Caffeine is the bitter substance that occurs naturally in more than 60 plants. These plants include; coffee beans, tea leaves, kola nuts and cacao pods. Another type of caffeine is called synthetic caffeine (man-made), which is typically added to medications, foods and drinks. For example, pain relievers, cold medicines, and energy drinks like Redbull.
Caffeine can affect your body in a variety of ways. Here are a few:
Can affect your body’s metabolism, by stimulating your central nervous system (makes you feel more awake and boosts your energy)
It is a diuretic, which means that it helps the body get rid of extra salt and water by urinating more
Increases the release of acid in the stomach, causing the potential for heartburn and/or an upset stomach
Increase in blood pressure
Now what happens when you have too much caffeine?

Caffeine is not for everyone. There are some people who should avoid caffeine as much as possible. They include: those who are pregnant, who have a sleeping disorder, migraines, anxiety, ulcers, high blood pressure, and arrhythmia (problems with the rate of your heart).
Those who go through a caffeine withdrawal are those who consume it on a regular basis and then suddenly stop. When this happens there are some symptoms that will appear for a few days and then go away.
