This has to be my favourite figures of the year so far. What with new year's resolutions I'm sure a few people have been looking into "supplements" as part of keeping healthy. Skeptics should take note that science is more than happy to say something works if they have evidence for it.
There's quite a few surprising ones on there for me such as Vitamin C not being that great for colds while Zinc is pretty good for them.
The nice thing about this figure is that it is constantly being updated so things could change as new results come out. There's also a nice section explaining where the information comes from so for the super skeptic you can find the actual studies and decide how "real" they are.
