L-citrulline is a naturally occurring amino acid. It is found in some foods like watermelons and is also produced naturally by the body.

L-citrulline is used for Alzheimer’s disease, dementia, fatigue, muscle weakness, sickle cell disease, erectile dysfunction, high blood pressure, detoxification and diabetes. It is used for heart disease, body building, increasing energy, and for improving athletic performance (exercise recovery).

L-citrulline is a naturally occurring amino acid found in food, such as watermelons, and also made in the body. Our bodies change L-citrulline into another amino acid called L-arginine and also to nitric oxide. L-citrulline might help increase the supply of ingredients the body needs to making certain proteins. It might also help open up veins and arteries to improve blood flow and reduce blood pressure.

Citrulline, an amino acid, occurs naturally and aids in the body’s urea cycle, the process that clears ammonia – a byproduct of normal metabolism – out of one’s system.

Physicians can prescribe these supplements — sold as tablets, capsules, liquids and powders – to help treat certain genetic disorders and a variety of other illnesses. Without a prescription, consumers can take over-the-counter versions of the supplements. The most common over-the-counter users today are bodybuilders and athletes who want to boost their endurance.

Other purported benefits include increased energy, enhanced circulation and improved immune system function. Scientific evidence to either confirm or refute these claims is lacking, with the few small studies that have been done producing conflicting results.

Treatment for certain urea cycle disorders is arguably the most important use of L-citrulline. These rare conditions cause a deficiency of enzymes, mostly in children. Because these enzymes remove ammonia from the bloodstream, a lack of them can cause a buildup of ammonia.
