Unless there is documented specific vitamin deficiency
there is no evidence vitamin supplements do us any good, and they may even be do harm to us.One of the recent review, involving 232,000 participants, compared those taking the supplements with those who took a placebo or received no treatment. The supplements studied were beta-carotene
(a precursor of vitamin A
that is converted into the vitamin in the body), vitamin A, vitamin C, vitamin E
and selenium. The study didn’t favour the routine supplement of such vitamin supplements at any age group.
