Panacea or Snake Oil?
With the multitude of health supplements out there, it’s difficult to figure out which ones work and which ones do not. Ideally, we’d follow the results of good scientific studies that have been corroborated by other studies. Unfortunately, wading through the results is extremely difficult. There is a good attempt and collating some of the results and categorizing the benefits by the reliability of the evidence. The people at Information is Beautiful have made a very nice bubble visualization of a whole host of supplements and the level of evidence for their supposed benefits. They even have a Google Doc with their source info that can update the visualization! Great work.
