Yes it does but each ½ teaspoon serving (1gram) contains 34mg of caffeine, compared to 70-180mg for a cup of coffee.
It is easily tolerated by most people for whom coffee makes them jittery; this is because all of the other components that make up Matcha slow down the release of caffeine into the body. It usually takes three to six hours for this minimal amount of caffeine to be absorbed into the bloodstream; however, the mental alertness and energy are apparent almost immediately upon drinking it.
The ‘type’ of caffeine in Matcha is different to that of caffeine in coffee, called Theophylline, which gives you a much more sustainable release of energy throughout the day.
In contrast to coffee, this timed-release mechanism tends to inhibit any sudden insulin increases, so there is no “crash” associated with quick drops in blood sugar that so many coffee drinkers feel an hour or so after drinking a cup. Nor does Matcha stimulate the production of cortisol, the stress hormone, as coffee can.
In other words, Matcha doesn’t give you that “weird” feeling. If you’re wary of caffeine, you can relax! And let Matcha help you relax!
So in a nutshell the combination of caffeine, phytonutrients, antioxidants and amino acids produces a fabulous effect on Matcha drinkers – the envious ability to be able to focus and be productive over an extended period of a few hours (for some, up to six hours).
