Q: What’s your opinion on taking a selenium supplement? I’ve been taking one for years, but now I’m hearing that it might not be such a good thing. — M.C., Wilkes-Barre, Pa.

One study published in the Aug. 21 issue of the Annals of Internal Medicine showed that people receiving 200 micrograms of selenium daily might have a higher incidence of diabetes.
