Matcha contains approximately 70 mg of caffeine per teaspoon (about 2 grams), while an 8-ounce cup of brewed coffee typically contains 95-200 mg of caffeine. However, matcha's caffeine is released more slowly into your bloodstream due to the presence of L-theanine, an amino acid that promotes calm focus.
This means that while matcha has less total caffeine than most coffee, it provides a sustained energy boost lasting 4-6 hours without the jitters or crash often associated with coffee. Many people find matcha's balanced energy effect more desirable for productivity and concentration throughout the day.
