Doctor’s Best L-Citrulline is a well-studied amino acid precursor to L-Arginine which is responsible for building muscle and supports nitric oxide (NO) production, a key molecule involved in a variety of essential biological functions throughout the body, particularly in supporting the regulation of vascular tone and improving blood oxygenation for improved stamina and recovery from exertion.
L-Citrulline, commonly found in founds such as watermelon, cucumbers and squash, is one of three dietary amino acids involved in the urea cycle that detoxifies ammonia by converting it to urea for excretion from the body. It’s also a natural precursor to the amino acid L-Arginine, which is poorly available for cells in the body as a significant portion is broken down in the intestines before it reaches the circulation. Research has shown that L-Citrulline is more effective than L-Arginine in raising circulating L-Arginine levels because it is able to bypass metabolism in the gastrointestinal tract and liver.
L-Citrulline is able to raise levels of L-Arginine in the body which is an essential precursor for the body’s natural muscle building process. It also supports muscle fatigue recovery through the elimination of ammonia. L-Citrulline plays an important role through its conversion and support of L-Arginine in the regulation and metabolism of nitric oxide (NO) in the body. Increased nitric oxide promotes the dilation of blood vessels which improves blood flow, and the degree of oxygenation available to cells throughout the body.
