Buy Brand-Name Supplements

(HealthDayNews) -- If you take supplements, choose brands from major pharmaceutical houses, advises Duke University.

Because supplements aren't regulated by the U.S. government, you may not be getting the quantity or quality of active ingredients touted on the label. Also, there have been cases where supplements have been contaminated, which could cause a range of health problems.

By sticking with major manufacturers, you improve your chances of getting quality products.
