Where BNR17 came from — and how it is made today
The Lactobacillus gasseri BNR17 strain was discovered through Korean breast milk research in the early 2000s. Korean microbiologists studying the gut microbiome of healthy infants isolated a distinctive probiotic strain from human breast milk samples. That strain was designated BNR17 and became the subject of a decade of clinical research by AceBiome Inc.
That discovery is now history. What happens in production today is different.
Once a microbial strain is isolated and characterised, it is preserved in cell banks — standard practice in biotechnology. From that cell bank, BNR17 is reproduced through controlled microbial fermentation in sterile bioreactors. The fermentation medium is plant-based. No breast milk is involved in any step of production. No breast milk has been used in the manufacturing of BNRThin Slim+ at any point.
What you receive in each stick is a powder containing live L. gasseri BNR17 organisms grown in a plant-based fermentation system, freeze-dried, and packed with a 3-phase desiccant to maintain viability. The breast milk origin is part of the scientific discovery story of this strain. It is not part of its current manufacturing process — in the same way that many microbial ingredients, enzymes, and vitamins are derived from original biological sources but are now produced entirely through industrial fermentation.
The Istihalah principle
Istihalah (الاستحالة) is a recognised principle in Islamic jurisprudence that addresses the concept of complete transformation. When a substance undergoes a fundamental change in its essential nature — through fermentation, chemical transformation, biological processes, or other means — its original origin no longer automatically determines its halal or haram status. The substance in its new form is evaluated as what it has become, not what it came from.
This principle is accepted by many Islamic scholars and applied widely in food science. Vinegar derived from wine is considered halal by the majority of scholars because the fermentation process completely transforms the alcohol — it is a different substance. Many enzymes used in food production are derived from microbial or animal sources but are considered permissible because the biological transformation is complete. Certain vitamins, flavourings, and fermentation-derived food ingredients are evaluated similarly.
The BNR17 in your sachet was cultivated in a plant-based fermentation medium under tightly controlled GMP conditions. The microbial cells that constitute BNR17 in your product have undergone the full biological process of fermentation, isolation, and drying. They are living probiotic organisms produced through controlled industrial microbiology — the same process used to produce many food-safe microbial ingredients found in products that carry halal certification.
Whether Istihalah applies in this specific context, and at what degree, is a matter for Islamic scholars and for your own religious authority to determine. We are not qualified to issue a religious ruling. We present the principle, the science, and the manufacturing facts so that you and your ustaz or mufti can make an informed judgement.
Full production transparency
AceBiome’s manufacturing facility in South Korea holds GMP certification — the same quality standard required for pharmaceutical production. Here is everything we know and can confirm about what is and is not in BNRThin Slim+:
- Fermentation medium: Plant-based. No animal-derived components in the growth medium.
- Pork & pork derivatives: None. Not used in production or as excipients.
- Alcohol: Not used in production or as a carrier.
- Gelatin: None. BNRThin Slim+ is a powder stick — not a capsule. No gelatin of any origin.
- Animal fats: None in the fermentation medium or formulation.
- Vegetarian suitability: Yes. Suitable for vegetarians.
- Dairy cross-contamination: The production facility also processes dairy-containing products. Trace dairy cross-contamination is possible. This is disclosed on the label. Consumers with dairy concerns — whether allergy or halal-related — should factor this into their decision.
We will not claim anything more than what we know and can confirm. The dairy cross-contact note is included because full transparency matters more to us than a cleaner-sounding answer.
Why we don’t have JAKIM certification yet
JAKIM (Jabatan Kemajuan Islam Malaysia) is Malaysia’s official halal certification authority. Obtaining JAKIM certification requires one of the following: an on-site audit of a Malaysia-located production facility, or certification by a JAKIM-recognised foreign certification body. JAKIM currently recognises a small number of foreign bodies, including KMF (Korea Muslim Federation) and IFANCA.
AceBiome’s production facility in South Korea is not currently certified by KMF or any other JAKIM-recognised foreign body. We are actively exploring this certification pathway. It involves AceBiome engaging directly with KMF for a facility audit and certification process in Korea — a process we are committed to pursuing.
We will not claim halal certification before it is obtained. Doing so would be dishonest, and it would be a disservice to the Muslim consumers who rely on certification as a genuine, audited assurance. This page will be updated the moment certification status changes.
Your decision. Your faith. Our respect.
We respect that the question of halal status is a personal and religious matter that deserves a thorough, honest answer — not a deflection or a claim we cannot back up. We have provided everything we know: the strain history, the manufacturing process, the Istihalah principle as it may apply, and the current certification status.
If you would like guidance specific to your situation, we encourage you to consult your local ustaz, mufti, or the religious authority you trust. You are welcome to share this page with them directly. We are also reachable at support@bnr17.my if you have questions we have not answered here.
This page will be updated when certification status changes. We thank you for asking — questions like yours help us be better.
