On health supplements, again

Thanks again to David McCandless and Andy Perkins, from Informationisbeautiful.net for updating their post on Snake Oil?  “Scientific evidence for popular health supplements”.

You can find here their work which is based on comparing more than 1500 abstracts of studies about health supplements, which are a huge industry. it is notable that they considered only large, human, randomized placebo-controlled trials. No animal trials. No cell studies. Many of the health claims made by the $23 billion supplements industry are based on non-human trials.
