Oo, safe naman ang green tea during pregnancy, pero importante lang na moderate lang ang intake mo, most doctors say up to 1-2 cups a day is okay kasi may caffeine pa rin siya, and we want to keep that low during pregnancy. A few of us pregnant moms I know nag-switch to decaf green tea or herbal teas like ginger para sure, pero if you love your green tea, no need to quit completely, just keep it minimal and balanced with lots of water. Better to check with your OB din para sa peace of mind, lalo na at super early pa ng pregnancy mo!
