OUR STORY
Formulated Without Compromise
Kōjō began because Tom and Ash could not find a supplement worth taking - not one with honest doses, not one they would stake their name on. So they built it.

THE BEGINNING
Formulated Differently
We started from a simple question: why does every supplement either hide its doses or pad them to look impressive? Kōjō is the answer. 50 ingredients, every milligram published, nothing proprietary. Built for people who actually read the label.

THE SCIENCE
Evidence at the Right Dose
Every ingredient decision is backed by peer-reviewed research at the dose the research actually used. We do not cite a study and then use a fraction of the dose. No trends. No guesswork. No filler. If the evidence is not there, neither is the ingredient.

THE STANDARD
Published. Tested. Honest.
Every batch is third-party tested before it ships. We publish the certificates. We use patented, bioavailable forms of ingredients - not the cheapest source. The label tells you everything. There are no shortcuts in the lab.
THREE NON-NEGOTIABLES
Three things we will never compromise
01
Evidence
Every ingredient decision is backed by peer-reviewed research at the dose the research actually used. We do not cite studies and then use a fraction of the dose. No trends, no guesswork, no filler.
02
Transparency
The label tells you everything. The dose. The source. The reason it is there. Tom and Ash take this every morning - if they would not, neither would you. That is not a marketing line. It is how we make decisions.
03
Quality
Every batch is third-party tested before it ships. We publish the certificates. We use patented, bioavailable ingredient forms - not the cheapest source we could find. There are no shortcuts on the label, and none in the lab.
THE FOUNDERS
Built by people who take it
Tom and Ash met at a post-natal class. Both new dads, both asking the same question: what actually works at what dose? Neither could find a supplement that answered it honestly. So they built one.
On reviews: we will not fake them to launch. Reviews arrive when real customers write them. Until then, that space on the site stays quiet. It is how we mean to run this.
“We built the product we had been searching for. Kōjō is that product.”
