- What is l-arginine?
l-Arginine is an amino acid, important in muscle metabolism and the formation of nitric oxide (NO) in the body.
- What is L-citrulline?
All your cells use ATP molecules for energy. Your muscles use ATP for energy and in turn, produce IMP (inosine monophosphate, a nucleoside), lactic acid and ammonia. These byproducts of exercise accumulate and cause muscle fatigue. l-Citrulline supports muscle recovery after exercise, helping clear ammonia from the liver and converting it to urea for excretion. This enables the muscles to recover after exercise.
- Why are the two amino acids available in one supplement?
We’ve combined these two amino acids to provide a more convenient performance-enhancing product for athletes. During intense exercise there is an increased production of ammonia in the exercised muscle. l-Arginine & l-Citrulline from Source Naturals supports metabolism, protein synthesis and liver detoxification. The l-arginine supports nitric oxide (NO) production, beneficial to the heart and blood vessels, while the l-citrulline supports detoxification of ATP metabolism byproducts beneficial for post-workout recovery.
