Arginine and Ornithine have been a popular and effective combination for decades. This combination of essential amino acids provides several important benefits, such as stimulating GH release which promotes muscle growth, playing a key role in the removal of excess ammonia which is a toxic byproduct of protein metabolism, and promoting nitric oxide production – your body not only uses arginine to produce nitric oxide, it uses ornithine to convert to arginine which stimulates even more production of nitric oxide – this means better pumps and enhanced nutrient delivery to your working muscles.

Arginine and Ornithine by NOW provides a 2:1 ratio of arginine to ornithine in a fast-acting capsule delivery format. You can depend on the quality of NOW products – pick up a bottle today and see for yourself!
