Health & Caffeine
Benefits, caffeine, and safety.
-
Can I drink matcha every day?
Yes, most people can drink matcha daily. 1-2 servings per day is typical. Watch your total caffeine intake, and be aware that matcha contains some lead from the leaves — moderate consumption is key.
-
How much caffeine is in matcha?
A typical serving of matcha has about 70mg of caffeine — roughly the same as a cup of coffee. But the L-theanine in matcha provides a calmer, more sustained energy without the jitters.
-
Is there lead in matcha? What about heavy metals?
Lead and heavy metals in matcha are a legitimate concern, but the risk depends on where your matcha comes from. Japanese-grown matcha from reputable producers typically tests well below safety limits. Chinese matcha has higher contamination rates. Since you consume the whole leaf, sourcing matters more than with regular tea.

Matcha vs coffee: What's actually different?
Matcha has less caffeine than coffee (40-70mg vs 95-200mg per serving) but contains L-theanine, which creates a calmer, more sustained alertness. The 'slow release' caffeine claim lacks evidence — the smoother experience comes from L-theanine moderating caffeine's effects, not slower absorption.
-
Why does matcha give you calm energy?
The combination of caffeine and L-theanine in matcha creates 'calm alertness' — L-theanine promotes relaxation and alpha brain waves while caffeine provides focus. This synergy is supported by research, though most studies use higher doses than a single matcha serving provides.
-
Why does matcha make me nauseous?
Matcha nausea usually comes from drinking on an empty stomach, using too much powder, or caffeine sensitivity. The tannins and catechins in matcha can irritate an empty stomach. Fix it by eating something first, reducing your serving size, or switching to higher-quality matcha.
