Di-Arginine Malate:

Di-Arginine Malate is the most readily absorbed form of L-Arginine available.  In general, Arginine helps prevent muscle loss and also helps in the restoration of lost muscle tissue.  It works as a building block for creatine which horses use to build and maintain healthy, strong muscles.  It also increases nitric oxide (NO) which helps keep endothelial cells healthy.  Without nitric oxide, blood vessels become constricted and less flexible.  Blood vessel dilation increases significantly with L-Arginine supplements and this dilation aids in the transport of essential nutritional compounds and also aids in lactic acid clearance.

Gastric ulcers affect more than 80-90% of race horses and 60% of show horses, hunter-jumpers and recreational horses.  Gastric ulcers are believed to be caused by the stress and intense exercise and the damaging effects of excess stomach acid.  It is known that nitric oxide promotes the healing process of gastric ulcers and helps prevents the ulcers from forming in the first place.  As L-Arginine increases nitric oxide production, it also aids in the healing of existing ulcers and can help prevent them from forming as well.
