rather than just affecting blood flow?
  • Is it delayed-onset muscle soreness if it happens all the time? Or is it a pathology?
  • Transdermal carnosine (Lactigo) for fibromyalgia, the role of glutamate and neurotoxicity in fibromyalgia and delayed-onset muscle soreness (DOMS), and my own experience with using high blood glutamate to identify how acidity was wrecking me after workouts.
  • Maximizing muscle growth and optimizing performance on a low-protein diet.
  • Best time to take Tru Niagen (nicotinamide riboside) and TMG (trimethylglycine), especially the purpose of increasing exercise tolerance.
  • How important are refeeds for dieters?
  • Carbohydrate periodization for endurance athletes?
  • Is there any value to training low during those times where you depend on glucose to either try to train your body to better tap into limited glycogen stores or to try to create a better aerobic response?
  • Besides leucine, what could help increase protein synthesis to prevent sarcopenia in older adults who strength-train regularly? 
  • For muscle growth, what generally applies to everyone?

All this and much more!

This is part 2 of the pantothenic acid Mastering Nutrition podcast. Pantothenate is also known as vitamin B5! It supports your mood, mental health, skin clarity, energy, sleep, and comfort.

Alex Leaf and I team up again, this time to how to get B5 from foods and supplements, and how to know when you’re getting enough.

When you aren’t getting enough, you may suffer from fatigue, apathy, discomfort, uneasiness, or pain. You may get numbness and tingling in the hands and feet. You may get depressed, quarrelsome, childish, or want to spend all day in bed. Your pulse may get higher than you’d expect after minor exertion. Your sleep gets trashed. You get muscle cramps and abdominal cramps, you fart more, and when things get real bad you might throw up.

The best test for measuring B5 status is urinary pantothenic acid. Currently, the only place I know where to get this is the Great Plains OAT test. Hopefully someone will offer it as a standalone. Blood tests are not very useful. 😔

Official recommendations suggest we only need about 5 milligrams per day. In the podcast we discuss why some people might need GRAMS per day. 

❗❗❗There aren’t ANY supplements on the market that have the major forms of B5 found in food. There is good reason to think that food B5 is superior to supplements such as pantothenic acid and pantethine.❗❗❗

I recommend shooting for 10 milligrams per day from food, and then supplementing more when necessary:

  •  2 heaping tablespoons of unfortified nutritional yeast gives you 10 mg.
  •  2 100-gram servings of roasted sunflower seeds or the livers of chicken, beef, lamb, or veal will give you this, but I recommend limiting liver to two servings per week.

  • 3 100-gram servings of gjetost cheese, black and red caviar, kidney from lamb imported from New Zealand, pork liver (and most products made from it), shiitake mushrooms, or canned grape leaves will do the trick.

  • Most fresh cuts of muscle meat give you enough in somewhere between 3-5 100-gram servings, though some require up to four pounds and the data is pretty messy.

  • Five 100-gram servings of any of the following will work: eggs, duck, goose, emu, fresh salmon or trout, raw avocado, canned chilli, peanuts, peanut butter, cashews, white or portabella mushrooms, liver pate (limit to 5 servings per week), giiblets or heart from chicken or turkey, beef thymus or heart, pork kidney or brain, or lamb brain.

  • The following can give you enough if you eat four pounds of them: whole grains, most natural dairy products besides butter, most seafood that isn’t canned, most beans that aren’t canned, raw coconut, most nuts and seeds, and most processed meats.

Here are a few reasons to supplement:

  • One gram of pantothenic acid from sodium or calcium pantothenate has been used for rheumatoid arthritis, and 2-10 grams per day have been used for acne. In acne, a topical cream containing dexpanthenol (a cream-soluble form of B5, the cream usually marketed as wound-healing cream) is combined with the oral dose.

  • 300 mg pantethine 3 times per day lowers cholesterol.

These doses appear extremely safe, with only a very small proportion of people experiencing minor side effects even at these very high doses.
