One Drawback of Modern Medicine When it Comes to Infant Health

Ten fingers, ten toes, that intoxicating new-baby smell—your little one is perfect. But her gut microbiome is very likely missing something that all babies used to have: a special strain of good bacteria called B. infantis.


B. infantis plays a key role in a healthy gut, which in turn leads to the development of a healthy immune system. But the unintended consequences of some modern medical practices have caused B. infantis to go missing from the gut microbiomes of babies, particularly in the US and other developed nations.

You can provide B. infantis to baby with a special probiotic called Evivo, which is clinically proven to restore B. infantis to your baby’s gut microbiome. But first, it helps to know why B. infantis is important, and why your baby is missing it.

What is B. infantis?
The “gut microbiome” is just the name for all the bacteria that live naturally in your baby’s gastrointestinal system, her stomach and intestines. These bacteria break down and digest breastmilk, plus they prevent harmful microbes and germs from implanting into the gut lining and making the baby sick.

One crucial strain of good bacteria is called B. infantis, and it feeds on a special component of breastmilk called human milk oligosaccharides, or HMOs. There are more than 150 HMOs in breastmilk, and B. infantis consumes HMOs and flourishes, crowding out bad bacteria. As a little side bonus, the process results in extra usable nutrition for the baby, too, in the form of fatty acids.

Why do modern babies lack B. infantis?
At birth, a baby is inoculated with bacteria from her mother. That bacteria used to always include B. infantis—it made up a huge part of the baby gut microbiome. And in developing countries, it still does. Babies born in places like Malawi and Gambia have plenty of B. infantis occurring naturally, and the associated reduction of bad bacteria in the gut microbiome is credited for a reduced risk of allergies, childhood diabetes, colic, and eczema.

But in industrialized countries like ours, modern medical practices have had the side effect of reducing how much B. infantis occurs naturally. In fact, B. infantis can be effectively missing from the gut micromes of up to 97 percent of babies born in developed countries today. It’s thought that the rise of antibiotics, antibacterial products, C-sections, and infant formula has led to this change, although obviously those advancements have brought plenty of benefits, too.

How to bring B. infantis back
Parents want to give their babies everything, and thanks to Evivo, you can give your baby the B. infantis missing from her gut. Evivo is a powdered probiotic containing live, activated B. infantis, specially formulated to mix with breastmilk and unlock all the potential of those HMOs and the rest of the nutrients that make breastmilk so amazing.

Parents can mix a pack of Evivo with a few milliliters of breastmilk and dropper-feed it to the baby once a day, for as long as she’s still breastfeeding. It’s clinically shown to restore B. infantis to baby’s gut microbiome—the way it used to be.
