Matcha

The powder has repeated human wins on cholesterol and blood pressure, and every liver injury traces back to concentrated catechin capsules.

Three squares: proven in human trials. Two: a strong signal. One: early human data. Striped: the trials disagree.

How you'll know it's working

When to judge
Focus: the same day

Why it works

Matcha gives you the whole ground leaf rather than a brew, so its catechins arrive with a distinctive amount of L-theanine. That is the amino acid that blunts caffeine's edge. The pairing is how it works: caffeine for alertness, theanine for the calm that sets matcha's effect apart from coffee's.

Where it fits

Matcha is a move in one protocol. Each one opens the plan it sits in.
