Supplements "affect cancer treatment"
28 May 2008
Vitamin supplements could reduce the effectiveness of some cancer treatments, according to research results published in the [US] Journal of the National Cancer Institute. A team at the Naval Medical Centre in San Diego, California, says vitamin E and beta carotene may have this effect. Dr Brian Lawenda and colleagues say their review of evidence from a number of trials suggests antioxidant supplements may be associated with reduced survival rates, and add that they have “serious concerns” about the potential for harm.
