L‑Arginine is an amino acid that helps the body produce proteins. It is classified as a semi‑essential amino acid, meaning that under certain conditions the body cannot produce sufficient amounts to meet its needs, and it must therefore be obtained from dietary sources or supplements.
L‑Arginine is considered an essential amino acid for children and for individuals with certain genetic disorders that impair the body’s ability to produce this amino acid.
Because L‑Arginine acts as a vasodilator, helping to relax and widen blood vessels, it is commonly used to support cardiovascular health and improve blood circulation, and it may also help in the management of erectile dysfunction. In addition, L‑Arginine stimulates the release of growth hormone and serves as a precursor to nitric oxide, creatine, and tetrapeptides.
Evidence suggests that L‑Arginine supplementation may help improve certain forms of male sexual dysfunction. It also plays a positive role in regulating and balancing the immune system. Due to its role in protein synthesis, L‑Arginine may also support athletic performance, muscle strength, and increased muscle mass.
Preeclampsia, or high blood pressure during pregnancy, is a potentially serious condition that can affect both mother and fetus. L‑Arginine supplementation may help reduce high blood pressure in pregnant women and support healthy fetal growth in women affected by preeclampsia.
