Scientific evidence for popular health supplements

(Showing tangible human health benefits when taken orally by an adult with a healthy diet)

Information is beautiful - This visualization generates itself from this Google Doc. So when new research comes out, the data is quickly updated and the image regenerated. (How cool is that??)

Note: You might see multiple bubbles for certain supplements. These are because some supplements affect a range of conditions, but the evidence quality varies from condition to condition. For example, there’s strong evidence that garlic can lower blood pressure. But studies on whether it can prevent colds have produced inconclusive results. In these cases, the supplement is given another bubble.
