Caffeine Science

Caffeine has long secured its place as the most widely used drug around the world — whether found in a cup of coffee or green tea, energy drinks or soft drinks or even in workout supplements and caffeine pills.

The stimulant effects of caffeine are primarily attributed to its interaction with adenosine receptors in the brain. By blocking adenosine, a neurotransmitter that promotes sleep and relaxation, caffeine in turn enhances wakefulness. The interference with adenosine also leads to an increase in dopamine, another neurotransmitter associated with alertness and mood elevation; the result is the unmistakable feeling of alertness and increased cognitive performance that caffeine drinkers experience. Apart from boosting your mental faculties, caffeine intake also enhances physical performance, making it a popular component in workout supplements.

While moderate caffeine intake can offer some health benefits, understanding the how and when of caffeine consumption is crucial to prevent unwanted side effects. In the content below we cover what is a healthy amount of caffeine, why it’s important to track the caffeine content in your favorite beverages, and how to prevent caffeine tolerance.
