Research Findings On Supplements

  • Pharmaceuticals undergo extensive testing to prove they're effective and safe before they can be sold, but dietary supplements can be sold without proof of claims, effectiveness or safety.
  • Daily multivitamin consumption does not lower heart disease risk.
  • The FDA has found more than 500 supplements adulterated with pharmaceuticals or closely related compounds. Those can cause unwanted side effects and may be especially risky when taken with heart drugs or other prescription medications.

When Buying Supplements

When Buying Supplements

  • Consider only single-ingredient supplements. Multi-ingredient supplements make it hard to identify which substance is having an effect and they are more likely to be adulterated with banned drugs.
  • Tell your doctor about any supplement you take, so they can check it will interact with any of the medicines you're on.
