Pasteurized vs Live Akkermansia: What Formulators Should Know
Quick answer
Live Akkermansia contains living cells that must survive production, storage and use, so it is usually handled under tight oxygen, moisture and temperature control and measured in CFU. Pasteurized Akkermansia is heat-inactivated, stable at room temperature and measured as total cells (TFU/g). Both forms have been studied, so the better choice depends on your format, shelf life, claims and the regulatory route in your market.
How do the two forms differ at a glance?
| Factor | Pasteurized (heat-inactivated) | Live |
|---|---|---|
| Cell state | Cells intact but cannot multiply; culturable count below 10 CFU/g for AKM Lab-01 | Living cells intended to remain alive until consumption |
| Potency unit | Total cells (TFU/g or similar), not CFU | CFU, which depends on survival |
| Oxygen sensitivity | Not a survival issue | The species is strictly anaerobic; oxygen exposure reduces survival |
| Storage | 36-month shelf life at room temperature for AKM Lab-01 (specification) | Depends on the product; ask the supplier for storage conditions and stability data |
| Formats | Capsules, tablets, stick packs, gummies, liquids, solid beverages | Narrower: heat, water activity and acid can all reduce survival |
| Label potency at end of shelf life | Same unit as at release; total cells measured in the stability study | Stability data must show living cells remaining at the end of shelf life |
| EU route | Pasteurised A. muciniphila has an authorisation under Regulation (EU) 2022/168 | Confirm the status of the live form with your regulatory advisor |
| Research | Human pilot (different strain) and preclinical work | Human pilot (different strain) and preclinical work |

Why does survival matter so much for the live form?
A live probiotic only counts as live if the cells are alive when they are eaten. A. muciniphila is an oxygen-sensitive anaerobe, so each step from fermentation to packaging has to protect it. Every blending, tableting, depositing or heating step is a chance to lose cells, and the label count has to be backed by stability data at the end of shelf life.
Pasteurized material removes that variable. The cells are already inactivated, so the manufacturing question becomes whether the finished matrix is chemically and physically stable, not whether the cells are still alive.
Is one form proven to work better?
Not for human outcomes. Depommier et al. (2019) studied the species in volunteers, including a pasteurized group, in a proof-of-concept study and reported on safety and tolerability. It was a pilot and used a different strain from AKM Lab-01.
For AKM Lab-01, the published mouse work (Huang et al., 2026) examined live and pasteurized forms and reported that both were effective in the model. That paper is preclinical and was written mainly by company authors, so read it as supporting context, not as evidence of an effect in people. We make no efficacy claims for either form.
How should potency be compared?
Do not compare CFU and TFU directly. CFU counts only cells that can form colonies, and for a pasteurized powder that number is intentionally close to zero. TFU counts total cells. A supplier quoting “billions of CFU” for one form and “trillions of cells” for another is not describing the same thing.
Ask for the method, the unit, the specification range for each grade and the measured value on the batch COA. For AKM Lab-01 the specified total-cell ranges are 2.0–6.0×1011 TFU/g for the 2×1011 grade and 1.0–3.0×1012 TFU/g for the 1×1012 grade.
What does the regulatory side look like?
In the EU, pasteurised A. muciniphila has a novel food authorisation (Regulation (EU) 2022/168) with defined conditions of use. In the US, supplements are labeled with structure/function wording and the DSHEA disclaimer; the manufacturer of AKM Lab-01 holds a self-affirmed GRAS conclusion from an independent expert panel, which is not an FDA approval.
Rules for the live form differ and can change, so confirm the position for each market yourself. We provide technical documents but cannot give legal advice.
Which form should you choose?
- Choose pasteurized if you need room-temperature storage, gummies, liquids, stick packs or a long shelf life.
- Consider live only if your concept depends on a living-culture positioning and you can support the cold-chain, packaging and stability burden.
- Either way, verify strain identity, the potency method and the certificate holder using our supplier checklist, and read what pasteurized Akkermansia is if you are new to the ingredient.
Our own ingredient, AKM Lab-01, is pasteurized; see the Akkermansia muciniphila ingredient page. We do not supply a live form.
FAQ
Frequently Asked Questions
Is pasteurized Akkermansia the same as dead bacteria?
It is heat-inactivated, so the cells cannot multiply, but they are intact and still carry heat-stable components such as the Amuc_1100 protein. “Inactivated” is the more precise term and is the one used on the manufacturer’s documents.
Why is CFU not used for pasteurized Akkermansia?
CFU counts living cells that can form colonies. A heat-inactivated powder is specified to contain almost none (below 10 CFU/g for AKM Lab-01), so potency is expressed as total cells in TFU/g instead.
Does pasteurized Akkermansia need refrigeration?
For AKM Lab-01 powder, the specification gives a 36-month shelf life in sealed, room-temperature storage, with no cold chain. Always follow the storage conditions on the batch documents.
Do you supply live Akkermansia?
No. Our Akkermansia ingredient is pasteurized AKM Lab-01. We can explain the differences, but we do not offer a live form.
Can I make claims for either form?
Claims depend on the market and on your own substantiation. In the US, structure/function wording with the DSHEA disclaimer is the usual route; in the EU, only authorised health claims may be used. Research on the species does not by itself support claims for a specific product.
