Ornithine is claimed to stimulate the immune system, improve liver function and promote healing by stimulating production of collagen. It is also believed to stimulate output of hormones, particularly human growth hormone (HGH).
Ornithine may play a role in increasing muscle mass and decreasing body fat.
Amino acids (AAs) are available as individual AAs or in proprietary AA combinations, as well as part of multi-vitamin formulas, proteins and food supplements. The forms include tablets, fluids and powders. However, adequate protein in the diet should provide a sufficient source of all amino acids.
There are no conditions that increase the requirements for ornithine.
Side Effects, Toxicity and Interactions:
The use of a single amino acid supplement may lead to a negative nitrogen balance, decreasing metabolic efficiency and increasing the workload in the kidneys. In children, taking single amino acid supplements may also harmfully affect growth parameters.
Always avoid taking individual amino acids in high dosage for prolonged periods.
Women who are pregnant or breast-feeding should not use ornithine supplements. Pre-pubescent children should also not use this supplement.
Individuals diagnosed with schizophrenia should avoid ornithine.
