Matcha For Mental Energy
Green tea does more than just keep you awake, it can also increase your mental energy!
The key active ingredient is caffeine, although matcha doesn’t contain as much caffeine as coffee, but just enough to produce a response without causing the “jittery” effects associated with too much caffeine.
Caffeine blocks an inhibitory neurotransmitter in the brain called Adenosine. This way, it actually increases the firing of neurons and the concentration of neurotransmitters like dopamine and norepinephrine (1, 2).
Caffeine has been intensively studied before and consistently leads to improvements in various aspects of brain function, including improved mood, vigilance, reaction time and memory (3).
However… green tea contains more than just caffeine. It also has the amino acid L-theanine, which is able to cross the blood-brain barrier (4).
Studies show that caffeine and L-theanine can have synergistic effects. The combination of the two is particularly potent at improving brain function (8).
Because of the L-theanine and the smaller dose of caffeine, green tea can give you a much milder and different kind of “buzz” than coffee.
Many people report having more stable energy and being much more productive when they drink green tea, compared to coffee.
