I Like Baby Guts…and I Cannot Lie: Effects on Gut Microbiome When Supplementing

Kristen Howorko, BSN, RN, IBCLC
Course description
When a parent is not producing enough milk for their child, supplementation with donor human milk or infant formula is medically necessary to meet the infant’s nutritional needs for growth and development. Within the lactation profession, a narrative has become the norm that supplementation with donor human milk or infant formula has an intense impact on the infant’s microbiome and can lead to long term negative health outcomes. Current research suggests that this is not entirely the case. In this presentation, the Learner will gain evidence-based information on the infant gut microbiome and how raw human milk has the ability to protect the infant microbiome despite supplementation with formula or human donor milk. Additionally, the presentation will discuss two specific studies that break down the differences in microbial diversity in preterm infants and term infants with different feeding methods. By the end of the presentation, the Learner will be able to effectively communicate with clients/patients regarding topic of gut microbiome when supplementing.

Kristen Howorko, BSN, RN, IBCLC

I am a Board Certified Lactation Consultant and Registered Nurse. I worked in a Level III NICU as an RN on a 50 bed unit at the University of Colorado Hospital, and have worked as a Lactation Consultant in the same NICU for the past 3 years. In February of 2020, I started Milk'd Up, which is a family-centered lactation practice that strives to empower parents to feel confident feeding their babies. We are an inclusive practice that supports ALL infant feeding goals. When I am not helping moms, I like to spend time reading, running, skiing or doing yoga.

Kristin had me at “if you are lucky enough to poop during delivery.” Great talk, and led to many thinking points as research continues to evolve about baby guts and which food we put in them. 

-Lauren M., RN IBCLC 

This was a a fantastic workshop! It was very clearly presented and balanced the science with how to communicate with families. Loved it! 

-Rhegan D., IBCLC, MSW

Very well researched and informative.

Knowledge Gap
The impact of supplementation on the infant microbiome is an evolving area of research. This presentation is going to provide participants with a basic understanding on infant gut microbiome and outline the current research on the impact of supplementation on the infant microbiome.


Describe the current physiological processes occurring in the gastrointestinal tract that support microbial growth and development. 


Examine the impact of supplementation on the infant gut microbiome. 


Describe the clinical significance of changes that occur in the infant gut microbiome as a result of supplementation.


List at least one way that you can integrate information on supplementation’s impact on the infant gut microbiome into your private practice.
