It seems like coffee keeps the world running, and experts say that caffeine in moderation can be beneficial. But it’s easy to overdo it, especially when we don’t realize something contains caffeine. Here are a few surprising sources of caffeine:   

  • Let’s start with: Chocolate. Caffeine is found naturally in cocoa beans, and the darker the chocolate, the heavier the dose. In fact, a small bar of dark chocolate can have as much caffeine as a can of cola.

  • Another surprising source of caffeine: Weight-loss supplements. Even though research shows that caffeine has no significant effect on weight loss, diet pill manufacturers still pack it into their products. In fact, a study by ConsumerLab.com found that some weight-loss supplements have as much caffeine as 12 cups of coffee!

  • Speaking of pills: Some pain relievers will give you the same jolt as a double espresso. That’s because caffeine helps speed the absorption of pain meds. So, make sure you read the label of any meds you take, and stick to the recommended dosages. 

  • The last product that contains caffeine will surprise most people: Decaf coffee. Researchers at Consumer Reports tested 36 different brands of decaf, and most of them still contained about 20 milligrams of caffeine per cup. That’s one-fifth of the caffeine in a cup of regular coffee, but still enough to keep you awake at night.
