Health’s Guide to Supplements


Easy-to-understand reports on scientific studies of health supplements makes it easy to look up what actual scientific studies say on various supplements. From popular supplements like vitamin D and fish oil, to more esoteric ones like berberine and spirulina, this website has it covered (and over 17000 citations).

The site became really useful when it released what it calls “The Human Effect Matrix.” It summarizes clinical human trials and lets you immediately know what effect each supplement has (and how strong that effect is).

As someone into weight lifting, it’s helped me realize what junk supplements like glutamine and tribulus terrestris are.
