L-Arginine 1000mg | Nitric Oxide and Circulation Support

L-arginine is a semi-essential amino acid and the direct substrate for nitric oxide synthase (NOS) the enzyme that produces nitric oxide in the body. Nitric oxide is a potent vasodilator that relaxes vascular smooth muscle, supporting healthy blood vessel tone and circulation. L-arginine supplementation supports nitric oxide production, healthy circulation, and exercise performance. Consult a healthcare practitioner before use if you are taking medications for cardiovascular conditions, blood pressure, or erectile dysfunction, or if you are pregnant or breastfeeding.

L-arginine is converted to nitric oxide (NO) and L-citrulline by nitric oxide synthase (NOS) enzymes, using oxygen as a co-substrate. Endothelial nitric oxide synthase (eNOS) the primary NOS enzyme in blood vessel walls uses L-arginine to produce NO that regulates local blood flow and vascular function. Nitric oxide acts as a gaseous signaling molecule that relaxes vascular smooth muscle, reduces vascular resistance, and supports healthy blood vessel tone and circulation. By providing L-arginine as substrate, supplementation supports the body's endogenous nitric oxide production pathway.

Free form means the amino acid is not bound to a protein chain and is available for direct absorption in the small intestine no digestion of a protein is required before absorption. L-arginine HCl (monohydrochloride) is the hydrochloride salt form of L-arginine, which provides stability and consistent potency. Free form L-arginine HCl is the pharmaceutical-grade form used in clinical research and supplement formulation, produced by fermentation of plant-based substrates.

L-arginine supports exercise performance through nitric oxide mediated vasodilation increased blood flow to working muscles supports oxygen and nutrient delivery during exercise and waste product removal during recovery. L-arginine is commonly used as a pre workout supplement for this reason. Consult a healthcare practitioner before use if you have a cardiovascular condition and are attempting an increase in physical activity.

Do not use L-arginine if you have an active herpes simplex virus infection L-arginine may promote viral replication. Consult a healthcare practitioner before use if you are taking medications for cardiovascular conditions, blood pressure, or erectile dysfunction, or if you are pregnant or breastfeeding. High doses may cause gastrointestinal discomfort in some individuals. Keep out of reach of children.

Consult a healthcare practitioner before use if you are taking blood pressure medications. L-arginine supports nitric oxide production and vasodilation, which may have additive blood pressure lowering effects when combined with antihypertensive medications. Do not self supplement with L-arginine if you are on blood pressure medications without professional guidance and monitoring.
