Is 1 tablet of theanine serene w/relora and 500 mg maca root ok to continue taking daily after i am pregnant and/or breastfeeding?

NO: Take no medications, including herbal medications, without discussing them with your doctor during pregnancy. Any substance that has an effect on the body is called a drug, whether or not you need a prescription to get it. There are no drugs which baby needs, except perhaps for extra vitamins and iron. An occasional Tylenol (acetaminophen) for pain is generally ok, but don't take anything else. Eat healthy.
