Ornithine
What is Ornithine?
Ornithine is a non-essential amino acid and is manufactured by the body, the amino acid, arginine, is metabolized during urea production and is required by the body as it acts as a precursor of citrulline, proline and glutamic acid.
What it does?
Ornithine, an amino acid, is manufactured by the body when another amino acid, arginine, is metabolized during the production of urea (a constituent of urine). Animal research has suggested that ornithine, along with arginine, may promote muscle-building activity in the body by increasing levels of anabolic (growth-promoting) hormones such as insulin and growth hormone. However, most human research does not support these claims at reasonable intake levels.
Deficiency of ornithine
Since the body can produce ornithine, a deficiency of this non-essential amino acid is rare.
Where is it found?
As with amino acids in general, ornithine is predominantly found in meat, fish, dairy, and eggs. Western diets typically provide 5 grams per day. The body also produces ornithine.
When more may be required
People recouping after surgery and athletes may benefit from this nutrient.
Are there any side effects or interactions?
No side effects have been reported with the use of ornithine, except for gastrointestinal distress with intakes over 10 grams per day.
