Asymmetric Dimethylarginine (ADMA) is a naturally occurring compound in the body that is produced during the metabolism of arginine, an amino acid. It is known to inhibit the production of nitric oxide, a vital molecule that helps regulate blood flow and maintain cardiovascular health. Elevated levels of ADMA can lead to reduced nitric oxide availability, which may contribute to various cardiovascular diseases. ADMA is often measured in blood tests as a potential biomarker for cardiovascular risk. High levels of ADMA have been associated with conditions such as hypertension, atherosclerosis, and diabetes. Understanding ADMA's role in the body can help researchers develop new strategies for preventing and treating these health issues.
