Copenhagen University research has suggested that certain vitamin supplements do not extend life and could even lead to a premature death.

A review of 67 studies with trials involving 233,000 people found “no convincing evidence” that antioxidant supplements cut the risk of dying,” and suggested that vitamins A and E could interfere with the body’s natural defences, and that beta-carotene, vitamin A, and vitamin E seem to increase mortality.

The researchers linked vitamin A supplements to a 16% increased risk of dying, beta-carotene to a 7% increased risk and vitamin E to a 4% increased risk.
