Matcha
Also known as: powdered green tea
Matcha is finely ground green tea from shade-grown leaves that is consumed whole rather than steeped. It contains caffeine, L-theanine and catechins (mainly EGCG), so it is stimulating but usually calmer than coffee.
What it is used for
- alertness and focus (caffeine + L-theanine) – moderate evidence
- antioxidant catechins – moderate evidence for green tea in general
- mild metabolic support – weak evidence, small effect
Forms and how they differ
ceremonial grade
milder taste, meant for drinking with water
culinary grade
stronger taste, for lattes and baking
capsules
no taste, but a smaller dose than a cup
Pairs well with
Water at about 70–80 °C, or milk or a plant drink.
Do not combine / separate
Count total caffeine from coffee, energy drinks and pre-workouts. Do not drink it right with iron-rich meals or an iron supplement.
Watch out for
Limit total caffeine during pregnancy and breastfeeding. If you have high blood pressure, anxiety, heart-rhythm problems or liver disease, or take medicines (e.g. thyroid hormones, anticoagulants), consult your doctor.
Safety
EFSA considers up to 400 mg caffeine per day safe for healthy adults (200 mg in pregnancy); concentrated EGCG extracts at high doses may strain the liver. Do not exceed the label dose.
Practical tip
If coffee makes you jittery, try matcha in the morning – L-theanine smooths the caffeine onset.
