Some critical responses to this new study are starting to accumulate: Dr. Peter Attia's takedown: https://peterattiamd.com/vitamin-d-nejm-study/ Dr. Ronald Hoffman: https://drhoffman.com/article/whats-up-with-that-vitamin-d-s... Council for Responsible Nutrition: https://www.nutraingredients-usa.com/Article/2022/07/29/crn-... And a 3-part series from non-profit GrassrootsHealth (only 2 parts so far that I see): part 1: https://www.grassrootshealth.net/blog/go-part-1-3-headlines-... part 2: https://www.grassrootshealth.net/blog/go-part-2-3-vital-anal...
