Probiotics For Pregnant Women: Best Probiotics During Pregnancy

During pregnancy, changes in hormone levels, differences in water intake and diet, and just the stress of pregnancy on the body often results in digestive issues, namely constipation, bloating and diarrhea.

To prevent these digestive issues, and other microbiome imbalances which can cause problems elsewhere like vaginal thrush, we recommend probiotics. Probiotics are most often taken orally and contain numerous bacterial colonies to rebalance your gut microbiota ー this is especially important during pregnancy.

Probiotics During Pregnancy

As many women experience diarrhea or constipation during pregnancy, and as pregnant women have to eat more food than they’re used to, probiotic consumption is common among pregnant women to develop a healthier digestive system.

Scientists originally believed that probiotics cannot pass on to the unborn child as bacteria cannot pass through the umbilical cord and enter fetal circulation. However, recent evidence does suggest that maternal microbiota can cross through to the fetus via other pathways which has benefits for fetal health.

In the meantime, probiotics during pregnancy are perfect for cultivating gut flora in the mother which will have long-term benefits.

Are Probiotics Safe During Pregnancy?

Is it safe to take probiotics during pregnancy?  Mostly safe. Probiotics may increase the risk of pre-eclampsia during pregnancy. For this reason, you should ask your doctor before taking probiotics while pregnant, particularly if you have risk factors for pre-eclampsia, such as high blood pressure  or obesity. If you do have these issues, you may want to take them once you have delivered your baby instead – the probiotics will then both benefit your own gut and your baby’s as probiotics pass through breastmilk.

Pregnant or not, probiotics can also be dangerous in people who have compromised immune systems. This is because you are ingesting live bacteria which may overwhelm your immune system. If you have compromised immunity such as a low white blood cell count, or suspect that your baby might have an immune disorder, don’t take probiotics without consulting a doctor first.

Benefits Of Probiotics During Pregnancy

Research suggests that probiotics taken during pregnancy or nursing have several benefits for babies, including better immune function and lower risk of eczema. For example, to prevent atopic dermatitis (the most common form of eczema in babies), early evidence supports taking probiotics during pregnancy.

Evidence for preventing gestational diabetes is more mixed. In women already with gestational diabetes, probiotics may recover normal glucose metabolism. However, regarding prevention, other evidence shows that probiotics don’t stop gestational diabetes developing.

Interestingly, in mice, probiotic administration during pregnancy reduces autism risk. Evidence for autism prevention in humans is less clear, but there does seem to be some benefit.

The vaginal microbiome also needs maintaining during pregnancy 一 research shows that healthy vaginal flora guarantees that the baby, if delivered vaginally, will develop better gut microbiota. The evidence remains inconclusive regarding the effect of oral probiotic supplementation on vaginal bacteria, but some evidence suggests that probiotics do alter relationships between microbiota, suggesting a regulatory role of probiotics for restoring balance.

Interestingly, PRO-Moms chose specific bacterial strains to encourage folic acid production in your gut. Folic acid prevents neural tube defects in your fetus ー we do recommend folic acid supplementation in addition to this probiotic to ingest the correct amount!
