The fact that the human body converts 70–80 percent of caffeine into paraxanthine with no apparent toxic effects following caffeine doses of 300– 500 mg/day suggests that paraxanthine’s toxicological potency is low. Formation of paraxanthine and its excretion in the urine appears to be the major pathway for caffeine metabolism (Stavric, 1988). Hetzler et al. (1990) demonstrated that lipolytic effects of caffeine may be due to the action of paraxanthine rather than caffeine itself. Increasing concentration of plasma-free fatty acids following intravenous administration of caffeine was negatively correlated to plasma caffeine concentrations, and highly positively correlated to plasma paraxanthine concentrations.
