Now Foods L-Arginine 500mg 100caps

L-arginine is a conditionally essential amino acid that is primarily involved in the metabolism and excretion of urea as well as DNA synthesis. L-arginine is important for the production of growth hormone (stimulating the pituitary gland), the production of sperm (participating in sperm and semen), the improvement of a person's sensitivity to insulin, the improvement of muscle tone, the healing of wounds (stimulating the collagen formation) and to maintain healthy blood pressure levels as a means of producing nitric oxide.

Arginine is the primary ingredient used as a base for the formation of nitric oxide. Whenever the body activates the enzyme nitric oxide synthase to convert excess arginine to citrulline (another amino acid) then nitric oxide is produced.

This activity occurs mainly in the liver. L-arginine supplementation is often necessary. For example, people with protein malnutrition or excessive lysine intake or with burns and possible infections may need arginine intake. Symptoms of arginine deficiency include poor wound healing, hair loss, rashes, constipation and fatty liver.

Suggested Use: As a dietary supplement take 2 capsules 1-3 times daily as required.
