How a lot caffeine does matcha include?
“Usually talking, a gram of matcha powder—which usually equates to round a half teaspoon—comprises round 30 milligrams of caffeine,” says Pasquariello, though some manufacturers might have as a lot as 40 to 45 milligrams of caffeine per gram. “Most manufacturers in the marketplace advocate utilizing about 1 teaspoon of matcha powder per cup of liquid, in the end equating to round 60 to 70 milligrams or so of caffeine, usually a bit extra relying on the model.” (For reference, the FDA says that adults can safely devour as much as 400 milligrams of caffeine per day.)
Nonetheless, Pasquariello says there are a number of elements that may affect how caffeinated your cup of matcha shall be, such because the brewing methodology, the kind of powder you employ, and the serving dimension. Some manufacturers, she provides, course of their powder to yield an excellent larger caffeine content material. Matcha’s caffeine content material can be influenced by the point of harvest, climate circumstances all through development, and the age of the leaves (with caffeine content material petering out because the leaves become older), per a 2021 assessment revealed within the journal Molecules.

This might sound complicated, since inexperienced tea and matcha are produced from the identical factor: inexperienced tea leaves. However the discrepancy between the 2 drinks “has to do principally with how the tea is brewed,” Pasquariello explains. “Within the case of matcha, you are whisking the powder—which is fabricated from very finely floor tea leaves—into water and consuming it in a extra concentrated format.” In the meantime, inexperienced tea merely infuses water with the tea leaves, then strains and discards them.
In different phrases, matcha presents the total leaf (learn: peak caffeine *and* antioxidant potential) in powdered type.

“Decaf espresso, relying on selection, comprises about zero to 6 milligrams of caffeine per cup,” Pasquariello provides, “so matcha’s caffeine content material falls someplace in between the 2.”
Is matcha higher than espresso for nervousness?
Pasquariello says that matcha could also be a very good center floor for individuals who want one thing stronger than decaf or inexperienced tea, however can’t fairly abdomen extra sturdy caffeinated bevs like espresso. “Many individuals expertise that matcha delivers extra of a ‘sluggish burn’ type of caffeine launch, retaining their power ranges extra steady than they may sometimes really feel with caffeine,” she explains. “This may be useful for individuals who expertise caffeine jitters or elevated nervousness when consuming espresso.”
That is largely attributable to the truth that teas (together with matcha) have L-theanine, an amino acid with antioxidant properties that may promote calm within the physique. “L-theanine acts as a buffer throughout the digestion course of, which helps stop jitters and the crash that’s usually related to espresso,” Christina Manian, RDN, beforehand informed Effectively+Good. And curiously, a small 2018 research revealed within the journal Vitamins discovered that individuals who drank matcha had decrease stress and nervousness ranges than individuals who drank a placebo.
