I recently wrote a paper summing up the negative effects of vitamin C supplements.  This morning I read a new study on vitamin C and cataracts.  The study found that women age 65 and up who supplement with vitamin C has a 38% increased risk for developing cataracts!

Eat food!  That is the secret to optimum nutrition.  Supplements should be food based.  Taking labratory produced antioxidants to try and substitute for nature's bounty just doesn't work.
