Ornithine
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
