Liver istockA popular diet supplement has caused an outbreak of severe liver disease, sickening nearly 100 people in 16 states since it was first reported in Hawaii last year, according to a new paper. The publication calls for a better system to remove dangerous supplements from the market. As of February, OxyElite Pro, a dietary supplement manufactured by USPLabs that claims to help people burn fat, has been linked to 97 cases of hepatitis, including 47 people who were hospitalized, three who needed liver transplantations and one person who died, according to the paper, which was authored by Dr. Pieter Cohen, an assistant professor of medicine at Harvard Medical School and a general internist at Cambridge Health Alliance. Although people who took the supplement started getting ill in May last year, the Food and Drug Administration did not learn of the cases until four months later, in September, when doctors reported a cluster of liver illnesses in Hawaii. USPLabs stopped selling the product in October. More
