title: Acne and whey protein supplementation among bodybuilders.
abstract: Accumulative evidence supports the role of nutritional factors in acne. I report here 5 healthy male adult patients developing acne after the consumption of whey protein, a favorite supplement of those engaged in bodybuilding. These observations are in line with biochemical and epidemiological data supporting the effects of milk and dairy products as enhancers of insulin/insulin-like growth factor 1 signaling and acne aggravation. Further prospective studies are required to determine the possible role of dietary supplements in the fitness and bodybuilding environment.
