The active form, not just the name
We specify the bioavailable form the evidence is built on, not the cheapest version sharing the label name.
Our standards
The hard part is what we leave out.
Anyone can add ingredients. We built nb1 to refuse the ones that don’t earn their place, to prove the ones that do, and to make it all ourselves, in our own factory. This is where we draw the line.
What we stand on
Four rules. Everything else follows.
- 01
Biology before formula
We understand a body before we decide what to give it. The order is the whole point.
- 02
Evidence over trend
What’s popular doesn’t earn a place here. Published proof does.
- 03
Restraint over more
The shorter formula is the better one, and we’ll leave things out to keep it that way.
- 04
Proof built in
Built from data, measured against data, documented in the batch that reaches you.
Most of the industry competes by adding. We compete by taking things out.
A library of 125+ components, and a single formula typically draws on just 15–25. The rest stays on the shelf, by design. Four rules we don’t break:
No pixie dust
Nothing goes in to look impressive. If it can’t do something your reading calls for, it stays out.
No claim-farming
We don’t pad formulas with vitamins just to unlock authorised health claims. That buys copy, not results.
No evidence, no entry
Every ingredient enters only with published evidence, signed off by our science board.
Nothing you don’t need
You get only what fits you. The best formula is the shortest one that works.
Where it comes from
A component earns its place. So does its source.
Where an ingredient comes from, and in what form, decides whether it does anything at all. A source earns its place the same way an ingredient does, or it doesn’t get used.
Purity specified before a lot is accepted
Every raw material arrives with a spec for identity, potency and contaminants. Lots that miss it are rejected, not blended in.
Suppliers vetted, not just invoiced
We qualify suppliers before a material enters the library, and re-check them over time.
How it’s made
We don’t outsource the part that matters.
Most brands design a formula and hand it to a contract manufacturer. We don’t. Your formula is made in our own facility in Europe, operating to Good Manufacturing Practice, same team, same standard, from library to batch to bottle.
-
Our own factory
Made in-house in our own European facility, not a shared contract line.
-
GMP manufacture
Produced to Good Manufacturing Practice (GMP) standards.
-
Ingredient testing
Every ingredient identity-tested and screened for contaminants before production, in accredited EU labs.
-
Traceable, batch to bottle
Every component documented, raw material to the pack you receive.
Owning production means no contract manufacturer’s minimums and no shared lines, so the restraint above survives into the bottle. Our facility operates to Good Manufacturing Practice; nb1 runs its quality system to ISO 9001. Details available on request.
In every formula
What every nb1 formula holds to.
Beyond what your reading calls for, every formula meets a baseline that never changes. Open any standard for the detail.
Vegan
Every component, and the capsules themselves, are plant-based. No gelatin and no animal-derived carriers.
Allergen-conscious formulation
We formulate to avoid the major allergens wherever possible, and every formula is screened against the sensitivities you tell us about.
No unnecessary fillers or binders
We use only what a dose genuinely needs to hold together. Nothing is added to bulk out a capsule or pad the label.
No artificial colours or sweeteners
Nothing goes in for looks or taste. No synthetic dyes, no artificial sweeteners, no cosmetic additives.
Full transparency on every dose
You see the exact amount of every ingredient in your formula. No proprietary blends, no hidden quantities.
by design
Who vets it
6researchers
on the board
They decide what the library is allowed to contain, including two independent academics with no stake in nb1.
Who decides
Every ingredient is vetted by our science board.
Nothing joins the library until the board agrees the evidence holds, at a dose the research supports. Popularity and trend count for nothing here.
What proof looks like
Proof with your batch number on it.
Standards only mean something if they leave a paper trail. Every formula produces records tied to your batch, from our own factory, yours, not a sample’s.

Ingredient screening
Every ingredient we use is identity-tested and screened for heavy metals and microbial contaminants before it enters production.
- Identity
- 100% tested

Formula sign-off
Before manufacture, each personalised formula is reviewed against your reading and health inputs, and its heavy-metal load is checked for its specific blend and daily serving.

A human approves every build; over-limit blends are blocked
Illustrative of the records each order generates. Your own documents are tied to your batch and available on request. Screening is based on the information you provide and does not replace advice from your doctor or pharmacist. nb1 is a wellness product, not a medical device, and is not intended to diagnose, treat, cure or prevent any disease.
Where to start
Two plans, built to these standards.
Both read your biology and build the formula from it. Advanced just goes deeper, every cycle.
Core
We read your gut, and build your formula from it.
£94 /mo
Prefer no commitment? £99/mo, month-to-month, cancel anytime.
The £94 rate is the 4-month cycle, the window biology needs to shift.
What’s inside
- Your gut, read at species level
- A formula built from your data
- Three components, posted monthly
- Presorted, travel-ready packaging
- Recalibrate on demand
Advanced
Gut and blood. Your formula rebuilds every cycle.
£144 /mo
4 months is the minimum cycle, biology takes that long to shift.
Everything in Core, plus
- Blood biomarkers, alternating with gut
- Formula rebuilds from every analysis
- 125+ ingredient library, on request
- Priority support from the team
Both plans include the analysis and are held to everything on this page. Four months is the minimum cycle; Core also runs month-to-month.
