Caffeine, perhaps the best known legal stimulant in the world, is found in coffee, tea, chocolate and many soft drinks. Technically a methylxanthine, caffeine exerts its effects by interacting with the sympathetic nervous system, the branch of the nervous system that controls both arousal and metabolic rate through the release of epinephrine (adrenaline) and norepinephrine (noradrenaline). Caffeine blocks the action of a chemical called adenosine (which inhibits the actions of epinephrine) and also inhibits an enzyme called phosphodiesterase, which normally counteracts adrenaline and noradrenaline by breaking down another chemical called cAMP.
By stimulating the central nervous system and causing arousal, caffeine can be noticeably ergogenic during high intensity exercise, such as weight training, especially when used only occasionally to enhance performance(1-3). Caffeine also has a powerful lipolytic effect(4), increasing the mobilization and therefore oxidation (burning) of body fat stores. This effect on fat use may also contribute to the performance enhancing effects caffeine exerts during long distance and endurance exercise events(5).
Caffeine can be used to aid in fat loss (e.g., 200-600mg / day) in conjunction an appropriate diet and exercise program and with other agents that promote fat use and / or thermogenesis, such as Green Tea Extract. For use as an ergogenic aid, caffeine is most effective if taken only infrequently (200+mg / dose) to prevent adaptation to its effects. Bodybuilders who want to “dry out” for a competition may use caffeine in conjunction with other products like Vitamin C to promote a diuretic effect. Products like Alpha Lipoic Acid, Creatine Ethyl Ester, and Waxy Maize could also be used in a pre-contest program to maximize muscle glycogen storage (“carb up”), and increase muscle size and muscularity.
True Nutrition's caffeine powder provides greater control over caffeine intake than beverages and soft drinks, which vary in caffeine content (and the content of other xanthines and related stimulants). Note, of course, that consuming caffeine late in the day may cause sleep difficulties. CAUTION: Overuse of stimulants can lead to health problems. Please consult your physician before taking caffeine supplements.
