Each mint contains 40 mg of caffeine (for reference: a cup of coffee has about 90 mg) so you can take them as you need, without having to worry about the jitters. If you feel like you need a bit more energy, just pop another in!
Promising review: "I was a bit skeptical at first, knowing that most caffeine boost/coffee replacement products tend to be ineffective. 40mg of caffeine per mint sounded unbelievable. To my surprise, these mints did EXACTLY what they were supposed to. I use to work at Starbucks and am a huge coffee drinker, so I never really feel the caffeine energy boost anymore. However, with only ONE mint I immediately felt like I had energy again. Not only that, but they did not give me a headache or any kind of stomach cramp as some sugar-free/caffeine products can give. The spearmint flavor is VERY strong. It's like a super Altoid, but it's manageable for sure. I have yet to try the winter, but am confident it's just as good! These mints will get the job done. Much better then a 5-Hour Energy, etc." —Mariah
