Caffeine: The cheerful companion in your everyday life – everything you need to know!
What is caffeine?
Caffeine is a psychoactive alkaloid that accompanies millions of people around the world every day. It blocks the adenosine receptors in the brain, thus ensuring alertness and energy. With the chemical formula C8H10N4O2, it quickly penetrates the blood-brain barrier and exerts its effects. Did you know that caffeine belongs to the purine family, which is also found in our DNA?
