Ornithine is a non-essential amino acid that plays a central role in the urea cycle, functioning along with Arginine and Citrulline to rid the body of ammonia, a byproduct of protein metabolism. Because Ornithine is converted into Arginine, it can help to maintain healthy Arginine levels in the body. Ornithine can also be converted into other amino acids, such as citrulline, proline, and glutamate, as well as creatine, an important muscular energy source.

Suggested Use

Take 1/2 teaspoon 1 to 2 times daily, mixed with juice or water, on an empty stomach.

Other Ingredients


Not manufactured with yeast, wheat, gluten, corn, soy, milk, egg, fish, shellfish, or tree nut ingredients. Produced in a GMP facility that processes other ingredients containing these allergens.
