L-Arginine, 2,4-thiazolidinedicarboxylate (1:1) is primarily used in the pharmaceutical and nutraceutical industries. It serves as a key component in formulations aimed at improving cardiovascular health, as it helps in the production of nitric oxide, which relaxes blood vessels and enhances blood flow. This compound is also utilized in dietary supplements to support muscle growth and recovery, particularly in athletes and bodybuilders, due to its role in protein synthesis. Additionally, it is incorporated into treatments for conditions like hypertension and erectile dysfunction, leveraging its vasodilatory properties. Its antioxidant characteristics further make it valuable in combating oxidative stress and promoting overall cellular health.
