Study explores vitamin-cancer link

University of Washington researchers followed more than 77,000 people for four years.

They found that people who took a multivitamin, vitamin C or folate supplements had the same risk of lung cancer as those who took none.

However, among vitamin E users, people who took a higher dose had a greater risk of lung cancer.

The recommended amount of vitamin E is 15 milligrams a day. Many in the study were taking much more.

Experts say these findings show that just because they're natural, doesn't mean vitamins are harmless.
