How much caffeine is in Matcha?

Because you whisk and drink the whole leaf, matcha runs higher than steeped green tea, around 70 mg per cup. Its L-theanine smooths the edge, giving a steady, focused energy without the coffee jitters.

8 oz70 mg0 g

~1 tsp powder; whole leaf consumed so higher than steeped green tea. Range ~38–88 mg. Contains L-theanine.

Will Matcha affect your sleep?

At 70 mg, matcha needs an hour or two to fall under 50 mg and clears over a handful of hours. An afternoon bowl is generally fine by bedtime, though a late one can keep alert minds humming.
