What is L-Citrulline?

L-Citrulline is an amino acid created and used by the body and found in certain foods, including watermelon. The compound influences other amino acids and is crucial to metabolizing and utilizing protein. The amino acid also functions as a natural precursor of L-Arginine, in turn aiding the production of nitric oxide (NO), which facilitates various key biological processes such as circulation and respiration. With these core biological actions, L-Citrulline has become popular as a sports nutrition supplement for performance-oriented athletes.**

Further supporting its role as a sports nutrient, research has shown that supplemental intake of L-Citrulline elevates L-Arginine concentration in the bloodstream and bolsters nitric oxide-dependent signaling. This ability is believed to allow the amino acid to optimize exercise, with studies pointing to benefits for physical performance and recovery. It appears to enhance the body’s usage of branched-chain amino acids (BCAAs) during exercise, potentially assisting bodybuilders and athletes who favor BCAA supplementation during training. Investigations have also indicated that L-Citrulline supports muscle energy metabolism, specifically protein synthesis in muscle, which may hold potential for supporting peak physical performance and healthy aging.**

Scientific findings have additionally suggested the importance of L-Citrulline's key roles in respiration and circulation. The amino acid has been linked to the relaxation of airways for more efficient and full breathing, a property tied to its promotion of nitric oxide production. Similarly, the compound's NO-related qualities also help maintain healthy cardiovascular function by relaxing arteries and veins for ideal blood flow, a trait which may in turn benefit men's reproductive wellness. The compound has been studied in recent years for its ability to promote healthy sexual function in men. It also plays an integral role in the urea cycle, helping to cleanse the body via the liver by disposing of the waste product ammonia.**

L-Citrulline Supplements

L-Citrulline supplement products are available as capsules and tablets, as well as in powder form. The nutrient is sometimes paired with L-Arginine in exercise and training-oriented sports nutrition formulas.**

L-Citrulline Directions for Use

It is important consult with your physician before starting any regular supplementation. Though no suggested dosage has been established, standard L-Citrulline dosage in capsules and tablets ranges between 500 mg and 1,000 mg.**
