L-Ornithine is an amino acid closely linked to L-arginine. Ornithine supplements are mostly used to:
What is L-Ornithine?
L-Ornithine is an amino acid involved in the urea cycle, which helps to remove ammonia and excess nitrogen from the body. It is metabolized into L-arginine and carries many of the same biological qualities as that prominent amino acid. Like arginine, ornithine is associated with maintaining optimal vascular health.**
Research has indicated that L-ornithine assists in modulating the metabolism of lipids (fats) and other amino acids (proteins), and this attribute may support exercise performance and physical endurance. When combined with arginine in a supplementation study, the nutrient elevated levels of growth hormones in the body after subjects underwent heavy-resistance training, showing a potential connection to muscle building. Further investigations have noted that the amino acid may aid in wound healing and may support liver wellness.**
L-Ornithine is present in meat, fish, eggs and dairy, and consuming these foods can increase levels of the amino acid in the body. Available in capsule, caplet and powder form, ornithine supplements may be offered in vegan, vegetarian and gluten-free varieties. Supplements of the amino acid often also feature L-arginine and are geared towards bodybuilders. These products supply therapeutic levels that are higher than dietary amounts alone.**
L-Orthinine Directions for Use
Talk to your health care professional before taking this nutrient or starting any regular supplementation. Although there is no set suggested amount, capsule doses are often 500 mg.**
