People from all over the world have sent their comments to many news sources expressing concerns about a newly published Cochrane review that shows no evidence for vitamin benefit
The review looked at 67 studies involving 233,000 people who were either sick or healthy and had been taking very high-dose synthetic vitamins supplements for disease prevention. The outcome that they looked at was death from any cause and the researchers found no reduction in death from taking antioxidant supplements. They also found increased risk of death from vitamin A, beta-carotene and vitamin E, but no significant effects from vitamin C or selenium.
The authors concluded that there is "no evidence to support antioxidant supplements for primary or secondary prevention" and sufficient evaluation should be carried out before marketing these supplements.
