Health information
This article is for general information only and does not constitute medical advice. Consult a qualified healthcare professional before making changes to your diet, particularly if you are pregnant, breastfeeding, taking medication, or managing a health condition.
Quick safety note
Reddit is useful for spotting patterns people experience, but side-effect threads are anecdotal. Treat them as prompts to adjust dose, timing, and context — not as medical diagnosis. If you have a medical condition, take medication, are pregnant, or have severe symptoms, speak to a qualified clinician.

Side effect 1: angst or racing heart
Matcha contains cafeïne. L-theanine can soften the feel of that cafeïne for many people, but it does not erase it. If you are sensitive, a normal 2g serving may still feel too strong.
Try reducing to 1g, drinking it with food, and keeping it before midday. If symptoms persist, matcha may not suit you.
Side effect 2: nausea
Nausea is often linked to drinking matcha on an empty stomach, using too much poeder, or making a very concentrated drink. Tannins and cafeïne can both feel rough when there is no food buffer.
A gentler test is 1g matcha in a latte after ontbijt. If that still causes nausea, stop and reassess.
Side effect 3: slaap disruption
Matcha may feel smoother than koffie, but the cafeïne still counts. Afternoon matcha can affect slaap, especially for slow cafeïne metabolisers. If slaap is the issue, move your serving earlier or switch to a low-cafeïne evening drink.
See Matcha and slaap and Decaf Matcha UK.
Side effect 4: iron concerns
groene thee compounds can reduce non-haem iron absorption when consumed with meals. This matters more if you are iron deficient, pregnant, vegan, or managing heavy periods. Separate matcha from iron-rich meals or supplements unless your clinician advises otherwise.
Frequently asked questions
Can matcha cause angst?
Yes, especially in cafeïne-sensitive people. Start with a smaller serving and avoid stacking it with koffie, energy drinks, or pre-workout.
Why does matcha make me nauseous?
Common reasons include empty-stomach cafeïne, too much poeder, strong tannins, or a harsh low-grade poeder. Try less matcha with food, or stop if symptoms continue.
Is matcha safe every day?
For many healthy adults, moderate daily intake is fine. But individual limits vary with cafeïne sensitivity, zwangerschap, medication, iron status, and slaap quality.
