What is caffeine?

Caffeine is a chemical classified as an alkaloid, belonging to the methylxanthine family. It is found naturally in a variety of plants, including coffee beans, tea leaves, cocoa beans, and some nuts. Caffeine is known for its stimulating effects on the central nervous system, which can result in increased alertness, concentration, energy, and reduced fatigue.

When consumed, caffeine is rapidly absorbed by the body and can have a number of effects, including increased heart rate, dilation of blood vessels, and increased production of stomach acid. Its effects can vary from person to person, depending on individual sensitivity to the substance.

Although caffeine is most commonly associated with coffee and tea, it is also added to many soft drinks, energy drinks, over-the-counter medications, and dietary supplements.
