Caffeine is a methylxanthine alkaloid naturally found in various plant parts that acts as an antagonist at central adenosine receptors at relevant physiological concentrations (IC50 = ~30 μM).[1],2 It alters fatigue, mood, alertness, motor reaction time, vascular hemodynamics, and pain sensation.[2],[3],[4] Caffeine has also been implicated in carcinogenesis, although the concentrations used to affect cell cycling and apoptosis in the laboratory may not be commonly achieved in vivo.[5]
