Athletic men show no benefits from L-arginine

L-arginine is one of the most recent, popular supplements for athletes looking to boost performance. It can increase growth hormone response, and so can increase muscle mass. Also it has an impact on insulin, which is another anabolic hormone. L-arginine is also often prescribed for older adults with cardiovascular disease, endothelial dysfunction or hypertension for its vasodilation properties and is rarely studied in younger, more vigorous populations.

Acccording to one of the most recent study, it appears that L-arginine’s impact depends on one’s current health status: the more healthy and athletic the person, the less they’ll benefit from it.
