Breast Milk & Your Baby’s Gut – The Important Link

Breastmilk is the healthiest thing you can feed your baby, but did you know it’s actually doing double duty? Breastmilk doesn’t just feed the baby—it also feeds her immune system.


Breastmilk does contain nutrition for your baby, in the form of fats, carbs, vitamins, even hormones and antibodies. But some of its most special ingredients can’t be digested by the baby. Special sugars called human milk oligosaccharides, or HMOs, are actually there to feed the bacteria found in your baby’s gut microbiome.

Home of the immune system
Everyone’s gastrointestinal tract, or gut, is full of bacteria. We need these bacteria to break down the food we eat, for example, so the body can convert it to energy. There are both “good” and “bad” bacteria in the gut. B. infantis is a special strain of “good” bacteria that should dominate the baby’s gut for developing metabolism and immune system, but the gut can also host “bad” bacteria like E. coli that can make us sick. All the bacteria found in the gut are known as the gut microbiome.

Babies get their gut microbiome from their mothers, and the HMOs in breastmilk feed the good bacteria. The good bacteria B. infantis gobbles up the HMOs, converting all to nutrition the baby can actually use. Good bacteria also protect the lining of the gut, preventing bad bacteria, germs, and viruses from being able to attach and make the baby sick.

A healthy gut microbiome and reduction of bad bacteria is linked to fewer instances of colic, asthma, allergies, obesity, and diabetes, plus it promotes a healthy metabolism. If there are too many bad bacteria in the gut microbiome, they will crowd out the good bacteria, and the HMOs in breastmilk will go undigested, or wind up feeding the bad bacteria instead.

The role of probiotics
Most babies born in developed countries today are missing B. infantis in their gut microbiome. It used to appear naturally, but over time, the unintended consequence of increased use of antibiotics, C-sections, and formula have caused B. infantis to go missing from the gut microbiomes of up to 97 percent of babies.

Fortunately, you can put B. infantis back in your baby’s gut with a special probiotic called Evivo™. Evivo contains a live strain of B. infantis, and it’s designed to be mixed with breastmilk and fed to your baby once a day.

Putting B. infantis back in your baby’s gut with Evivo helps unlock the full potential of the HMOs in breastmilk. It promotes a healthy immune system and better metabolism.

Evivo gives your baby a head start on a healthy immune system. It is clinically proven to restore baby’s gut to its original, natural state. To find out more, visit
