This herbal supplement includes a natural component of rice bran, maize, and barley oils – Gamma Oryzanol. Some evidence suggests that Gamma Oryzanol increases testosterone levels, stimulates the release of endorphins (pain relieving substances made in the body) and promotes the growth of lean muscle tissue. Gamma Oryzanol is a naturally occurring antioxidant shown in research to support equine health and performance.
