Yuzu-matcha. Light, clean, slightly earthy. No artificial sweeteners. The flavour was developed alongside the formula. Compliance only works if you look forward to taking it every morning.

Most people find it easy to drink. A small number find the matcha earthiness takes a day or two to get used to. Stick with it.

Yes. Every batch is independently tested by an accredited laboratory before it ships. The Certificate of Analysis (CoA) is published. Scan the QR code on your pouch. What is on the label is what is in the product.

The current version is v4.1, launched in 2025. It includes 50 ingredients with creatine confirmed at 5,000mg and a Certificate of Analysis programme covering every batch.

Every change to the formula is documented on the formula history page with the reason it was made. The formula improves when the evidence improves. That is the only reason to change it.

Yes. The formula is designed to replace a full supplement stack, creatine, magnesium, vitamin D3, K2, B complex, adaptogen, CoQ10, probiotics, and more, in a single daily scoop.

Most people taking it find they can stop buying 6 to 10 separate products. See the full ingredient list →

Because most supplements use doses below what the research actually used. Rōnin matches the clinical trial doses. The amounts that produced the measured effects in peer-reviewed studies.

A sub-clinical dose may not produce the same result. See our research references →

A Certificate of Analysis (CoA) is a document from an independent, accredited laboratory confirming that a batch matches its stated contents. Ingredients, doses, contaminants, and purity. It is the standard by which pharmaceutical manufacturing is verified.

Most supplement brands do not publish CoAs. KōJō does, for every batch. Scan the QR code on the pouch or email hello@kojo.life for a specific batch document.

Generally yes. The formula is comprehensive by design, so check for overlap before adding anything else to your routine. If you are already taking creatine, vitamin D3, or magnesium separately, you may not need to continue. The formula covers all three at clinical doses.

Check the full ingredient list before stacking to avoid duplicating doses. If you are unsure, email hello@kojo.life.

Speak to your GP before starting any new supplement if you are taking prescription medication. Some ingredients, rhodiola rosea, for example, can interact with certain antidepressants and medications that affect serotonin levels.

We would always rather you check first. The full ingredient list with sources is on the formula page.

Week 1 to 2: Most people notice cleaner energy and sharper focus. The B vitamins, magnesium, and adaptogens work relatively quickly.

Week 4 to 6: Sleep quality and stress baseline begin to shift. Bacopa and rhodiola take longer to accumulate. Bacopa especially benefits from the full 8–12 week window.

Week 8+: The full picture. Creatine, CoQ10, and the long-acting ingredients reach steady state. Supplements compound. Give it the time.

One scoop (~30 g) in the morning. Mix with 250 to 300 ml of cold water. A shaker or tall glass works well. Takes about 20 seconds.

Ideally with food: the 66 mg caffeine and 5 g creatine sit easier with a small breakfast, though consistency matters more than timing. Same time every day, however you take it.

Yes. Many people do, and most are fine. We recommend taking it with food for best tolerance (the 66 mg caffeine and 5 g creatine sit easier with a small breakfast). If you take it fasted and feel any mild nausea (rare, usually from the high-dose B vitamins), switch to with breakfast.

Yes. The formula is fully vegan. The vitamin D3 source is algae-derived (not lanolin). All other ingredients are plant, mineral, or synthetic origin. No animal-derived ingredients, no gelatine capsules.

Yes. And the combination is intentional. Several ingredients in the formula (magnesium bisglycinate, L-theanine) directly support HRV and stress response, which are the same physiological pathways that structured breathwork targets.

Tom and Ash. Two people in their 30s who spent years reading the same research independently and could not find a supplement that used it honestly. They built KōJō for themselves. Both take it every morning.

KōJō is derived from the Japanese concept of continuous improvement. The idea that the formula, like the person taking it, is always getting better. Formula v4.1 is the best version yet. It will not be the last.

KōJō publishes every milligram of every ingredient on the label, with no proprietary blends and no superfood-powder filler. We use clinically-relevant doses derived from the same trials we cite.

A standard multivitamin covers a handful of basic vitamins and minerals at maintenance doses. Rōnin is fifty actives across nine categories. Vitamins and minerals at trial-grade doses, plus adaptogens, amino acids, antioxidants, polyphenols, gut and cognitive support. It replaces the multivitamin and the stack you would otherwise build around it.

Greens powders are usually marketed on green-colour aesthetic and use under-dosed plant extracts. Rōnin is a daily formula. The greens that matter (matcha, moringa, mint) sit alongside the vitamins, minerals, and adaptogens that move biomarkers. See the full ingredient list →

Ashwagandha causes problems for a non-trivial subset of users (gastrointestinal, hormonal, hepatic flags in the literature). We chose Rhodiola. Better tolerated, well-evidenced for adaptogenic effect. Iron we omit deliberately. Supplementation outside diagnosed deficiency is associated with elevated oxidative stress and is not appropriate as a daily formula. See the philosophy that drives ingredient inclusion →

Yes. Rōnin is manufactured in a GMP-certified (Good Manufacturing Practice) facility. Every batch is third-party tested for purity, potency, and contaminants. The Certificate of Analysis (CoA) is available on request and published per batch.

Vegan, gluten-free, dairy-free, soy-free, sugar-free. Sweetener is xylitol, used at low levels for tolerability. Full nutritional and allergen detail →
