Introducing Korea's top-selling product, BNR17 Diet Probiotics BNRThin PRO! This supplement features Lactobacillus gasseri BNR17™, the first lactobacillus recognised by the Korean Ministry of Food and Drug for its ability to reduce body fat. It provides dual benefits: reducing body fat and improving intestinal health, earning high praise from consumers in Korea.

Each capsule guarantees 10 billion bacteria until the end of its shelf life and contains a synbiotics formula with prebiotics to promote the growth and activity of Lactobacillus in the intestines.

The capsules are made of Vegetable HPMC (Hydroxypropyl Methylcellulose), making them suitable for vegetarians.

A study of 210 people with central obesity (excess belly fat) showed that taking Lactobacillus gasseri BNR17™ daily resulted in an 8.5% belly fat reduction over 12 weeks.

Lactobacillus gasseri BNR17™ is a probiotic strain originally isolated from human breast milk and developed over nearly 20 years by Bioneer and AceBiome. It supports both gut health and body fat reduction, with research featured in top SCI-rated reports globally confirming its fat-reducing effects through various tests.

Unlike other supplements, BNR17 Diet Probiotics BNRThin PRO contains live and fresh cultures. The capsules are stored in a Patented Desiccant Vial to protect them from moisture without silica gel and are delivered via cold chain services to ensure their effectiveness.

This rare lactic acid bacteria grows slowly and is produced in small quantities under strict processes and management. After 20 years of research, Bioneer and AceBiome identified it among the ingredients in Korean mother’s breast milk and applied for a patent after confirming its anti-obesity functionality.

By consuming BNR17 Diet Probiotics BNRThin Pro, it helps to:

  • Prohibit carbohydrate absorption into your body
  • Excess carbohydrates are excreted from the body, resulting in LESS WEIGHT GAIN


  • Take one capsule per day with cold water consistently for a month (Recommended to take for 3 months or longer for best results).
  • You may take 1-2 capsules per day but effects may vary among individuals with the consumption intake.
  • It is recommended NOT TO take it with hot water or acidic beverage.
  • Close the lid tightly after use and do not reuse the container for other purposes
  • In case of underlying disease, allergies reaction or taking other medicine, please consult a specialist before consumption or purchase.
  • Store in refrigerator (0~10°C). If unopened, product can be stored at room temperature for up to 7 days.
  • Effectiveness of product is not affected even if the ice gel melts.

For best results, take at the same time each day (e.g., before bed, after meals). If you have a weak digestive system, take after meals.

Note: However, if the individual’s digestive system is weak, it is recommended to take only after his/her meals.

1. For ladies who are Pregnant, Breastfeeding or experiencing Pre-conception: There are no reports of any special side effects on these cases, but it is recommended that the individual should only purchase or consume after consultation with a specialist because it may differ among individuals during this sensitive period.

2. Which probiotics should I consume if I am 16 years old: You can consume either BNR17 or BNRKIDS. However, if you would like to focus on weight loss, we would recommend BNR17 BNRThin Pro. Please do not consume both probiotics concurrently.

3. For individuals with diabetes or high blood pressure: It is recommended that the individual should only purchase or consume after consultation with a specialist

4. For vegetarians' consumption: BNR17 contains milk so they are NOT vegan friendly. As there are different types of vegetarians, it would be best for individuals to check the ingredient list or with a doctor before purchasing or consumption.

5. When taking this product, please avoid taking antibiotics and foods that are generally unhealthy, such as alcohol and tobacco.

6. As BNRThin Pro is a lactobacillus product, there may be occurring cases of diarrhoea, constipation, abdominal swelling, etc. This is a symptom of a temporary change in the intestinal environment and it would revert back to normal after two to three weeks.

7. For individuals who would like to consume the probiotics during their usual timing while travelling: An experiment on the product's stability at room temperature or above has been conducted and the amount of live probiotics were still stable at about 30℃ for 7 days.

After 7 days, they were still stable at 5℃ of the changed condition for another 7 days. As such, customers may travel with BNRThin+ for a short time (store at room temperature for 7 days) but they should keep it refrigerated again when possible.

8. For individuals who consume BNR17 more than 3 months:
Individuals who take BNR17 for more than 3 months can have continuous weight loss. However, the amount of weight loss may vary among individuals.

9. Is it okay to consume other probiotics together with this?
There are no reports of any special side effects on these cases. However, we are unsure of the ingredients component in the other probiotics and if they will react with that of BNR17. We strongly recommend individuals to consult their doctors before purchase or usage.

10. Will my weight bounce back if I don’t continue?
As each individuals' body system may vary, it may differ. There are no reports of such cases. It is recommended to consume probiotics in the long run along with an active lifestyle to ensure good gut health!

11. What is the difference between BNRThin+ and the existing BNR17 BNRThin Pro?
• Form: BNRThin Pro is in capsule form, but BNRThin+ is in powder form.
• Flavour: BNRThin Pro has no flavour. On the other hand, BNRThin+ has a green apple flavour.
• Ingredients: While both of them have BNR17 probiotic as its main ingredient, they have different functions. Specifically, BNRThin+ has vitamin D for bone health and zinc for immunity.
