Chemical Structure:

L-Ornithine is an amino acid and used in the body in the biosynthesis of L-arginine; L-proline and polyamines. L-Ornithine is used as a nutritional supplement principally for its putative anabolic activity.

L-Ornithine also helps remove toxic ammonia from the liver, and may reduce the effects of cirrhosis of the liver and disorders associated with liver malfunction. L-Ornithine increases both insulin and growth hormone levels, which are needed to build and maintain muscle during intensive physical training.

L-Ornithine helps combat the muscle loss that is a normal part of the aging process. By elevating growth hormone levels, ornithine can help speed the production of muscle tissue and offset the effects of aging. Although both arginine and ornithine help protect and build muscle
mass, ornithine is generally twice more effective at stimulating growth hormone production than arginine.

Benefits of L-Ornithine in liver:
• L-ornithine improves impaired ammonia detoxification and regulates urea cycle.

Other Benefits of L-Ornithine:
• L-Ornithine is known to be crucial for the metabolism of keratinocytes especially in the synthesis of urea, polyamines and precursors of collagen synthesis.

• L-Ornithine may at very high doses around 30 grams stimulates the
pituitary release of growth hormone.

Clinical Evidence
• L-Ornithinie increases metabolism of fat & improves ammonia detoxification & regulates urea cycle.
