Do we need nutritional supplements?

February 22, 2011

Here’s a good post by Harriet Hall at the Science Based Medicine blog on nutritional supplements. She concludes:

  • As my correspondent put it, “the public mania for nutritional supplements is baseless.”
  • In general, all our nutritional needs can be supplied by an adequate diet.
  • Supplements are beneficial for a few specific evidence-based indications; otherwise, they offer no benefits and may even be risky.
  • Diet supplements are not medicines, but are being used as medicines.
  • DSHEA should be repealed.
