L-Arginine

Sustained-release L-arginine supports cardiovascular function, wound healing, and immune function – and is a biological precursor to nitric oxide. L-arginine is a semi-essential amino acid involved in multiple areas of human physiology and metabolism. L-arginine significantly affects endocrine function and helps regulate the release of neurotransmitter chemicals, insulin, glucagon (which has the opposite effect of insulin; i.e., it raises blood sugar), and growth hormone. However, one of L-arginine's most compelling contributions to human physiology is its role as a biological precursor of nitric oxide. The vascular endothelium (lining of the arteries) creates nitric oxide from L-arginine, resulting primarily in blood vessel relaxation. This property is critical to maintaining good vascular health, heart health, reproductive health, and protection against oxidative damage.

Like most amino acids, L-arginine functions as a building block of proteins; however, its presence also appears to support wound healing. Numerous studies show L-arginine supplementation benefits wound healing time and strength of the tissue in and around the wound during the healing phase.

L-arginine is absorbed and metabolized by the body very quickly, which usually necessitates taking it frequently throughout the day. Sustained-release L-Arginine, however, maintains an optimal level of L-arginine over 24 hours with suggested twice-daily use.

When sufficient L-arginine is present:

•Arteries relax, promoting optimal blood flow
•As arteries relax, already normal blood pressure can be better maintained
•Erections occur in the normal course of intimacy
•Supple, flexible arteries are better able to support good cardiovascular health
