We know that it's generally healthier and safer to EAT your vitamins and minerals via a multi-colored array of whole plant foods. As John McDougall, MD notes: flooding the body with isolated, concentrated nutrients creates imbalances, increasing the "risk of disease and death." Thus, for years I've been taking only two supplements: B12 and D3. But, a postby Dr. Michael Greger gave me pause:
Vitamin B12: The RDA is only 2.4 mcg/day; I've been taking 1,000 mcg, twice weekly, of sublingual methylcobalamin [a natural source of B12]. I was surprised that Greger recommended "at least 2,500 mcg of cyanocobalamin," a synthetic derivative of B12. However, Matt Lederman, MD (who did the "supplements" lecture for my plant-based certification) and Dr. McDougall both recommend methylcobalamin B12. I'm sticking with this form. But, as Greger recommends, I now take B12 every other day and on an empty stomach.
