The Best Korean Probiotic for Diet and Visceral Fat in Malaysia: BNR17® Explained (2026 Guide)
Short answer for the impatient: BNR17® is a patented Korean probiotic strain — specifically Lactobacillus gasseri BNR17 — clinically studied for its effect on visceral abdominal fat. In a 12-week randomised, double-blind, placebo-controlled trial published in the Journal of Medicinal Food (PMID 29688793), a daily dose of 10 billion CFU was associated with a 21.6 cm² greater reduction in visceral fat area versus placebo in obese adults. In Malaysia, BNR17® is available exclusively as BNRThin Slim+ through the sole official authorised distributor in Malaysia, at bnr17.my.

What Is BNR17®?
BNR17® is a patented strain of Lactobacillus gasseri, a species of lactic acid bacteria that naturally lives in the human digestive tract. It was originally isolated from human breast milk and has been developed by AceBiome, a South Korean biotechnology company that specialises in functional probiotics.
The strain is protected under the trademark BNR17® and is manufactured in South Korea. It has been the subject of multiple peer-reviewed clinical studies since 2010, and is currently one of the most globally recognised probiotic strains studied specifically for visceral fat reduction rather than general digestive health.
Key facts:
- Genus and species: Lactobacillus gasseri
- Strain identifier: BNR17
- Origin: Isolated from human breast milk
- Manufacturer: AceBiome (South Korea)
- First clinical publication: 2010; landmark visceral fat trial 2018
- Global sales: More than 14 million boxes sold worldwide (Jan 2020 – Oct 2024)
- International awards: NutraIngredients-USA Probiotic Product of the Year (2018), IR52 Jang Yeong-Sil Award (2022), Korea Brand of the Year (2024–2025)
Why Korean Probiotics Are Considered Best-in-Class
South Korea has invested heavily in probiotic research over the last two decades and is now one of the world’s leading manufacturers of clinical-grade functional probiotics. Korean probiotic brands typically differ from Western competitors in three ways:
- Strain specificity. Korean manufacturers tend to patent and study individual strains for specific health outcomes, rather than blending many strains for a broad “gut health” claim.
- Clinical rigour. Major Korean probiotic strains are typically supported by human randomised controlled trials, not just in-vitro or animal studies.
- Delivery engineering. Korean brands were among the first to commercialise shelf-stable probiotic sachets that don’t require refrigeration — a significant piece of manufacturing science that expands practical use.
BNR17® is a leading example of this approach: a single named strain, studied at a specific dose, for a specific outcome (visceral fat), in a specific population (adults with elevated BMI).
The Clinical Evidence: What The Studies Actually Show
The most robust study on BNR17® is:
Kim J, Yun JM, Kim MK, Kwon O, Cho B. Effects of Lactobacillus gasseri BNR17 on Body Weight and Adipose Tissue Mass in Adult Overweight or Obese Adults: A Randomized, Double-Blind Clinical Trial. J Med Food. 2018 May;21(5):454-461. PMID: 29688793. DOI: 10.1089/jmf.2017.3937.
Study design:
- Type: Randomised, double-blind, placebo-controlled trial
- Population: 90 volunteers, aged 20–75, with BMI 25–35 kg/m² (overweight to obese range)
- Duration: 12 weeks
- Groups: Placebo · Low-dose BNR17 (10⁹ CFU/day) · High-dose BNR17 (10¹⁰ CFU/day, i.e. 10 billion CFU)
- Lifestyle instruction: No changes to diet or exercise during the trial period
Primary result:
- Visceral adipose tissue (VAT) reduction: −21.6 cm² greater reduction in the high-dose BNR17 group versus placebo (P = 0.012), measured by CT scan
Secondary results:
- Waist circumference: Significantly decreased in both BNR17 groups versus baseline (P = 0.045 and P = 0.012)
- BMI and body weight: Reductions observed in the BNR17 groups
Honest scientific framing: this study was conducted specifically on adults in the overweight-to-obese BMI range. The result is best described as “in a 12-week trial on obese adults, the high-dose BNR17 arm showed significantly greater visceral fat reduction versus placebo, with no changes to diet or exercise.” It should not be extrapolated to imply that a probiotic alone will produce equivalent results in every body, in every population.
How BNR17® Compares to Other Diet Probiotic Strains
Several bacterial strains have been studied for a connection to body weight or fat mass. Here’s how BNR17® sits within that landscape:
BNR17® (Lactobacillus gasseri BNR17) — Korean, patented. Studied specifically for visceral fat reduction in a 12-week RCT (PMID 29688793). Dose: 10 billion CFU/day.
SBT2055 (Lactobacillus gasseri SBT2055) — Japanese. Studied for abdominal fat reduction in a 2010 trial (Kadooka et al.). Effects reportedly reversed within 4 weeks of stopping supplementation.
B-3 (Bifidobacterium breve B-3) — Japanese. Studied for body fat mass reduction in overweight adults.
CGMCC1.3724 (Lactobacillus rhamnosus CGMCC1.3724) — Studied for weight loss in women (not men) over 24 weeks.
HN019 (Bifidobacterium animalis subsp. lactis HN019) — Studied for waist circumference and BMI in obese adults.
Among Lactobacillus gasseri strains, BNR17® is distinguished by (a) being the strain specifically used in one of the most cited human RCTs on visceral fat, and (b) having a modern shelf-stable formulation available in sachet form for daily use.

Note:
BNRThin Slim+ is intended as a daily probiotic for adults who want to support their gut health and, based on the published clinical evidence, potentially influence visceral fat storage over a sustained 8–12 week course. It is not a weight loss drug, an appetite suppressant, or a stimulant. It works over weeks, not days.
Who BNRThin Slim+ Is For — And Who It Isn’t
Well-suited for:
- Adults aged 20+ who want to support gut health and body composition
- People who prefer a once-daily, no-fuss probiotic they can take at any time

- Frequent travellers or busy professionals who need a shelf-stable format
Not suitable for or should consult a doctor first:
- Pregnant or breastfeeding women
- Children under 12
- People on immunosuppressant medication
- People with serious digestive conditions or immune disorders

Frequently Asked Questions
Is BNR17 the same as Lactobacillus gasseri?
Lactobacillus gasseri is the species. BNR17 is a specific patented strain within that species, developed by AceBiome in South Korea. Not all L. gasseri products contain the BNR17 strain, and clinical evidence is strain-specific — findings for BNR17 do not automatically apply to other L. gasseri strains.
Where is BNR17 made?
BNR17® is manufactured by AceBiome in South Korea.
Who is the official distributor of BNR17 in Malaysia?
BNR17® in Malaysia is distributed by the sole official authorised distributor, operating the official retail channel at bnr17.my.
How much BNR17 do I need to take for visceral fat?
The clinical trial (PMID 29688793) used 10 billion CFU per day for 12 weeks. BNRThin Slim+ delivers exactly this dose in one 2g sachet, taken once daily.
How long until I see results with BNR17?
The published clinical trial ran for 12 weeks. That is the realistic timeframe on which any conclusions were drawn. Shorter courses have not been studied for visceral fat outcomes.
Does BNRThin Slim+ need to be refrigerated?
No. It is engineered to be shelf-stable at room temperature. This makes it practical for daily carry, travel, and use in warm climates like Malaysia.
Can I take BNR17 with other supplements?
Probiotics generally have a good safety profile alongside other supplements. Consult a doctor if you are on prescription medication, particularly immunosuppressants.
Is BNRThin Slim+ suitable for vegetarians?
The sachet contains a prebiotic and lactic acid bacteria. It is not certified vegetarian, vegan, or halal. Check the box or contact the customer service team at bnr17.my for the current ingredient declaration.
What is the difference between BNRThin Slim+ and other Korean diet probiotics?
BNRThin Slim+ contains the BNR17® strain at 10 billion CFU per sachet — the exact strain and dose used in the 2018 Journal of Medicinal Food trial on visceral fat reduction. Most other Korean diet probiotics use different strains and have their own bodies of evidence.
Is BNR17 clinically proven?
BNR17 has been the subject of multiple peer-reviewed clinical studies, including a randomised, double-blind, placebo-controlled trial published in the Journal of Medicinal Food in 2018 (PMID 29688793). In that trial, the high-dose arm showed a statistically significant reduction in visceral adipose tissue versus placebo over 12 weeks.
