Yes.

I have a bee in my bonnet about vitamins, so I tend to keep posting the same message on these sorts of threads.

Here's the Cochrane review on antioxidants: Cochrane review

And here's an extract:

Quote:
Our Cochrane review from 2008 demonstrated that antioxidant supplements seem to increase mortality. This review is now updated.
Quote:
The increased risk of mortality was associated with beta-carotene and possibly vitamin E and vitamin A, but was not associated with the use of vitamin C or selenium. The current evidence does not support the use of antioxidant supplements in the general population or in patients with various diseases.
From the conclusions:

Quote:
We found no evidence to support antioxidant supplements for primary or secondary prevention. Beta-carotene and vitamin E seem to increase mortality, and so may higher doses of vitamin A. Antioxidant supplements need to be considered as medicinal products and should undergo sufficient evaluation before marketing.
