How Lactate Alkalinizes Your Muscles
Mastering Nutrition
For a long time, most people believed that when we exercise, our muscles make lactic acid, this acidifies the muscles, and the acidity contributes to contractile failure, fatigue, and delayed-onset muscle soreness. Some people still believe this. You may have heard the argument against it from well-known figures like Andy Galpin, or, if you’re deep into the science, you may have read the work of George Brooks. In this lesson, we are going to cover the biochemistry of lactate production. We will see that we never make lactic acid, ever. We make lactate. Making lactate is fundamentally...

D-Lactate: Groundbreaking Research No One Is Talking About
Mastering Nutrition
D-lactate is commonly stated to be exclusively a microbial metabolite. This is found in assumptions within the medical literature for decades even when it was long-known to be false. While D-lactate is indeed made by bacteria, D-lactate is also inarguably and irrefutably produced by human enzymes. In this podcast, moreover, I will argue the following: Microbial contribution to D-lactate in humans under normal circumstances is negligible. I coin the term “the D-lactate shuttle” to describe a role for D-lactate that should eventually make its way into biochemistry textbooks...

Your Cells Are Starving For Creatine
Mastering Nutrition
Creatine is like your second mitochondria. Or, the mitochondria’s chief of staff. Or its co-pilot. Your mitochondria make ATP so you can see clearly, hear accurately, digest your food, power your brain, show off your your shiny skin, lift heavy things, and perform your best at the challenges you face. They do that all with the help of creatine. Creatine is responsible for spreading the impact of mitochondrial ATP production into the general area of the cell known as the cytosol, and into every organelle outside the mitochondria. While it is more important in cells with high ATP...

Is Whole Food Vitamin C Really Different? | Masterjohn Q&A Files #330
Mastering Nutrition
Question: Is whole food vitamin C superior to natural because it is part of a tyrosinase complex? Short Answer: Vitamin C is nearly ubiquitously distributed in plant tissues, and is never bound to any enzyme as a structural complex. Vitamin C promotes absorption of iron from plant foods, inhibits copper absorption, and de-loads copper from ceruloplasmin, which may play a role in distributing copper to tissues. Vitamin C is not capable of destroying ceruloplasmin. These functions follow directly from vitamin C as an electron donor and there is no evidence whatsoever that whole food vitamin C...

What's the Deal With Seed Oils? | Masterjohn Q&A Files #329
Mastering Nutrition
Question: What Is the Real Issue With Seed Oils? Short Answer: The main issue with seed oils is that they present an oxidative liability. They do not acutely cause oxidative stress, but their polyunsaturated fatty acids (PUFAs) are more vulnerable than any other macronutrient to oxidative damage. Oxidative stress can increase because of nutrient deficiencies, toxins, infections, other sources of inflammation, alcohol, or smoking, and it will inevitably increase as a function of aging. As oxidative stress increases, more PUFAs in the tissues mean more damage. At least 0.6 milligrams of vitamin...

Is Hair Mineral Testing Useful? | Masterjohn Q&A Files #328
Mastering Nutrition
Question: How useful is hair trace mineral analysis (HTMA) for nutritional testing? Short Answer: Hair trace mineral analysis is included as an optional add-on in the comprehensive nutritional screening from Testing Nutritional Status: The Ultimate Cheat Sheet, because it can capture data for some ultra-trace minerals for which there are no better-validated tests, and it might capture a pattern that might not be picked up as quickly with blood work, such as a mineral transport issue. However, its utility is limited by the fact that hair mineral content is not well validated as a test for any...

Secrets to Superior Cognitive Performance (Without Drugs)
Mastering Nutrition
Nutrition is far more powerful than drugs to improve cognitive performance. We start by looking at cocaine, Adderall, and Ritalin, and show why these drugs cannot possibly hold a candle to nutrition. Optimal nutrition can definitely optimize the function of dopamine, norepinephrine, acetylcholine, histamine, creatine, and the methylation system, and in doing so can simultaneously optimize focus, motivation, sustained attention, and mental flexibility, and methylation, all while eliminating anxiety, depression, and distraction. Yet, popular nutritional cognitive stacks in the nootropic space do...
