The gut microbiome is interconnected with the entire body

Activity in the gut influences the whole body. Gut bacteria individually and collectively send signals to other systems and processes, affecting how they work.

Breast milk nourishes baby — and microbiome

Groundbreaking research discovered breast milk contains special nutrients called Human Milk Oligosaccharides (HMOs), intended to nourish a specific bacterium called B. infantis. HMOs cannot be digested by baby but reach the location where bacteria reside. When B. infantis is present, it uses the HMOs to thrive and provide support to the gut and immune systems.*

Ongoing and high levels of detection, meaning the microbe must be actively replicating to establish an ongoing presence within the gut.

Human milk oligosaccharides

Complex milk sugars that make up the third most abundant solid ingredient in breast milk. HMOs are food for specific good bacteria, primarily B. infantis, to benefit health.
