But the proven benefits of a few supplements pale next to the growing concerns about widespread vitamin use. Nobody knows why high doses of vitamins taken as pills might cause harm. One theory has to do with free radicals, a common byproduct of the normal chemical reactions that occur in cells. Every day cells get damaged due to a variety of factors including sunlight, the foods we eat and natural aging. This creates free radicals, highly reactive molecules that can damage tissues and lead to cancer and heart disease. Although the body has several ways of coping with free radicals, many people believe high doses of vitamins help, mopping up free radicals before they can do much damage.
