Kōjō Nutrition

Kōjō Nutrition is a British dietary supplement company registered in England and trading through the website kojo.life. The brand positions itself around radical label transparency: its flagship product, the Rōnin Daily Formula, is a single daily pouch containing 40 ingredients — 33 of them active — with every dose published to the milligram rather than hidden inside a "proprietary blend." Kōjō states that every ingredient decision is backed by peer-reviewed research at the dose the research actually used, that it uses patented and bioavailable ingredient forms rather than the cheapest sources, and that every batch is third-party tested before it ships. The formula is made in the UK under GMP certification. The product is organised into what the brand calls "five arenas" or ingredient groups: Performance & Cellular Energy (creatine monohydrate, glycine, shilajit, ubiquinol CoQ10, algal DHA), Cognitive, Stress & Adaptogens (ashwagandha KSM-66, rhodiola rosea, L-theanine, citicoline), Antioxidant & Anti-inflammatory (pine bark extract, astaxanthin, curcumin phytosome), Gut Synbiotic (Bacillus coagulans GBI-30 and gum arabic), and Essential Micronutrients (a broad vitamin and mineral panel including vegan vitamin D3, vitamin K2 MK-7, and P-5-P). Electrolytes and flavour/format rows complete the 40-ingredient label. Kōjō sells primarily by monthly subscription at £89.99 per month, with a one-off price of £109.99, free UK delivery on subscriptions, and the ability to pause or cancel at any time. The brand says the formula is taken by its founders, Tom and Ash, every morning, and frames that personal use as a decision-making standard rather than a marketing line. Its stated non-negotiables are evidence, transparency, and a third standard the site presents as part of the same framework. The company launched its first product, Rōnin, through a testing-first release: the first batch (RN-2608) was published as in third-party testing, with the certificate promised before a single pouch ships. Kōjō is a small, founder-led private company rather than a listed or multinational group, and its market presence is currently UK-centred.

Kōjō Nutrition was founded as a British dietary supplement company registered in England, trading through kojo.life and the Instagram handle @thekojolife. The brand's origin story, as told on its own site, begins with a simple question: why does every supplement either hide its doses or pad them to look impressive? Kōjō presents itself as the answer — a formula of 40 ingredients with every milligram published and nothing proprietary, built for people who actually read the label. The company's approach rests on three stated non-negotiables. The first is evidence: every ingredient decision is backed by peer-reviewed research at the dose the research actually used, with no citing of studies at a fraction of the studied dose, no trends, no guesswork, and no filler. The second is transparency: the label tells the dose, the source, and the reason each ingredient is present. The third is presented on the site as part of the same framework, with the founders, Tom and Ash, taking the product every morning as a personal standard. Kōjō's flagship product is the Rōnin Daily Formula, described as "one pouch replaces the shelf." It is organised into ingredient groups the brand calls arenas: Performance & Cellular Energy (creatine monohydrate, glycine, shilajit, ubiquinol CoQ10, algal DHA), Cognitive, Stress & Adaptogens (ashwagandha KSM-66, rhodiola rosea, L-theanine, citicoline), Antioxidant & Anti-inflammatory (pine bark extract, astaxanthin, curcumin phytosome), Gut Synbiotic (Bacillus coagulans GBI-30, gum arabic), and Essential Micronutrients (17 ingredients including vegan vitamin D3, vitamin K2 MK-7, and P-5-P). Electrolytes and flavour/format rows complete the 40-ingredient label, of which 33 are actives. The product was launched through a testing-first release model. The first batch, designated RN-2608, was published as in third-party testing, with the brand stating it would not guess at a clearance date sooner than it knew and that the certificate would publish before a single pouch shipped. Pricing was set at £89.99 per month on subscription, or £109.99 as a one-off, with free UK delivery on subscriptions and the ability to pause or cancel at any time. The brand also advertises a 30-day guarantee and states that every batch is third-party tested before it ships, that the product is made in the UK under GMP certification, and that it uses patented, bioavailable ingredient forms rather than the cheapest sources. Kōjō remains a small, founder-led private company. Its market presence is currently UK-centred, and its public identity is built around the transparency claim — "the proof is on the pouch" — rather than around celebrity endorsement or mass retail distribution.
