Can you drink green tea while pregnant?
In moderationYes, green tea is fine in moderation during pregnancy: it counts toward your 200 mg daily caffeine limit, which leaves room for about 2 to 3 cups a day.
Why
Green tea's caffeine counts toward the 200 mg daily ceiling that both the NHS and ACOG set for pregnancy; the NHS counts a cup of tea at around 75 mg, and green tea often runs a little lighter. Two or three cups fit comfortably if you are not stacking coffee on top. One green-tea-specific note: some research suggests very large amounts may interfere with how your body uses folate, the vitamin that matters most in early pregnancy, one more reason moderation is the right gear rather than unlimited refills.
By trimester
In the first trimester, when folate does its most important work, it is worth being a little stricter about not overdoing green tea, and taking your prenatal vitamin at a different time of day than your cup.

Frequently asked questions
How many cups of green tea can I have a day?
Two to three cups keeps you well inside the 200 mg caffeine limit if green tea is your only caffeine source. Add a coffee and the math changes fast, so count everything together.
Does green tea really affect folic acid?
Studies suggest heavy green tea intake may reduce folate absorption; at a few cups a day the effect is not a reason to worry, especially if you take your prenatal consistently. Keeping tea and your vitamin a couple of hours apart is an easy precaution.
Is jasmine or flavored green tea any different?
No, jasmine tea is green tea scented with blossoms, same caffeine, same rules. Herbal blends are a different category: the NHS suggests no more than 4 cups of herbal tea a day and avoiding licorice root.
