Probiotics are effective in enhancing the diversity and health of the microbiome in pregnant women. Giving probiotics prenatally is an important way for mothers to safeguard their health during their pregnancy as well as the health of their babies. With constipation and diarrhea being the two frequently experienced common discomforts during pregnancy, the use of probiotics during pregnancy can help alleviate these problems. Due to the low risk of probiotic-induced bacteremia and fungemia, probiotics are unlikely to reach the fetus' systemic circulation and cause harm.
