Direct link: http://www.informationisbeautiful.net/play/snake-oil-supplements/ http://www.informationisbeautiful.net/play/snake-oil-supplem... Interesting, but not very comprehensive. A number of supplements that I've found relevant to recommend to friends, including GABA, 5-HTP and levodopa are absent from the graphic (or did I miss them?). It's also problematic that some of the conditions indicated are very general. There are many possible biochemical causes for depression or insomnia, and a treatment that works for one might have no effect on another.
