Hey, I’m Oliver.
co-founder of kēpos.
Years ago I struggled with a chronic gut health issue caused by food poisoning, which led to:
- Constant bloating
- Irregularity
- Food sensitivities
- Low energy
And more that I won’t bore you with.
Every day felt like a negotiation with my own stomach. The emotional burden of my gut issues was equally bad to the pain in my gut.
I’d try fixing it with all kinds of diets, loose clothing,
or just avoiding social events altogether.
Then everything turned around for me when I read about a special kind of prebiotic in a book—the first one we receive in life.
I became obsessed with its potential.
Before
AfterI tried everything from:
- Low FODMAP
- Elimination diets
- Probiotic pills
- Fiber powders
- Kombucha
- Bone broth
- Gut tests
- Supplements and more
And don’t get me wrong:
Some of those things can be good, depending on the circumstance. But many of them just made me feel worse. And with each failed supplement or doctor visit, I lost hope.
I knew there had to be something out there that was better. Sensitive-friendly, inexpensive, scientifically proven, and effective. But I stopped believing I could find it in a supplement.
So I went looking for answers for a gut health product that wasn’t just:
- A fancy probiotic strain that I couldn’t feel but still cost $80
- A prebiotic fiber that made me WORSE
- A cow-based colostrum that gave me acne and bloating
Was there anything out there?
I became fascinated with nature’s first food: human milk
- Contains hundreds of bioactive nutrients
- Packed with special prebiotics that built our gut health
- #1 studied food in human history, for good reason
- Designed the human microbiome
- Closest thing to a real ‘fountain of youth’
Here’s the problem…
I know what you’re thinking. How do you even get human milk? Is there anything we could do to replicate the source code of human biology? The answer: yes.
That’s when kēpos was born (which is now tens of thousands of gut sufferers strong).
One scoop provides the same prebiotics found in human milk
Made with Japanese fermentation technology, which means no human milk is needed at all. The same fermentation that makes yogurt, beer, or insulin.
And backed by the University of Chicago, with 100+ Nobel laureates.
So what’s actually inside? Just two powerful ingredients.
Two ingredients, one shared history
Zero fillers.

Clinically-validated gut health you’ll actually feel*
1 week
Less bloat fast. kpHMO™ feeds bifidobacteria, the good bacteria that crowd out gas-producing microbes. effera® helps make the gut less friendly to the bad stuff.
1 month
Tolerate more foods. As bifidobacteria rise, your gut can get better at handling foods that used to feel rough. That can include common FODMAPs like pasta, hummus, and onion.
2 months
More regular. A healthier gut ecosystem improves smoother motility and more predictable bowel movements. Less random urgency.
3 months
Stronger immunity. Pathogens that are in the gut are flushed away, and a stronger gut empowers the 70% of your body’s immune cells that live there.
6 months
More energy and no afternoon crash. A renewed gut lining helps support nutrient absorption, so vitamins and other essential nutrients actually deliver to where they need to go.
12 months
Whole-body benefits. A healthier gut helps clear brain fog through the gut-brain axis, supports skin glow, hormone production, and healthy metabolism and weight management.

Here’s what people who’ve tried everything are saying
Maria N.
I have many food intolerances (mast cell disorder and auto-immune disease) and chronic loose stool. While it initially made my symptoms worse, I am now seeing a significant improvement in stool firmness. I have tried so many probiotics and other supplements. This is the first product that is giving me hope for a permanent shift in how my body digests food.
Jen R.
I have been using this for a month and a half and have not had one day of bloating, even when eating foods I'm sensitive too. It also has made me less susceptible to certain foods. I love it, wish I found it sooner.
Leslie M.
I never write reviews but wanted to say thank you. After being on Kepos for about 6 weeks now, I no longer have painful bloating every single day that had been going on for like a year or more. My digestion is better, and for the first month in like 6 months I did not have histamine reactions that caused rashes all over my arms and body during the week leading up to my cycle or during my cycle. I couldn’t believe it. I almost didn’t try it bc I’ve tried so much to help with my gut but at the last minute figured what did I have to lose. It’s also allowed me to eat foods that in the past triggered histamine reactions. Anyway- thank you. I’m looking forward to see how I continue to feel these next few months.
Devon W.
This product has done more for my gut health than I could've imagined! I never knew that I could get such a positive response in such a short time. I certainly recommend this for anyone seeking improvement in gut balance.
Namaste I.
I've had digestive issues for the past 20 years and onto week 2 of taking Kepos my stomach pain is half what it was and I'm more regular than ever in my life!
Our belief:
The human gut has already been solved. We just need to feed it what nature intended it to have.
Not another single-strain probiotic. Not a generic plant fiber. Not a cow-based colostrum product. Not a hyper-restrictive diet.
And I know how hard gut routines are to stick with.
Gut health is emotionally taxing. Sometimes we forget to take our supplements. Sometimes they’re chalky, gritty, or uncomfortable to take.
That’s why we’ve made it easy. kēpos has a natural, melt-in-your mouth cotton candy flavor. It’s subtle, light, and feels like a treat.
Customers say they have to stop themselves from taking more than one scoop per day.
Or if that’s not your thing, you can mix it into water where it dissolves easily without a noticeable flavor.
And don’t forget your free stick packs, notebook, and dietitian guide that comes with each order.

We aren’t kidding. It takes 4 months to create kēpos and unexpected demand has strained our supply.
Reclaim your gut healthHow human guts thrived before we trusted random supplements over nature’s first prebiotic superfood
These prebiotics have nourished us from day one, for generations and generations, for all of history.
They’re the 4th most abundant ingredient in human milk. There’s a reason they’re there.
They selectively nourish bifidobacteria, our native gut bacteria that helps us live longer, supports digestion, protects against infection, and reduces bloating. And today? 76% of Americans are deficient.
But that’s not all they do. They flush out bad bacteria and pathogens that are feasting on our gut lining by mimicking the sugar receptors there. That’s right: we evolved so closely alongside them that they have receptors that match the structure of our gut walls!
But I won’t bore you with all the details.
So what’s the problem? Modern supplements are just approximations for what the human gut needs.
Highly processed food. Stress. Environmental factors. Antibiotics. Our microbiome diversity has been wiped out by decades of factors outside of our control.
The proposed solutions: supplements without clinical research, probiotics that maybe work for a week and then stop, prebiotics that fuel overgrowth in the gut, colostrum made for cattle, or enzymes that don’t target the root issue.
None of this was originally designed for the human body.
At kēpos, we believe that these prebiotics are the key to filling the gaps modern diets leave behind.
By giving your gut the nutrition it evolved with, we're going back to our roots.
Fully bio-identical. Made to work in as little as 2 weeks. With a 90-day money-back guarantee.
We're creating the future of gut health by going back to the very beginning.

kēpos begins to work in as little as two weeks. With daily use over the course of three months, expect to see significant improvement in your gut health, energy, ferritin and iron levels, and immune health.
Take one scoop per day at any point, with or without food. If you’re sensitive to gut health supplements, begin at a half scoop per day with food for one week. For added benefits, increase intake to 2 scoops per day.
When dry scooped, kēpos has a nostalgic, melt-in-your-mouth cotton candy note—without any natural flavors, sweeteners, sugar, or additives of any kind. It's subtle, delicate, and turns each scoop into a small treat. If you prefer an unflavored experience, simply mix it into your beverage of choice.
kēpos is an award-winning, daily prebiotic supplement built out of the University of Chicago. With 100+ Nobel laureates, the standard for our science is higher.
kēpos uses ingredients that are structurally the same as the human body, a breakthrough we call ‘bio-identical.’ Because of this, they are faster-acting, better-tolerated, and more effective than other supplement ingredients.
Unlike other gut health supplements, kēpos offers a dual approach: restore the good, remove the bad. kēpos is a special prebiotic that selectively nourishes good gut bacteria, like bifidobacteria. These bifidobacteria produce postbiotics like butyrate that help repair the gut lining, while improving the acidity of the colon to fight off bad bacteria. At the same time, the ingredients within kēpos sequester iron—which many harmful bacteria require to grow—and deliver it to your bloodstream instead for improved energy and ferritin. All while supporting whole-body health, including joint health, memory and mood, muscle growth, and more.
kpHMO™ (human milk oligosaccharides): a powerful prebiotic that restores good gut bacteria and the gut lining. Identical to the prebiotics that first built the human microbiome.
effera® (human lactoferrin): A ‘miracle molecule’ that fights pathogens in the gut and replenishes iron. Identical to the superfood that first built the human immune system.
