The Winter 2005/Spring 2006 issue of Wise Traditions carried my article on vitamin A and osteoporosis, in which I argued that vitamin A only contributes to osteoporosis when vitamin D intakes are very low.

Tufts University Confirms That Vitamin A Protects Against Vitamin D Toxicity by Curbing Excess Production of Vitamin K-Dependent Proteins
Tufts University confirmed my hypothesis that vitamin A protects against vitamin D’s induction of renal calcification (kidney stones) by normalizing the production of vitamin K-dependent proteins in December, 2008, without citing my hypothesis or telling me they had confirmed it. I am, of course, very grateful that they thought it significant enough to investigate. I …

This episode was cut from the original Q&A session that you can find here. DISCLAIMER: …
Releasing Iron in Long-COVID: Copper, Fasting, and Cooling Inflammation
Last week I published two articles on iron, one suggesting it could play a role in post-COVID fatigue and hair loss, and the second suggesting it could play a nearly identical role in the same symptoms when resulting from COVID vaccination. In these posts I did not recommend indiscriminate iron supplementation. Rather, I suggested it …

The First RCT Shows Blocking IL-6 Improves Hypoxia in COVID-19
September 1, 2020 We now have the strongest evidence to date that IL-6 plays a direct role in hypoxia in COVID-19, and as it turns out this is bullish for the use of vitamin D and lactoferrin.
