L-Citrulline
Citrulline is an amino acid. Its name is derived from
citrullus, the Latin word for watermelon, from which it was first isolated in 1914.
It is a key intermediate in the urea cycle, the pathway by which mammals excrete ammonia. In man,
citrulline is produced as a byproduct of the enzymatic production of nitric oxide from the amino acid
arginine, an essential reaction as nitric oxide is a vasoldilator involved in regulating blood pressure.
It has been suggested (the evidence is weak - single
study, second tier journal, no confirmatory studies) that watermelon may decrease post exercise muscle
soreness and the active agent is L-citrulline. A second study
on citrulline maleate (as a supplement) supported that finding in resistance exercise (weight lifters).
