L-Arginine is a semi-essential amino acid involved in numerous areas of human biochemistry including ammonia detoxification, hormone secretion and immune modulation. Although amino acids can be manufactured by the human body, the biosynthetic pathway does not produce sufficient amounts and some must still be obtained through the diet. It is found in a large number of plant and animal sources, including wheat germ, nuts, seeds, dairy products, beef, pork, poultry and seafood. Individuals with poor nutrition or certain physical conditions might be advised to increase their intake of foods containing L-Arginine or by taking L-Arginine supplements.

L-Arginine supplements for cardiovascular health

L-Arginine is also well-known as the immediate precursor to nitric oxide (NO), the endothelium-derived relaxing factor, and as an endogenous messenger molecule involved in various different endothelium-dependent physiological effects in the cardiovascular system. The endothelium (inner lining) of the blood vessels uses NO to signal the surrounding smooth muscle to relax, thus resulting in vasodilation and increased blood flow. NO is also involved in inhibiting platelet aggregation and leukocyte adhesion to the endothelium.

L-Arginine supplements to strengthen the immune system

There is strong evidence that L-Arginine supplements help to strengthen the immune system in adults in humans and in animal models.

L-Arginine-derived nitric oxide plays a major role in inflammation and immunity.

L-Arginine supplements and connective tissue and bones

Found in high concentrations in the connective tissues, L-Arginine is a component of collagen, which plays a crucial role in the production and renewal of new or damaged tissue and bone cells. Surgery or injury greatly increases the body´s L-Arginine requirements, which can be met with L-Arginine supplements.


While L-Arginine is a precursor to nitric oxide, which the body uses to keep blood vessels dilated, increasing blood flow and allowing the heart to receive adequate oxygen, it should not be used following a heart attack. If you have a history of heart disease, consult your doctor before taking L-Arginine.
