Is Matcha Safe During Pregnancy?
This is a question worth taking seriously, and it's also one we're not going to answer for you.
Matcha contains caffeine, and caffeine during pregnancy is something healthcare providers manage on a person-by-person basis. What follows is general background on how caffeine, L-theanine, and EGCG relate to pregnancy, not a personal verdict on whether matcha fits yours.
Health note: This post is general information, not medical advice, and it isn't meant to diagnose, treat, cure, or prevent any condition. Matcha contains caffeine. If you're pregnant, trying to conceive, or breastfeeding, talk to your OB, midwife, or doctor before changing your caffeine intake.
The Caffeine Question
Major health organizations, including ACOG (American College of Obstetricians and Gynecologists) and the NHS, commonly reference keeping total caffeine intake under 200mg per day during pregnancy as general guidance, though the right number for you can vary and some providers recommend less. A one-teaspoon serving of matcha has roughly 30 to 70mg of caffeine, but your total daily intake also depends on any coffee, tea, soda, chocolate, or other caffeine sources you're having that day.
Because health history, trimester, and provider guidance are all individual, this is exactly the kind of number worth reviewing with your own care team rather than calculating from a blog post.
Why Caffeine Gets Extra Attention in Pregnancy
Caffeine crosses the placenta, and a developing fetus processes it differently than an adult does. Researchers have studied whether higher caffeine intake during pregnancy is linked to outcomes like miscarriage or lower birth weight, and the findings have been mixed: some studies report an association at higher intake levels, others don't find one. That mixed picture is part of why guidance tends to focus on staying within a general moderate range rather than a single guaranteed-safe number.
What About L-Theanine?
L-theanine is the amino acid matcha is often associated with alongside caffeine. It has a generally recognized safety profile in general use, but there isn't a large body of research specifically on L-theanine during pregnancy, so we're not going to make a claim either way. If it's something you're curious about, it's a good one to bring up with your provider.
What About EGCG?
Matcha also contains EGCG, a compound some research has looked at in connection with folate absorption, which matters in early pregnancy. This is an area of ongoing research rather than settled science, and folate needs are individual, so it's worth mentioning your matcha habit to your provider, especially in the first trimester.
Morning Sickness
Separate from the safety question, caffeine can make nausea feel worse for some people, and nausea is already common in early pregnancy. If you're dealing with morning sickness, that's worth noticing regardless of what the research says.
The honest bottom line: matcha is a caffeinated tea, and how it fits into a pregnancy is a personal medical question, not a marketing one. Talk to your OB or midwife about your specific caffeine limits, your trimester, and your health history before deciding what role matcha, or any caffeine source, plays in your routine.
If you and your provider land on 'yes, in moderation,' Naka, our barista grade, in a latte is an easy way to keep it to one measured serving. Find it at matchabrand.com.
