Probiotics and Eczema

Listen up all you pregnant and breastfeeding moms who suffer from allergies, eczema, hay fever, or allergy-related asthma…a recent study shows if mom takes specific probiotics while pregnant and breastfeeding, baby’s risk of developing eczema during the first 24 months of life is significantly reduced. 

That's great news!  There are literally hundreds of strains of probiotics and each have various functions. The two strains shown effective in this particular study are Lactobacillus rhamnosus and Bifidobacterium longum (1). The good news is, this is not the first study to show a relationship between mom taking probiotics during pregnancy and baby’s reduced risk of allergy (2, 3).

Here’s how probiotics works: 

Your gut is home to billions of bacteria, good and bad.  Probiotics colonize the intestines with good bacteria and ultimately keep the bad bacteria from multiplying. When harmful bacteria take over, it is associated with a weakened immune response, possibly leading to the development of allergic reactions, autoimmune disorders (ie: ulcerative colitis, Crohn’s disease), and infections (ie: diarrhea, H. pylori, skin infections), to name a few. 


Need another reason to consider adding probiotics to your pregnancy diet? Perhaps no group has as many digestive issues as pregnant women! Whether it's heartburn, constipation, cramping, or diarrhea, pregnancy comes with a host of digestive ailments. No fun at all! Probiotics promote healthy gut function, which aids in relieving some of these very common problems pregnant women face. Probiotics shown to improve constipation include: Bifidobacterium bifidum, Bifidobacterium lactis, Bifidobacterium longum, Lactobacillus casei, Lactobacillus plantarum, and Lactobacillus rhamnosus (4).

What foods contain probiotics?

Probiotics are most often found in fermented foods. The most common sources include yogurt and yogurt drinks, kefir (a fermented milk drink), acidophilus milk, cheese, and sour cream. Miso, tempeh, sauerkraut, kimchi, kombucha drink, and some juices may also contain probiotics.

How to take a probiotic supplement:

Supplements don't provide the same nutrition whole foods can offer, but they can be convenient. I personally have had excellent experience with this probiotic, and it contains all probiotic strains important for reducing eczema in infants and relieving constipation. 

Always take your probiotic about 5-10 minutes after dinner and refrigerate your probiotic.

Taking probiotics while pregnant is quite safe (5); however, it is still important for pregnant and breastfeeding women to consult with their physician before using a probiotic supplements.

Does anyone have anything to share regarding probiotic use during pregnancy?
