We do a lot of data visualization here on Walker Tracker, not the least of which is using maps to visualize data (oops! Not yet announced!). For this reason, I really love the work of David McCandless on informationisbeautiful.net. He takes huge amounts of data and makes it visually stunning, and very easy to, for lack of a better word, grok.
His latest work – “Snake Oil? Scientific Evidence for Health Supplements” is relevant to anyone who ponders whether to take a Vitamin C for their next cold (spoiler: maybe), take Folic Acid if you’re pregnant (spoiler: Yes!), or Vitamin E for your heart (spoiler: might be best to try something else).
As my friend Dr. David Naimon pointed out, not all supplements are evenly studied. The chart might be a little deceiving as some of the items low on the list may have also received inadequate testing.
