Information Is Beautiful has a nifty interactive chart that shows the science behind the effectiveness of popular health supplements. You can select various conditions to find out if a certain supplement does anything to help.

The remarkable feature is that all of those circles are actually hyperlinks that connect to an abstract of the study. Pretty impressive.

So for example, the chart shows Evening Primrose Oil is worthless in fighting PMS, but garlic is effective for lowering blood pressure.

There’s a lot of conflicting information on these popular food supplements, but this chart at least makes sorting the strong and less promising data look cool.
