Large new study: Mutivitamins & supplements don't help & may be harmful

Multivitamins and many other dietary supplements provide little benefit for most people and may be harmful, according to researchers behind a large new study.

The researchers tracked nearly 39,000 women for an average of 19 years. They found a small increase in the risk of death among older women who took dietary supplements compared with those who didn't, according to the study, released Monday in the Archives of Internal Medicine. 

An exception was calcium supplements, which are widely recommended to protect against bone fractures. They were associated with a slightly decreased risk of premature death.
