NOW L-Ornithine is a non essential amino acid which together with arginine is part of the urea-cycle. NOW makes its products as much as possible from natural free form amino acids, for optimal absorption and operation. L-Ornithine can be used directly and does not need to be converted first. The body is able however to convert Ornithine in arginine, proline, citruline, glutamine and creatine.
NOW L-Ornithine is a high quality product with a free form of Ornithine. Amino acids are the building blocks of protein and therefore most body tissues. Suitable for daily use.
