The new study tracked cancer risk in 14,641 male U.S. doctors who took either 400 IU of vitamin E every other day or a placebo, or 500 milligrams of vitamin C daily or a placebo. Their average age was 64 at the start of the study, and they were followed for eight years on average.(Read entire article)

Even when researchers compare people's diets and find that a vitamin seems to help, the benefit may not translate when that nutrient is obtained a different way, such as a pill.

"Antioxidants, which include vitamin C and vitamin E, have been shown as a group to have potential benefit," but have not been tested individually for a long enough time to know, said Howard Sesso of Harvard-affiliated Brigham and Women's Hospital in Boston.(Read entire article)
