Microbiome diversity

Selectively feeds good bacteria necessary for whole-body health.

Bloating response

Helps reshape the microbiome to produce fewer bloat-causing gasses, like hydrogen and methane.

Gut barrier repair

Supports the gut barrier by peeling off pathogens and patching gaps.

Digestive regularity

Feeds the bacteria that regulate smooth, consistent bowel movements.

Food intolerance

Reinforces the gut barrier to prevent undigested particles from triggering immune responses.

kēpos arrives as a familiar face

Human milk bioactives are recognized by the body as native compounds. They pass through digestion without triggering immune defense and reach the gut fully active.

The bifidobacteria “key”

Think of HMOs and Bifidobacteria. HMOs are complex sugars that are "padlocked", where only Bifidobacterium have the key. Harmful microbes literally cannot access them, paving the way for beneficial bacteria to thrive.

The decoy effect

HMOs mirror the sugar structures lining your gut wall. Pathogens bind to these decoys instead of intestinal cells and are carried out of the body.

Iron-binding power

Lactoferrin binds free iron in the gut, removing a critical resource pathogens need to grow while making iron more available for the body.

Microbiome self-regulation

Human milk bioactives restore the biological signals that guide microbial balance, helping your gut return to a sustainably resilient state.

The gut-building power of human milk

Powered by

Benefits of kēpos

Your gut lining, microbiome, and bloating are connected. kēpos targets all three.

Rebalance gas-producing bacteria
Bloating
GI Discomfort
Quality of Life

In a landmark University of North Carolina study on human milk oligosaccharides, 88% of 245 completed participants experienced clinically significant digestive improvements — including a 59% reduction in bloating, 55% less GI discomfort, 60% less abdominal pain, and 48% better quality of life.

Selectively feed keystone bacteria
Bifidobateria

In a randomized, double-blind clinical trial at Stanford University, participants saw ~3x greater Bifidobacteria levels compared to placebo by week 3, a 6% increase in HDL—the "good" cholesterol—and substantially improved visual memory, with Bifidobacteria relative abundance reaching ~20%.

Patch gaps in intestinal lining
claudin-8
claudin-5

Human milk oligosaccharides significantly increased claudin-5—a key protein responsible for strengthening and upregulating your gut barrier—by up to 8.25x, increased claudin-8 by up to 6.13x, and reduced overall gut permeability by 41–44% in a preclinical study at the Quadram Institute.

Wholesomely kēpos

Your gut didn’t break overnight. kēpos works the way nature intended, layer by layer, from the inside out.

A real reset has a timeline. Here’s yours:

The gut is human.

The solution should be, too.

kēpos is built on the exact bioactives the human body has evolved to thrive on.
