- How is that done?
During intense exercise muscles produce and accumulate lactic acid and ammonia which cause muscle fatigue. l-Citrulline supports the healthy metabolic processing of ammonia, helping the muscles recover from fatigue. Ammonia, lactic acid and IMP (inosine monophosphate) a nucleoside, are produced during intense exercise, when the body calls upon ATP (adenosine triphosphate) for continued energy. These accumulate and establish muscle fatigue.
