Caffeine, known in medical circles as trimethylxanthine, is an alkaloid that also works as a psychoactive drug and a stimulant of the central nervous system. Caffeine is found naturally in a variety of plants. Caffeine can also be created synthetically. The word caffeine is derived from the German word kaffee and the French word café, which both translate to coffee. When taken, caffeine is absorbed within 45 minutes and its effects wear off after three hours.

Enjoy having two to four cups of coffee a day without worrying. However, the Mayo Clinic states that moderate caffeine consumption (about four to seven cups of coffee each day) could present some long- term effects.

Certain types of antibiotics, such as norfloxacin, can lengthen the time caffeine stays in the body. When ephedra, a herbal dietary supplement, is taken with caffeine, it could raise the chances for coronary disorders and seizures and could lead to death.
Cutting Back on Caffeine

There are things that can be done if you want to cut back on your caffeine intake. It's best to cut back gradually as going cold turkey can cause irritability, headaches and in some cases vomiting. Keep track of how much coffee you drink. Try to reduce your daily coffee intake by half a cup. Another method is to switch to decaf, which tastes similar to the caffeinated kind of coffee.
