Snake Oil? Visualization of Science vs Health Supplements

Once again InformationIsBeautiful hits one out of the park.
Today’s fun is an interactive page ranking the scientific evidence proving a certain health supplement is effective vs it’s popularity.
Some surprises: Fish oil, folic acid, St Johns Wort, and green tea are well established with proveable scientific evidence to their benefits.
At the other end of the spectrum, Green tea, anti-oxidants, vitamin A and vitamin E have very little evidence as to their effectiveness.
