Caffeine is a methylxanthine compound that blocks adenosine receptors and increases dopamine and norepinephrine release, which enhances alertness, focus, and physical performance while reducing perceived exertion.
How to Take Caffeine
Caffeine is typically dosed at 100-400 mg daily, often divided into 1-2 doses in the morning and early afternoon, taken at least 6 hours before bedtime to prevent sleep disruption, and tolerance develops with regular use.
