The Problem With Regular Matcha
Love matcha, but not the jitters?
Traditional matcha is packed with caffeine. For many, that means anxiety, disrupted sleep, and a dependence cycle — not the calm ritual you wanted.
Caffeine Crash
Energy spikes followed by afternoon crashes leave you more tired than before.
Anxiety & Jitters
Sensitive to caffeine? Regular matcha can trigger anxiety and heart palpitations.
Sleep Disruption
Evening cravings denied. Caffeine in matcha can ruin the sleep you need most.

All the ritual. Zero caffeine.
