Evidence Summary

Tea powder is a finely ground form of dried tea leaves — most commonly green tea (matcha) or black tea — that delivers concentrated plant compounds including catechins, caffeine, and theanine. Clinical trials show it can modestly reduce post-meal blood sugar spikes, with one study in type 2 diabetes patients finding a 65% reduction in risk of large glucose fluctuations when black tea powder with fiber was consumed before a meal. Matcha specifically has shown early promise for improving emotional perception and sleep quality in older adults with mild cognitive decline over 12 months, and may support muscle adaptation and reduce exercise fatigue when taken at 1.5 g twice daily during resistance training.
