What is Caffeine and How Does It Work?
What’s the secret behind that extra kick you feel after your favorite drink? It all comes down to a natural compound called 1,3,7-trimethylxanthine. This is the scientific name for caffeine, and it’s what gives you that boost.
Once consumed, caffeine is quickly absorbed into your bloodstream. About 96% of it is metabolized by an enzyme produced by the CYP1A2 gene. This process varies from person to person, which is why some people feel effects faster than others.
The Science Behind Caffeine
Caffeine works by blocking adenosine receptors in your central nervous system. Adenosine is a chemical that makes you feel tired. By blocking it, caffeine keeps you alert and focused.
The speed of its effects depends on how you take it. For example, coffee hits your system in about 30 minutes, while capsules can take up to an hour. This difference is crucial for timing your intake.
How Caffeine Affects the Body
Immediate effects include increased alertness and energy. Over time, it can also improve your caffeine exercise performance by delaying fatigue and enhancing focus.
However, the way your body processes caffeine depends on factors like genetics and habits. Understanding this can help you use it more effectively to meet your goals.
