Nutritional Supplement Features:

Amino acids are used by the body to build proteins. Proteins are essential for the formation of cells and are also involved in the biochemical structure of hormones, enzymes, neurotransmitters and antibodies.

L-Arginine is essential in muscle metabolism because it provides a vehicle for transport, storage and excretion of nitrogen.

L-Arginine is an important component in tissue generation and regeneration.

L-Arginine is highly concentrated in the skin and connective tissue and helps to remove ammonia from the body as part of the urea cycle.

L-Arginine can be very helpful in cases of burns, trauma and sepsis.

L-arginine has been shown to have immunomodulatory activity. For example, in human breast cancer, supplementation with this amino acid has been reported to increase the quantity and cytotoxic activity of natural killer (NK) cells and lymphokine-activated-killer (LAK) cells.

L-arginine's possible activity in wound repair may be due to its precursor role in the formation of L-ornithine and, ultimately, L-proline. L-proline is a key element in collagen biosynthesis.

There is preliminary evidence that L-arginine could be helpful in some men with erectile dysfunction.

L-arginine has been shown to be helpful in reducing cholesterol and high blood pressure. It has also been helpful in those with angina pectoris.

Several studies have found that L-arginine can help with interstitial cystitis. Other studies, however, have not reported benefit. It appears that L-arginine can decrease pain and urgency in some people with interstial cystitis, but more research is needed to confirm this.

Ornithine releases growth hormone and helps maintain the health of the immune system and the liver. It has similar properties to arginine since these two amino acids convert into one another in the body, as required.
