You can do a quick Google search for all of the benefits, but from my point of view and experience it was essential during pregnancy and postpartum. During pregnancy, probiotics clear up all of the bad bacteria in your system. It will prevent UTIs and kidney infections. Postpartum, it is important to take a probiotic when breastfeeding to prevent issues like thrush. A lot of women are given antibiotics intravenously during childbirth, and a probiotic is necessary afterward to prevent thrush. Doctors won't tell you though, or at least mine didn't. My doula was the one that told me, and thank God that she did!
