Some Supplements That Claim to Burn Fat Contain Unapproved Stimulant Drug

An analysis of sports supplements that claim to burn fat or improve your workout may contain a stimulant drug banned by the World Anti-Doping Agency. Researchers from Harvard Medical School say the stimulant may pose health risks.

The stimulant drug is oxilofrine, also known as methylsynephrine or p-hydroxyephedrine. Researcher Pieter Cohen told NPR that oxilofrine can stimulate the heart and has some medical uses, such as boosting heart function in patients under anesthesia.

Oxilofrine is not supposed to be in dietary supplements, which by law are supposed to contain only “dietary ingredients,” the article notes. The Food and Drug Administration (FDA) has stated oxilofrine does not meet the definition of a dietary ingredient.
