Can I Drink Green Tea While Pregnant? Caffeine Limits 2026
Short answer: In moderation. Green tea is fine if your total daily caffeine stays under 200mg, about 2–3 cups.
Mind Your Total Caffeine
Green tea contains caffeine (about 25–45mg per cup). Keep your total caffeine from all sources under 200mg per day. Green tea also slightly reduces folate absorption, so don't rely on it around the time you take your prenatal.

Is Green Tea Safe During Pregnancy?
Green tea is safe in moderate amounts. The main consideration is caffeine: health authorities advise keeping total daily caffeine below 200mg during pregnancy. A cup of green tea has roughly 25–45mg, so 2–3 cups can fit within your limit, but remember coffee, black tea, cola and chocolate all count too.
Green Tea and Folate
Green tea contains compounds (catechins) that can slightly reduce the absorption of folate, a key nutrient for your baby's neural development. This isn't a reason to avoid green tea, but it's sensible not to drink large amounts, and to space it away from your prenatal vitamin and folate-rich meals.
Practical Tips
Brew it weaker, choose decaf green tea if you want more cups, and track caffeine across the whole day. If you're having a coffee as well, factor that in, it's the daily total that matters.
Enjoying Green Tea Safely
- 2–3 cups a day, within the 200mg caffeine limit
- Decaf green tea, for extra cups without caffeine
- Weaker brews, shorter steeping time
- Away from your prenatal, to protect folate absorption
What to Watch
- Large daily amounts, caffeine adds up fast
- Green tea extract supplements, highly concentrated, avoid
- Combining with lots of coffee, exceeds 200mg easily
