Sources of Caffeine

Although coffee is always talked about, caffeine is found in many other sources, including:

Tea: While most herbal teas (such as chamomile) do not contain caffeine, others contain varying amounts. For example, green includes 25 to 29 mg per cup, while black packs more, 25 to 48 mg per cup.
Chocolate Cocoa: Naturally contains caffeine. One ounce of dark chocolate offers 12 mg.
Chocolate Ice Cream: This treat also has trace amounts of caffeine, about 4 mg per 1-cup serving.
Energy Drinks: An 8.4-oz can of Red Bull contains 80 mg, while a 16-oz can of Monster contains 160 mg.
Caffeinated Water: In this case, caffeine is added to the mix. One variety, Hint's Apple Pear Flavor, contains 60 mg of caffeine per 16 oz. Bottle.

On average, most adults can safely consume about 200 to 400 mg of caffeine per day. This amount is roughly equivalent to:

2 to 4 cups of brewed coffee
5 to 10 cans of cola
2 to 4 energy drinks
