What are the benefits of taking vitamins C and E together?

There hasn't been much research on the benefits of taking vitamins C and E together versus taking them at different times. However, one 2004 study suggested that older people may be able to reduce their risk of Alzheimer's disease by taking the two vitamins together. The findings suggested that the protection occurs when the vitamins are taken in the high doses typical of individual supplements -- 500 to 1,000 micrograms (or more) of vitamin C and up to 1,000 IU of vitamin E. People in that study didn't seem to lower their risk of Alzheimer's disease if they took either vitamin alone.

Taking high doses of vitamin E may come with some danger, though. Other studies suggest that men who take vitamin E supplements of 400 IU a day may increase their risk of prostate cancer. So talk with your doctor before taking high doses, either with vitamin C or alone.
