The caffeine market is exploding these days. It seems there are new caffeine-infused products hitting the shelves every day. From energy drinks to gum and even jerky, the world’s love affair with caffeine shows no signs of slowing down. In the American Chemical Society’s latest Reactions video, they take a look at the science behind the world’s most popular drug, including why it keeps you awake and just how much caffeine is too much. For coffee and caffeine lovers around the world, this video won’t scare you away from it, like some informative videos do. Rather, this video is just looking to educate you on the science behind caffeine and how your body reacts to it. It’s time you really understand.

The video explores what happens to caffeine once it enters the body and is broken down into theobromine, paraxanthine, and theophylline molecules. So to break this down in a non complicated way, when caffeine is taken in by the body, it breaks down into the three molecules I listed above. In the brain, these 3 molecules attack the adeonsine receptor, which is what makes you tired and prepares your body for sleep. The reason for this is because adenosine and caffeine have a very similar molecular make-up and it’s easy for caffeine to bind to adenosine. The caffeine increases the activity in the brain, and thus helps keep your brain and body moving. Short and sweet and hopefully that made a little bit of sense…

While this video isn’t meant to scare you away from drinking caffeine, it does say that anything more than 400oz , or about 3 cups of coffee a day is a bit overkill on your body. It also states that caffeine becomes toxic after consuming 10 grams of it. This is the equivalent of about 75 cups of coffee. That’s rather extreme and I hope none of you ever get to that level even during your worst all-nighter, but it’s interesting to know. Find out more by watching the video below.
