“This image is 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.”
The graphic shows the effectiveness of health supplements on the Y-axis (higher is better), and uses the size of the bubbles to illustrate the popularity of that particular supplement among US adults. Anything below the “worth it line,” doesn’t have enough evidence of medicinal benefit and is probably not worth your time, according to the graphic’s creators, who looked at data from over 1500 studies on both PubMed (US National Library Of Medicine) and Cochrane.org. The infographic effectively combines data on both popularity and medical benefits to create a resource that points out the best health supplements, as well as which ones American consumers believe in the most.
