Information is Beautiful, a data visualization website, has a thought-provoking interactive that shows supplements charted by the strength of evidence that indicates they're beneficial. Nevertheless, there are a handful of vitamins and supplements that, studies suggest, might actually be worth taking for people with specific conditions. In many cases, taking high amounts of them in a refined form (especially vitamins A, C and E and beta carotene) can actually be harmful, increasing the risk of cancer and other diseases by excessively inflating the concentration of antioxidants in the body. Of course, our bodies do need these vitamins to live-it's just that the diet of most people who live in developed countries in the 21st century already includes them in abundance. Study after study has shown that vitamin C does nothing to prevent common cold, a misbelief that dates to a theoretical suggestion made by a scientist in the 1970's. Controlled, randomized studies-where one group of people take supplements and another takes placebos, and the groups are compared-have produced little evidence that antioxidants protect against cancer. Multivitamins don't reduce the chance of cancer or cardiovascular disease. This goes for a tremendous range of supplements that you might imagine to be beneficial. " Enough is enough: stop wasting money on vitamin and mineral supplements," declared an editorial that was published in the December 2013 issue. In the last few years, a number of studies published in the Annals of Internal Medicine underscored a fact that scientists have become increasingly sure of: The vast majority of vitamins and mineral supplements are simply not worth taking.
