0.18g/kg citrulline supplementation daily for a week (without exercise) failed to significantly influence plasma IGF-1 or insulin and did not affect muscle protein synthesis rates. A 13% decrease in glutamine concentrations in serum was noted.

Supplementation of 6g citrulline prior to a prolonged exercise test was associated with an increase in urea (27.1-30.4%) and nitrite (indicative of nitric oxide) and appeared to attenuate the rise in urate. Growth hormone increased 66.8% after exercise

この研究の注釈：

In an incline walking test until failure in otherwise healthy persons, 3 or 9g citrulline (acutely or over 24 hours, respectively) appeared to actually reduce time to exhaustion (0.8%, a clinically irrelevant degree) and suppressed the exercise-induced increase in insulin. Other biomarkers tested were unaltered, although heart rate trended to decrease with 3g citrulline
