Rebuilding your microbiome

The problem

The modern gut has gaps. Antibiotics, ultra-processed food, chronic stress, and low fiber have damaged our microbiomes. Standard gut health products can't rebuild what's been lost because they don't know how.

The formula

kpHMO™ is molecularly identical to the powerful prebiotic fibers found in human milk—the exact compounds nature uses to establish a healthy microbiome from scratch. In clinical data, these fibers replenish Bifidobacteria and flush away pathogens.

kēpos works differently.

Powered by kpHMO™, a one-of-a-kind prebiotic that your gut recognizes as native. Bioactives you can't find anywhere else, with benefits that probiotics, prebiotics, colostrum, greens, and enzymes can't match.*

01. Target, fuel, restore

Selective feeding

kpHMO™ exclusively fuels Bifidobacteria—the keystone probiotic you lose with age—without feeding the harmful bacteria that other prebiotics fuel.

*PMID: 27719686

02. Detach, bind, flush

Pathogen decoy

kpHMO™ mimics the chemical structure of your gut lining, causing harmful bacteria to detach from your intestinal wall, bind to kpHMO™ instead, and get flushed.

03. Bind, sequester, deliver

Iron sequestration

Human lactoferrin binds free-floating iron away from pathogens in your gut, both starving them and delivering bioavailable iron into your bloodstream.

04. Contact, coach, defend

Immune coaching

Human milk bioactives directly contact the dendritic cells lining your gut, training your immune system to respond precisely to real threats, and stand down from everything else.
