Caffeine and Your Health

What is Caffeine?

Caffeine is a chemical found naturally in coffee beans, tea leaves, cocoa beans (used to make chocolate) and kola nuts (used to flavor cola soft drinks). It is also commonly added to other products like energy drinks, soda, and medication. Caffeine makes you feel more awake and alert because it is a drug that stimulates the nervous system. It is recommended that adults consume no more than 400 mg of caffeine daily, and teens no more than 100 mg daily.
