Common Caffeine Sources in Your Pantry
Most people know that coffee and tea are primary sources of caffeine, but many other household staples contain it as well. Cacao beans, kola nuts, and guarana berries are all naturally caffeinated plants used in various products found in most kitchens.
Coffee and Tea Products
While brewed coffee is a high-caffeine beverage, even decaffeinated versions contain trace amounts of the stimulant. An 8-ounce cup of decaf coffee might have anywhere from 2 to 15 milligrams of caffeine, as the process for removing it is not 100% effective. For tea, black and green varieties contain significant caffeine, while herbal teas like peppermint or chamomile are typically caffeine-free.
Chocolate and Cocoa
Chocolate is a delicious and often-overlooked source of caffeine, with the amount varying significantly based on the cacao content. The darker the chocolate, the higher the caffeine content, as caffeine is naturally present in the cocoa solids. White chocolate, made from cocoa butter, typically contains no caffeine. Foods and beverages made with chocolate, like hot cocoa mix, chocolate milk, and chocolate-flavored desserts, also contribute to caffeine intake.
Sodas and Energy Drinks
Many sodas contain added caffeine, which can surprise consumers who don't drink coffee or tea. While cola drinks are the most well-known, some non-cola sodas like Mountain Dew also have significant caffeine content. Energy drinks, designed to provide a stimulant boost, contain highly concentrated caffeine, sometimes more than 160 mg in a 16-ounce can.
Unexpected Household Items with Caffeine
Beyond the expected food and drinks, caffeine can be found in several surprising household items. Reading labels is key to monitoring your total consumption.
Medications and Pain Relievers
Certain over-the-counter pain relievers and headache medications contain caffeine, which is added to enhance the pain-relieving effects. Brands like Excedrin and some cold and flu tablets list caffeine as an active ingredient. Some non-prescription weight-loss and alertness aids also contain high doses of caffeine.
Health Foods and Supplements
Even products marketed as healthy can contain caffeine. Matcha, a finely ground green tea powder, can have a high caffeine concentration because it uses the entire tea leaf. Kombucha, a fermented tea, also contains some caffeine from its tea base. Some protein and energy bars incorporate caffeine from sources like green tea extract, coffee beans, or guarana.

Conclusion
