Dr. Tom Guilliams, our go-to expert for anything related to nutrition research, returns to the Evolution of Medicine podcast for the second part of our Controversies in Nutrition series. Dr. Guilliams has written several books on the therapeutic uses of nutritional supplements.

Our guest opens the discussion by rebutting attempts by major medical journals to discredit nutraceuticals. He breaks down the weaknesses of their research and arguments, along with how the studies are biased and unscientific. He also reviews the limitations of specific nutrient biomarkers, realistic expectations for improving methylation through folic acid supplementation, and how to assess optimal vitamin D levels in individuals who receive plentiful sun exposure.
