Yes, matcha contains about 40-60 mg of caffeine per serving, but unlike coffee, matcha also contains the amino acid L-theanine. It slows down the release of caffeine – softening its effects and promoting relaxation.
Instead of the quick caffeine spike followed by an energy crash, like with coffee, the energy from matcha is released more slowly and steadily. This is why matcha provides a sense of calm alertness. Additionally, caffeine and L-theanine working together can help improve focus for tasks that require cognitive effort.
