Vitamins related to higher death risk in women
When it comes to vitamins, looks like it could be too much of something good, say researchers who reported a relationship between use and higher rates of mortality among older women.

Experts have suspected for some time that supplements can only be beneficial if a person has a nutrient deficiency.

And the excess can even harm as the study in Archives of Internal Medicine found.

All women, 50 and 60, were generally well fed, but many have decided to take supplements.
