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 be ..read more

What's the Deal With Seed Oils? | Masterjohn Q&A Files #329

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 ..read more

Is Hair Mineral Testing Useful? | Masterjohn Q&A Files #328

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 s ..read more

Secrets to Superior Cognitive Performance (Without Drugs)
Chris Masterjohn
by Chris Masterjohn, PhD
4M ago
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 ..read more

How to Find the Root Cause of Autoimmunity? | Masterjohn Q&A Files #327
Chris Masterjohn
by Chris Masterjohn, PhD
5M ago
Question: How to Find the Root Cause of Autoimmunity? Short Answer: Autoimmune conditions are likely driven by deficiencies of vitamins A and D, which contribute to post-infectious autoimmunity by compromising the rhythmic rise and fall of myeloid-derived suppressor cells (MDSCs), and to autoimmunity regardless of infections through impaired suppression of Th17 helper T cells. More broadly, infections and tissue damage are the most likely drivers of autoimmunity onset. However, energy metabolism governs everything through the second law of thermodynamics, which holds that energy must be used t ..read more

Cancer, IV Drips, and the Glutathione-Vitamin C Connection
Chris Masterjohn
by Chris Masterjohn, PhD
5M ago
Is high-dose vitamin C good for you? High-dose intravenous vitamin C can selectively kill cancer cells in live patients and can save sepsis patients from dying, but it acts as a pro-oxidant in cancer and an antioxidant in sepsis. So what does it do in the rest of us? Oral doses of 2000 milligrams raise oxalate levels in most people, and as little as 400 milligrams raises oxalate in some people. This seems to be the most sensitive indicator of a delicate imbalance with glutathione and other factors needed to recycle vitamin C. Such a balance actually needs to be avoided when killing cancer yet ..read more

The ability to become startled is an adaptive behavior that protects us from being injured by a sudden threat, and prepares us for the fight-or-flight response when necessary. Nevertheless, getting startled too easily can be a sign that something is wrong. Here's what to do about it.
