Caffeine: A Small Molecule With a Big Effect

One of the key reasons coffee holds such a place in our daily lives, caffeine is a stimulant compound found naturally in coffee beans as well as in tea, cocoa and certain other plants.

By temporarily suppressing the effect of adenosine in the brain, caffeine can contribute to increased alertness and focus — though its effect varies according to the amount consumed and individual sensitivity.

In short, behind every cup of coffee there is a small but powerful molecule accompanying our daily ritual.
