Caffeine – RGH E-Bulletin


Caffeine is a methylxanthine compound used medicinally to stimulate the central nervous system in combating fatigue and drowsiness. Caffeine also stimulates skeletal muscle contraction and gastric secretion. Caffeine has a medical indication for the management of neonatal apnoea, and may also have a role in sports medicine with ongoing research on its use to enhance endurance in elite athletes.

Caffeine occurs naturally in the leaves, nuts and seeds of plants. Guarana derivatives, available in many forms in Australia, are produced from the guarana plant seeds (which contain 3.6-5.8% caffeine). In Australia, if caffeine (or guarana) is added to a product then the food must be labelled to indicate that it contains caffeine.
