Last Straw

Great chart by Inform­a­tion is Beau­ti­ful:

It’s a “bal­loon race”. The higher a bubble, the greater the evid­ence for its effect­ive­ness. But the sup­ple­ments are only effect­ive for the con­di­tions lis­ted inside the bubble. You might also see mul­tiple bubbles for cer­tain sup­ple­ments. These is because some sup­ple­ments affect a range of con­di­tions, but the evid­ence qual­ity var­ies from con­di­tion to con­di­tion. For example, there’s strong evid­ence that Green Tea is good for cho­les­terol levels. But evid­ence for its anti-cancer effects is conflicting.
