Since there may be a lot of caffeine in green tea, breastfeeding women may need to avoid consuming any green tea products. Although normal intakes (such as one cup per day) are probably safe, problems could potentially occur. Caffeine passes through breast milk and may cause problems in breastfed infants. Before consuming green tea, breastfeeding women should ask their healthcare providers about the possible risks.
