"Matcha gave me the jitters" is common and usually explainable. It sits alongside dirty matcha.

Note: matcha is whole powdered green tea, so it is meaningfully caffeinated. General information only; if you are caffeine sensitive, pregnant or medicated, moderate intake and check with a pharmacist.

The answer is undramatic: matcha is whole powdered green tea and is meaningfully caffeinated, so jitters usually come from too much, too strong, or drinking it on an empty stomach. The most common hidden cause is the dirty-matcha trap: a dirty matcha adds an espresso shot, stacking two caffeine sources, so a "calming green tea" quietly becomes a double hit, often without the drinker counting both. If your jitters started when you switched to or added dirty matcha, that, not "matcha", is almost certainly the cause. See caffeine in tea. The L-theanine point

Matcha carries more L-theanine than most teas, and for many drinkers the caffeine-plus-theanine combination genuinely smooths into a calmer, more focused alertness than the same caffeine from coffee. But "many" is not "everyone": sensitivity varies, the ratio shifts with grade and dose, and a large or stacked dose simply overrides the theanine. The reputation is real but conditional on dose, not an absolute property of the powder, so if you are getting jitters, do not assume the theanine "should" cancel them and push on, treat it as a dose signal and scale back.

If matcha is reliably wiring you, work through this in order rather than quitting; most people stop well before the last step. First, halve the powder, since strength is the commonest single cause and a 1g bowl is plenty for many. Second, move it to with-or-after food and earlier in the day. Third, unstack: if you are adding espresso or also drinking coffee, that is almost certainly the real problem. Fourth, hydrate alongside. Fifth, if you are caffeine-sensitive, pregnant or medicated, accept that a lower ceiling is simply yours and check with a pharmacist. Treat matcha with the same dose respect you would give strong coffee and the calm-focus reputation tends to show up. See matcha water ratio. What to buy
