kēpos provides powerful prebiotics not found in modern diets. A unique blend of nutrients originally found in human milk to help support, restore, and fortify whole-body health.
restores healthy gut bacteria missing in the average population for improved digestive health
supports iron absorption to combat deficiency and boost daily energy
enriches immune health to help fight sicknesses and harmful pathogens
kēpos is made through a proprietary precision fermentation process that involves zero human milk. This process enables us to make powerful, human-equivalent nutrients from scratch.
Precision fermentation allows us to be highly pure, dosed perfectly for adult health, and free from common sourcing issues in plant and cow-based nutritional products.
Not everything in human milk is necessary for adults, like fats and lactose, which is why we've only unlocked the nutrients clinically-validated for adult health.
These include powerful fibers and glycoproteins that help refresh, rebuild, and fortify your gut and immune health better than plant and cow-based nutrition.
Most of our customers see positive impacts on their gut and immune health with their first month's order. Your digestion may adjust in your first week — this is normal and means kēpos is working.
As the microbiome is a living engine, we recommend at least three months of kēpos to maximize long-term impact.
Yes. In addition to rigorous testing for heavy metal, contaminants, and microbiological activities by ISO/IEC-certified labs, kēpos is manufactured in cGMP and AIB certified, FDA-registered facilities in the USA. We then undergo advanced purity testing (proteomics and metabolomics) at our leading university partner, the University of Chicago.
Human milk bioactives have been clinically proven to be safe in hundreds of human trials, supporting their use as a dietary supplement.
Full-spectrum benefits across
gut, immune, and cognitive axes
Fuel for gut
SELECTIVELY FEED GOOD BACTERIA
HMOs and hmLF selectively nourish beneficial gut bacteria like Bifidobacteria, often depleted in adults. Unlike common prebiotics such as inulin or FOS, which can feed both good and less-desirable microbes, they target balance more precisely.
Šuligoj et al. (2020)
Gut barrier repair
STRENGTHEN LINING, BARRIER INTEGRITY
HMOs and hmLF support gut barrier integrity by reinforcing tight junctions and promoting healthy mucosal regeneration. This cellular support helps maintain resilience and limit permeability. Unlike conventional approaches that only address surface effects, they work holistically to strengthen the gut’s natural defenses and promote digestive well-being.
Boll et al. (2024)
Immune signalling
TRAIN YOUR IMMUNITY AGAINST THREATS
HMOs help fine-tune immune signalling by interacting with gut immune cells. They modulate cytokine release, supporting balanced responses and the development of regulatory T-cells.
Xiao et al. (2019)
Neuroplasticity
MICROBIAL METABOLITES SIGNAL BRAIN
Fermentation of HMOs and hmLF produces metabolites that help increase BDNF, a key factor for synaptic growth. This supports the formation of neural connections, promoting healthy cognitive function and overall brain performance.
Marrocco et al. (2022)
Pathogen defense
LIMIT MICROBIAL OVERGROWTH, SUPPORT CELLULAR DEFENSES
HMOs act as natural decoys in the gut by mimicking sugar receptors on the intestinal lining, making it harder for undesirable microbes to attach. hmLF helps strip away vital nutrients from bad bacteria, delivering it to your body instead. Working together, HMOs and hmLF help signal to the immune system and support balanced defenses.
Dierick et al. (2022)
Motility regulation
SCFA SIGNALING DRIVES COMFORTABLE TRANSIT
Fermentation of HMOs and hmLF produces metabolites like butyrate and acetate that help stimulate intestinal movement and support healthy transit. They also reinforce gut barrier integrity, contributing to a resilient mucosa and gut–nervous system connection.
Onodera et al. (2025)
Inflammation support
BALANCE ACTIVATION & RESPONSE
HMOs and hmLF help reinforce the gut lining by supporting junction proteins that hold intestinal cells together. A stronger barrier helps reduce overstimulation of the immune system, limiting unnecessary inflammatory signals and promoting a more balanced response.
Walsh et al. (2024)
Gut-brain axis
MICROBIOME SIGNALING INFLUENCES MOOD PATHWAYS
HMOs and hmLF support the production of short-chain fatty acids (SCFAs) that act as serotonin precursors. These metabolites help modulate gut–brain communication through the vagus nerve and influence neurotransmitter synthesis, supporting balanced signaling along the gut–brain axis. This activity contributes to healthy stress responses and overall mental well-being.
Hwang et al. (2025)
Not all products are made
for everybody — kēpos is.
ENGINEERED TO BE
SPECIAL DIET-FRIENDLY
Because it’s bio-identical, kēpos is highly digestible and gentle on your gut, delivering bloat-free microbiome support. Designed to be friendly towards IBS, Keto, Carnivore, IBD, Celiacs, gluten intolerance, PCOS, GLP-1, and even lactose intolerance. Consult with a physician if you are allergic to dairy.
RESTORE HEALTHY
IRON LEVELS
Unlike traditional bovine lactoferrin supplements, kēpos’s use of hmLF delivers 2x the bioavailability to help restore healthy iron levels. This chemical potency ensures that nothing gets wasted and maximises value-per-nutrient, all while preventing the typical side effects found when taking bovine lactoferrin, like constipation.
OPTIMIZE FOR
LONGEVITY
With powerful anti-inflammatory mechanisms of action, kēpos supplies the first bio-identical, completely bioavailable gut health supplement in the world. Empower whole-body longevity through your next-generation gut stack, saving you 30% on annual supplement spend.

THE kēpos BREAKDOWN
kēpos is the only bioactive supplement in the world that combines the unique mechanisms of action behind HMOs and hmLF — human-based nutrients perfected by 250,000 years of evolution — like selective feeding, iron sequestration, pathogen inhibition, and a myriad more for your gut, immune, and brain axes.
kēpos was incubated out of the University of Chicago, a globally leading research university with over 100 Nobel Laureates, and founded by friends with a fervor to heal their own digestive issues.
your body rejects about 50% of bovine lactoferrin, the key bioactive in colostrum, found in leading colostrum brands. With kēpos, discover the complete bioavailability of hmLF that was designed, evolved, and nurtured for the human body.
with hmLF, kēpos contains 15x more lactoferrin per dose than leading colostrum brands, delivering greater potency and value for money, as well as reduced allergenicity.
Next-generation health benefits
kēpos evolved for the modern human, whose ancestral health has been compromised by modern diets and deficiencies. Nutrition shouldn't be as hard as our food systems make them to be. With kēpos, go back to the roots of human health with the most precise nutrition that microbiome science has ever delivered. Be reborn.
