Are probiotic supplements safe for pregnant/nursing women?
There is strong evidence that probiotic supplementation during pregnancy improve newborn's immunity and decrease allergies. For nursing infants, immunity/allergy improvements have also been observed.In thousands of hours of research, I have not come across evidence of probiotics being unsafe for pregnant/nursing women. But, as always, please consult a physician before taking supplements when pregnant/nursing. But, you should still check with your doctor to be 100% that any supplement, including probiotics, is safe for you during pregnancy.
Lastly, people with liver/kidney issues should proceed cautiously with probiotic supplementation.
