Plasma concentrations of citrulline, arginine, ornithine, and leucine in the fasted state and during sip ingestions of citrulline in the kinetic study. There were no significant age-by-time interactions for citrulline, arginine, and ornithine. However, there were significant differences with respect to time for arginine and citrulline (for all, P < 0.0001; for ornithine P = 0.0203) and with respect to age only for ornithine (P = 0.0280). Data are presented as means ± SE.
