Arginine is a nonessential amino acid, it can be manufactured by the human body. The biosynthetic pathway, however, does not produce sufficient arginine, and some must still be consumed through diet. Arginine is found in a wide variety of foods such as dairy, meat, poultry and seafood. Plant sources includes, Grains, Beans & nuts. (Pea protein isolate has the highest source of Arginine at 8.7%).
Arginine plays an important role in cell division, the healing of wounds, removing ammonia from the body, immune function, and the release of hormones.
The benefits and functions attributed to oral supplementation of L-arginine include:
Precursor for the synthesis of nitric oxide (NO). Reduces healing time of injuries (particularly bone).Quickens repair time of damaged tissue. Helps decrease blood pressure in clinical hypertensive subjects. It is used by athletes to increase oxygen delivery and blood flow during exercise, arginine causes vasodilation by stimulating the smooth muscle endothelial cells that line the blood vessels to produce a compound called nitric oxide. Nitric oxide stimulates blood vessels to relax and expand, increasing the flow of blood and oxygen to the muscles during bouts of intense exercise, especially resistance training. An increase in blood flow and oxygen delivery during exercise may enhance performance, allowing muscles to produce more strength and delaying the onset of exercise-induced fatigue.*
Dosage; This varies very widely depending on conditions being addressed. For sport nutrition, 6-12g/day is recommended. Consult your healthcare provider for proper dosage for other purposes.
