Urinary excretion of catecholamines and cortisol was examined in 26 healthy male volunteers (ages 20-27) on different vitamin C intakes to discern differences in response to a standardized stress. The high-dose vitamin C group (3 g/day vitamin C) excreted more adrenaline that the low vitamin C intake group, suggesting a further role for vitamin C in catecholamine biosynthesis (in addition to serving as a enzymic cofactor), and in the biochemical response to stress. Urinary levels of other catecholamines studied (dopamine, noradrenaline) and of cortisol were similar between the two groups. (wz)
