Supplement may add diabetes risk

July 14, 2007|From Times Staff and Wire Reports

Selenium dietary supplements may raise a person's risk of developing diabetes, not lower it as had been suspected, researchers reported Monday in the Annals of Internal Medicine.

People who took a 200-microgram daily dose of the mineral for seven years had a 50% higher risk of developing type 2 diabetes compared with the placebo, the study found. About 60% of Americans take multivitamins, most of which include 33 to 200 micrograms of selenium. In the U.S., the recommended dietary allowance for healthy adults is a minimum of 55 micrograms.
