Caffeine is a naturally occurring substance in coffee. As you probably know, it can really boost energy and mental performance!
It is a legal and acceptable natural performance enhancing drug. Not all of the benefits of drinking coffee come from caffeine though. Coffee naturally contains polyphenols, antioxidants and other healthy compounds that can boost your brain power. Safe and natural effective brain-boosting compounds are called 'nootropics'. Coffee is a great nootropic!
