Each of our pure ceremonial grade matcha green tea cans has 40 mg of caffeine. This is about half the caffeine in a cup of coffee. One of the benefits of matcha is that the energy is smooth and long lasting. You'll get a boost without the jitters, feelings of anxiety, or a crash. It's also the perfect amount of caffeine for an afternoon pick me up when you want something for energy but won't keep you up all night or disrupt sleep. Of course, you wouldn't want it too late in the evening and we recommend following your typical caffeine cut off time. But lower caffeine is a great way to protect and prioritize your sleep.
