Arginine is an amino acid that is a precursor of nitric oxide in the body. Nitric oxide causes vasodilatation and relaxes muscle tissue. Arginine Malate is a non-polar form of Arginine that is rapidly absorbed in the body. It is also much more stable than regular L-Arginine. Because of the increased absorption and stability Arginine Malate can raise nitric oxide levels to a greater degree than regular L-arginine supplements. Helps remove waste from Body What is L-Arginine L-arginine is an amino acid that has numerous functions in the body. It helps the body get rid of ammonia a waste product, is used to make compounds in the body such creatine, L-glutamate, and L-proline, and can be converted to glucose and glycogen if needed. L-arginine is used to make the nitric oxide, a compound in the body that relaxes blood vessels. Preliminary studies have found that L-arginine may help with conditions that improve when blood vessels are relaxed called vasodilation Sources of L-Arginine L-arginin
