Is Green Tea Safe During Pregnancy?

What is the safest way to think about this?

ACOG says moderate caffeine consumption below 200 mg per day does not appear to be a major contributor to miscarriage or preterm birth, while the relationship with fetal growth restriction remains unclear. MotherToBaby notes that heavy green-tea intake may affect folate status because catechins can interfere with folic acid absorption. The practical check is amount, timing and whether the product is brewed tea or a concentrated supplement.

What is generally okay?

• Count green tea toward the total daily caffeine limit from coffee, tea, matcha, cola, energy drinks, chocolate and medicines.
• Take prenatal folic acid as directed and ask whether tea timing matters if you drink several cups a day.
• Choose plain brewed green tea instead of detox, weight-loss, energy or herbal-blend products.

What should you avoid or double-check?

• Avoid green tea extract, fat-burner capsules, detox teas or concentrated catechin products unless your clinician specifically reviews them.
• Avoid using green tea to replace meals, fluids, iron treatment or nausea care.
• Avoid stacking green tea with matcha, coffee, energy drinks or caffeine pills without counting the total.
