L-arginine and L-citrulline are amino acids with important functions in the body, including the production of nitric oxide and the elimination of metabolic waste products following exercise.
- Arginine and citrulline are two amino acids essential for protein metabolism, as well as for the maintenance of muscle tissue.
- Both are key intermediates in the urea cycle, where they participate in the detoxification of ammonia through the production of urea
- In addition, any arginine not converted to urea enters the general bloodstream, where it is distributed to various tissues and metabolized for other purposes, such as protein synthesis.
- Arginine is necessary for the production of nitric oxide. L-arginine supplements can improve physical performance by increasing nitric oxide levels in the body, which improves blood circulation and oxygenation of the muscles.
- After citrulline is consumed, some of it is converted into another amino acid called arginine.
