Description
Caffeine is an alcoid and is found in guarana, kola nuts, coffee, tea and cocoa beans. It is the most popular drug in the world and is a powerful central nervous system stimulant. Once caffeine is consumed, it is absorbed into the bloodstream and other body tissues. It takes about half an hour to reach maximum concentration in the body. Research has shown that caffeine supplements help improve energy levels, mood, various aspects of brain function, and fat burning. Caffeine supplements for bodybuilding have also been shown to benefit endurance and strength athletes as well as athletes trained during HIIT (high-intensity interval training). For bodybuilders and fitness enthusiasts, caffeine supplements are the cornerstone of any successful training and nutrition program.
