L-Arginine FAQs

Overview

Arginine, also known as L-arginine, is an amino acid that is a building block for proteins. Arginine is naturally produced in the body and can be found in various foods like red meat, poultry, fish, dairy products, eggs, and seeds. One of its key functions is promoting the dilation or opening of blood vessels. This occurs when arginine is converted into nitric oxide, which relaxes the muscles that constrict blood vessels. Arginine is available as a pharmaceutical supplement and is used to treat various conditions. It can stimulate the release of insulin, growth hormone (which aids in muscle growth and fat reduction), and other substances.

Benefits of L-Arginine

In addition to its role in blood vessel dilation, L-arginine may offer benefits in several areas, including improving athletic performance, supporting kidney function after a transplant, managing preeclampsia (a pregnancy-related condition), alleviating inflammation in the digestive tract of premature infants and enhancing immune system function. When applied topically, L-arginine aids in wound healing, improves blood flow to cold hands and feet (particularly useful for individuals with diabetes) and addresses sexual issues in both men and women.
