ScienceDaily (Feb. 21, 2008) — Six-year vitamin E supplementation increased tuberculosis risk by 72% in male smokers who had high dietary vitamin C intake, but vitamin E had no effect on those who had low dietary vitamin C intake, according to a study published in the British Journal of Nutrition.

Previous studies had suggested that vitamin E might improve the immune system. In animal studies vitamin E seemed to protect against various infections.

As usual, balance is important.
