Ornithine is an amino acid that forms other amino acids namely, citrulline, glutamic acid, and proline. These three are responsible for supplying energy to every cell in the body. The body can produce ornithine from arginine, but dietary sources provide an additional source to support required levels
Ornithine helps to build muscles, promotes tissue repair, reduces body fat and fights off the signs of aging. This is done by the role it plays in stimulating growth hormone production. Growth hormones are needed to build and maintain muscle, especially during intense physical training.
Ornithine enhances fat metabolism, regulates salt levels in the body and supports healthy sexual function. It is also vital for removing toxic ammonia from the liver as well as excess nitrogen content in the body.
Ornithine is a non-essential amino acid meaning that the body can produce the supply that is needed however, it may help to consume foods rich in this amino acid when in training for physical sports.
