Vitamins & antioxidants

It's a common question: Should we be taking vitamins or antioxidants to reduce the risk of having a heart attack or heart disease?

The researched answer, as at January 2013, is that there is no evidence to support the use of vitamin and antioxidant supplements for prevention of cardiovascular diseases.

  • This statement is from a very large systematic review and meta-analysis published in a high quality medical journal.
  • It reviewed 2240 articles and analysed the best 50 studies which were randomised controlled trials.  
  • By combining these studies, 294 478 participants (156 663 in intervention groups and 137 815 in control groups) were identified that could be included in the final analyses.
