Strain, AFU & honesty.

Why Akkermansia and inulin carry no authorised health claims, what AFU and "prebiotic" actually mean, the difference between pasteurised and live, and a five-check framework for comparing microbiome supplements honestly — the named strain over the marketing.

Quick answer
How should you compare Akkermansia supplements?
There are no authorised UK/EU health claims for Akkermansia muciniphila — so an honest product won't promise outcomes. That's a regulatory status, not a scientific verdict. The genuinely useful way to compare microbiome supplements is on four things: the named species and strain, the stated count and its unit (AFU or CFU), the form (live or pasteurised), and independent testing. Marketing language describes a category; a precise label describes a product.
Key takeaways
  • No health claims are authorised for Akkermansia or inulin in the UK/EU — a regulatory status, not a verdict on the research.
  • Novel food authorisation (which pasteurised Akkermansia holds) is a safety status, not a health claim.
  • AFU and CFU measure cells differently and are not directly comparable.
  • The inulin bowel-function claim needs ~12 g/day — far above a 390 mg serving — so we don't rely on it.
  • Compare on named strain, count + unit, form, and independent testing.
  • Claim-free language is a good sign; outcome promises for Akkermansia are a red flag.
The regulatory position

No authorised claims — and why that's fine

A claim being "unauthorised" doesn't mean a thing has been disproven. It means it hasn't been through the approval process — a status, not a verdict. Under the GB and EU nutrition & health claims framework, a supplement may only state a specific health benefit if that exact claim has been authorised on the official register. For Akkermansia muciniphila, no health claim is authorised — so a responsible brand describes what the organism is and what research has investigated, and stops there.

Two things often get blurred and shouldn't be. First, novel food authorisation is not a health claim: pasteurised Akkermansia muciniphila is authorised as a novel food in GB and the EU, which is a safety and market-authorisation status, and it permits no benefit claim. Second, inulin's narrow claim doesn't apply here: an authorised claim exists for native chicory inulin tied to a high daily intake (around 12 g/day) for bowel function — a 390 mg serving is far below that threshold, so we don't, and can't, rely on it.

Unauthorised is a status, not a verdict — so we describe, and don't promise.
The count, honestly

AFU vs CFU — and why you can't compare them

This is where labels get confusing. Two products can both show a big "billions" number and be measuring completely different things. So 30 Billion AFU is not "more" or "less" than 30 Billion CFU — it's a different measurement. Honest comparison means checking the unit, not just the number, and being wary of a label that shows a count with no unit at all, or hides the count behind a "proprietary blend" weight in milligrams.

CFU
Colony-Forming Units. Counts cells that grow into colonies on a plate. Standard for easy-to-culture probiotics; undercounts hard-to-culture species like Akkermansia.
AFU
Active Fluorescent Units. Counts intact cells directly by fluorescence flow cytometry — including pasteurised cells that won't form colonies at all.
The pasteurised wrinkle
Why AFU here. Pasteurised cells are non-viable, so they'd register as zero by CFU — yet they're intact and present, which AFU captures.
Read the unit
The honest check. A number means nothing without its unit. No unit, or a count hidden in a blend weight, is a red flag.
The form

Pasteurised vs live

Akkermansia comes in two forms, and a transparent label tells you which. Live cells are viable and can colonise; pasteurised cells are heat-treated and non-viable, but intact and still counted by AFU. Pasteurised Akkermansia muciniphila is the form that holds novel food authorisation in GB and the EU.

Neither form is automatically "better" in a way anyone is allowed to claim — what matters is that the product states the form plainly, so you know what you're buying and can compare like with like.

The framework

How to compare microbiome supplements honestly

Five checks that cut through marketing — usable on any brand, including ours. Microbiome research is strain-specific, so the single most honest signal on a label is precision: the exact species and strain, named, with a count, a unit and a form.

  1. Is the species and strain named?

    Look for the exact organism — Akkermansia muciniphila — not just "probiotic complex" or "gut blend".

  2. Is there a count with a unit?

    A number means little without AFU or CFU attached. Be wary of counts hidden inside a proprietary-blend milligram weight.

  3. Is the form stated?

    Live or pasteurised — they're counted and handled differently. The label should say which.

  4. Is it independently tested?

    Third-party or accredited batch testing for identity and count turns a label number into a verified one.

  5. Is the language claim-free?

    Honest copy explains what the organism is and what research has investigated. Unauthorised outcome promises for Akkermansia are a red flag.

Marketing describes a category. A named strain, count, unit and form describe a product.
Common questions

Honesty, answered

Because no health claim for Akkermansia muciniphila is authorised under UK/EU rules, and we only state what's authorised. That's a regulatory position, not a judgement on the research — so we describe what the organism is and what studies have investigated, and leave outcome promises off the page.
Yes — pasteurised Akkermansia muciniphila holds novel food authorisation in Great Britain and the EU. That's a market-authorisation and safety status, separate from any health claim, which still isn't permitted.
They aren't directly comparable — AFU and CFU measure cells in different ways. AFU (fluorescence flow cytometry) suits hard-to-culture and pasteurised cells; CFU (plate colonies) suits easy-to-culture live probiotics. Compare the unit, not just the number.
There's a narrow authorised claim for native chicory inulin tied to a high daily intake (around 12 g/day) for bowel function. A 390 mg serving is well below that level, so we don't rely on it or make any claim from it.
Named species and strain, a count with its unit (AFU or CFU), the form (live or pasteurised), and evidence of independent batch testing. Claim-free language is a good sign; outcome promises for Akkermansia are a red flag.
Because microbiome products are easy to over-sell and hard to verify. We'd rather give you the tools to compare honestly — even against us — than lean on marketing language we couldn't stand behind.
