Tag: Caffeine mechanism

Studies have revealed that caffeine's interaction with the brain is more complex than simply promoting alertness, with its effects on the excitatory neurotransmitter glutamate being particularly nuanced. Far from directly inhibiting glutamate at normal intake levels, caffeine primarily works by blocking adenosine, which ultimately leads to an *increase* in glutamate release.

According to research, it takes between 15 and 30 minutes for caffeine to reach its peak level in the bloodstream, kicking off the chain reaction that causes a caffeine buzz. This effect is not due to providing your body with energy but rather by manipulating key chemicals in your nervous system to promote wakefulness.
