How Can the Supplement Help?

There are millions of live bacteria living in the GI tract, and these are made of both good and bad ones. This is where probiotic supplements play an essential role in introducing good bacteria to your baby’s stomach.

When your baby’s good bacteria level is down, taking probiotics can help bring back the balance and keep the body working. Probiotics are bacteria and yeasts that are beneficial to the body, especially the digestive tract. So, these good bacteria then fight the bad ones in the gut, which promote better digestive health and help your baby have a healthier immune system.

Since infant probiotics help increase the good bacteria in your baby’s body, it can help lessen stomach problems like colic and gas, so you have a happier and more comfortable baby.

Live Cultures

While probiotics are a type of live culture but not all live culture is categorized as probiotic. This is best explained by OpticBac here:

“When a particular strain of a microorganism undergoes human clinical trials and shows to be of benefit to the human host, only then should it really be classified as a probiotic."

OpticBac also further explains the definition of live culture:

“’Live cultures’ or ‘active cultures’ refer to the microorganisms found in foods such as yogurt, which may be beneficial for human health. The term ‘live cultures’ is sometimes used instead of the word ‘probiotics.'”

The Benefits of Mom and Baby


Naturally, as parents, we want to make sure that our babies get all the best nutrients that they need to be healthy. Giving probiotics may be a new idea to you, but it’s good to know that providing a supplement like this is a natural way of increasing the good bacteria in your baby’s GI tract.

Some doctors believe that those who will benefit most from probiotics are pre-term babies, formula-fed infants or those born through cesarean section because they didn’t get the good bacteria from their mother unlike those who are born vaginally.

Mothers that take probiotics supplements during breastfeeding is also very beneficial to the baby. The goodness of the friendly bacteria will eventually pass from the breast milk to the child. We have written more about this topic in the next post. Click here to read more about it.

Breastfed Infants

After birth, infants continue to receive friendly bacteria from the mother’s milk, but these are called prebiotics. These are indigestible carbohydrates that function as food for probiotics. When the two are combined, they work beneficially to help promote a healthy digestive system in infants.

Breastfeeding is one of the best ways to keep your baby’s GI tract health. Aside from good bacteria, your baby can get immunoglobulin A (IgA) which helps seal the gut’s lining. Doctors believe that children who did not receive healthy bacteria from vaginal birth or breastfeeding will highly benefit from taking probiotics.

For moms that are breastfeeding, consuming probiotic-rich foods will also help you keep your good bacterial health up. These foods are pickles, yogurt, kefir, miso, etc. But, whether your baby takes breastmilk or formula, probiotics are generally healthy and safe for infants and have many benefits for the body.

How Does Gut Flora Affect Health?

Digestive problems

When gut bacteria are not balanced, your baby may experience different digestive issues like colic, acid reflux, constipation, diarrhea, and can even worsen to more serious bowel conditions. Which is why giving probiotics can benefit infants.

Immune system health

There are certain types of bacterial strains that help keep the immune system healthy because there is a lot of interaction between them in our gut. So, without good bacteria in the tummy, the baby can be more susceptible to colds, flu, or other illnesses. Giving probiotics can be a solution to help prevent these.


Giving probiotic supplements to your baby can help them keep a healthy weight. There are healthy bacteria that produce essential nutrients vital for breaking down certain food. Other than that, probiotics may prevent the body from absorbing fat and have it excreted instead.

Skin problems

There have been many studies that show how having a healthy and balanced gut flora can improve skin health. Since baby skin is susceptible to skin problems like eczema, rashes, and baby acne, giving probiotics can help to prevent or enhance present conditions.

How to Give Probiotics to Infants?

For the baby’s early years, the best kinds of probiotics are either liquid or powder. These are the easiest forms your baby will take. Always consult your pediatrician before giving your baby any supplements. It is best to start slow on probiotics and gradually increase until the recommended dosage.

Also, watch out for any bowel changes. Any drastic bowel changes might be a form sign that either the probiotics are not right for the baby or the amount of dosage given is off. In whatever the case is, consult the pediatrician immediately to get advice.

Liquid probiotics

Liquid probiotics can be given directly to your baby or be mixed in a little breast milk or formula. This way of giving supplements to your baby will allow her to get just enough water to not cause an imbalance in his or her electrolytes.

Powder probiotics

Powdered probiotics can also be mixed into a little breastmilk or formula, just like liquid probiotics. When the baby is a little older and starts eating solids, it can be mixed with the food.

Are Probiotics Safe for Newborns?

Just like any probiotics for kids, these supplements are generally safe for newborns. There are even some probiotics that are meant to be taken during pregnancy, while the baby is still in the tummy. Just be sure to consult your pediatrician before you give birth and ask if it’s safe to continue the probiotic supplements.

Common Practice

There are many different ways for you to give your baby the supplements. As we mentioned, it can be added to the milk whether powder or liquid. It can also be given directly to your baby if you are using probiotic drops. The best thing to do is watch your baby’s behavior so you can decide how he or she will effectively take it.

Monitoring the Intake

Probiotics don’t have side effects on infants and it is uncommon to overdose on it. But to keep your baby safe, always consult your pediatrician about the proper dosage. It is best to understand how much and how often you should give it to your baby so that he or she will get the full benefits. Learn more about the best time to give probiotic to children, here.
