What Is Caffeine?

Did you know caffeine is actually one of the world’s most commonly used drugs? Caffeine is considered a mild stimulant and is a chemical found in food.  Coffee, tea and chocolate are the most common foods that contain caffeine.  Most people think they need caffeine to stay awake or alert.  It is true that caffeine gives you an energy boost and it steps up your heart rate.  However, that feeling is short-term and will fade.

Everybody’s body reacts differently to caffeine.  Some may not notice any changes after drinking a caffeinated beverage and others may notice changes.  Your Health Care Provider may want you to drink or eat less caffeine, especially if you are Pregnant, have Coronary Heart Disease or a Peptic Ulcer.

Should I Limit My Caffeine Intake
There has been no evidence that caffeine in small to moderate amounts causes negative health problems.  The recommended amount of caffeine per day is 200-300 milligrams (mg) a day.  That is about the amount found in 2 cups of brewed coffee per day.  Caffeine does not build-up or get stored in your body.  If you drink or eat too much caffeine your body expels it through urine, breast milk, saliva, or semen.  However too much caffeine can cause problems and make you feel funny.
