Caffeine – All about it

What makes an individual’s caffeine experience so impacting is the fact that the human body actively responds to its chemical structure (1,3,7-trimethylxanthine). In addition to that, the ingredient is classified as a potent psychoactive drug. We have been discussing about caffeine for so long, thought where exactly it originated from? The term “caffeine” has been derived from the German word kaffee and also from the French word for it, café, each of them meaning one thing – coffee.
