Ornithine
Uses
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).
How It Works
How to Use It
Most people would not benefit from ornithine supplementation. In human research involving ornithine, 5–10 grams are typically used per day, sometimes combined with arginine.
Where to Find It
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.
Possible Deficiencies
Since ornithine is produced by the body, a deficiency of this nonessential amino acid is unlikely, though depletion can occur during growth or pregnancy, and after severe trauma or malnutrition.1
Interactions
Interactions with Supplements, Foods, & Other Compounds
The presence of arginine is needed to produce ornithine in the body, so higher levels of this amino acid should increase ornithine production.
Interactions with Medicines
Side Effects
Side Effects
Gastrointestinal distress has been reported with intakes over 10 grams of ornithine per day.
