Liver Damage from Supplements on the Rise

Herbal and dietary supplements now account for 20% of all reported hepatotoxicity cases in the United States. This is up from 7% in 2004-2005. Anabolic steroids included in dietary supplements marketed for bodybuilding accounted for over 30% of these liver damage cases. Among the non-anabolic steroid products most commonly associated with liver damage were herbal products (16%), such as green teakratom, and black cohosh; traditional botanical mixtures (8%), such as ayurvedic medications; vitamins and minerals (7%), such as niacin and multivitamins; and other multi-ingredient nutritional supplements (68%).
