Ornithine, Proline and Serine
Nonessential Amino Acids

Ornithine helps to prompt the release of growth hormones. While Proline improves skin texture and Serine is needed for proper metabolism of fats and fatty acids.

The fact that they are termed "nonessential" does not mean that they are not necessary, only that they need not be obtained through the diet because the body can manufacture them as needed.

Ornithine: helps to prompt the release of growth hormones, which promotes the metabolism of excess body fat. This effect is enhanced if ornithine is combined with arginine and carnitine.

Ornithine is necessary for proper immune system and liver function. This amino acid also detoxifies ammonia and aids in liver regeneration. High concentrations of ornithine are found in the skin and connective tissue, making it useful for promoting healing and repairing damaged tissues.

Orthithine is synthesized in the body from arginine, and in turn serves as the precursor of citrulline, proline, and glutamic acid.

Caution: Supplemental L-ornithine should not be taken by children, pregnant women, nursing mothers, or anyone with a history of schizophrenia, unless they are specifically directed to do so by a physician.


Proline improves skin texture by aiding in the production of collagen and reducing the loss of collagen through aging process.

Proline also helps in healing cartilage and the strengthening of joints, tendons, and heart muscles. It works with vitamin C to promote healthy connective tissue.

Proline is obtained primarily from meat sources.


Serine is needed for the proper metabolism of fats and fatty acids, the growth of muscle, and the maintenance of a healthy immune system. It aids in the production of immunoglobulins and antibodies.

Serine can be synthesized from glycine in the body. It is included as a natural moisturizing agent in many cosmetics and skin care preparations.
