The things your body needs to stay alive basically. Things like your sugars and proteins and fats, they all give you energy. Therefore if you arent taking in enough of these nurtrients, you wont have much energy. There is no chemical that MAKES you tired, its the lack of other chemicals, or lower levels. The most common is taurine, it is an amino acid in our body. If you are to read the back of an energy drink, taurine is responsible for keeping us awake and functioning, so therefore, low levels in taurine will make you tired.
