Lactobacillus gasseri SBT2055 is a probiotic strain known for its potential weight management and gut health benefits. It is commonly found in the human gut and some fermented foods.
“Probiotics like Lactobacillus gasseri have been used in fermented foods for centuries, valued for their health benefits across various cultures.”Traditional Medicine
Scientific Research
Research shows Lactobacillus gasseri SBT2055 may support weight management and gut health, with studies supporting its probiotic benefits.
Preparation & Dosage

Traditional preparation
Typically consumed in doses of 1-10 billion CFU per day. Consult a healthcare provider before use.
Nutritional Profile
- Available in probiotic supplements and some dairy products. - Contains live bacteria beneficial for weight management and gut health. - Often combined with other probiotics for enhanced effects.
How It Works
Mechanism of Action
L. gasseri SBT2055 produces butyrate and acetate short-chain fatty acids that activate AMPK pathways and inhibit fatty acid synthesis in adipocytes. The strain modulates inflammatory cytokine production by enhancing IL-10 and reducing TNF-α through TLR2 receptor interactions. It also increases secretory IgA production and strengthens intestinal barrier function by upregulating tight junction proteins claudin-1 and occludin.
Clinical Evidence
A 12-week randomized controlled trial with 210 participants showed L. gasseri SBT2055 supplementation reduced visceral fat area by 4.6% and body weight by 1.4kg compared to placebo. Additional studies demonstrated improved inflammatory markers with decreased C-reactive protein levels by 25% in 87 adults over 8 weeks. The evidence is moderate-quality with most studies conducted in Japanese populations, limiting generalizability to other ethnic groups.
Safety & Interactions
L. gasseri SBT2055 is generally well-tolerated with mild digestive symptoms like bloating or gas occurring in less than 5% of users during the first week. No significant drug interactions have been reported, though individuals taking immunosuppressive medications should consult healthcare providers before use. The strain appears safe during pregnancy and breastfeeding based on limited data, but pregnant women should seek medical advice. People with severe immunocompromised conditions should avoid probiotic supplementation without medical supervision.

Frequently Asked Questions
How much weight can I lose with Lactobacillus gasseri SBT2055?
Clinical studies show participants lost an average of 1.4kg (3.1 pounds) over 12 weeks with daily supplementation. Visceral fat area decreased by 4.6%, with the most significant changes occurring in abdominal fat rather than overall body weight.
What is the recommended dosage of Lactobacillus gasseri SBT2055?
The clinically effective dose is 10^8 to 10^10 CFU (colony forming units) taken daily with meals. Most successful weight management studies used 10^10 CFU daily for 12 weeks, though benefits may be seen as early as 4-6 weeks.
Can Lactobacillus gasseri SBT2055 cause side effects?
Side effects are rare and mild, typically including temporary digestive discomfort, bloating, or gas during the first 3-7 days of use. These symptoms usually resolve as the gut microbiome adjusts to the probiotic supplementation.
How long does it take to see results from Lactobacillus gasseri SBT2055?
Initial digestive improvements may occur within 1-2 weeks, while weight management benefits typically become noticeable after 4-6 weeks of consistent use. Maximum fat reduction effects are observed after 12 weeks of daily supplementation according to clinical trials.
Should Lactobacillus gasseri SBT2055 be taken with food?
Yes, taking this probiotic with meals improves bacterial survival through stomach acid and enhances colonization in the intestines. Studies showing weight loss benefits used dosing with breakfast or the largest meal of the day for optimal absorption.
Is Lactobacillus gasseri SBT2055 safe during pregnancy and breastfeeding?
Lactobacillus gasseri SBT2055 is generally recognized as safe for most people, including pregnant and breastfeeding women, as it is a non-pathogenic strain. However, pregnant or nursing women should consult their healthcare provider before starting any new supplement to ensure it aligns with their individual health status. Most clinical studies on this strain have not reported adverse effects during pregnancy, but individualized medical advice is recommended.
Does Lactobacillus gasseri SBT2055 interact with common medications?
Lactobacillus gasseri SBT2055 does not typically interact with common medications, as probiotics generally work in the digestive tract and do not affect drug metabolism. However, if you are taking immunosuppressant medications or have a severely compromised immune system, you should consult your doctor before supplementing. Antibiotics may reduce probiotic efficacy, so spacing intake by 2–3 hours is often recommended.
What does clinical research show about Lactobacillus gasseri SBT2055's effectiveness?
Clinical studies on Lactobacillus gasseri SBT2055 demonstrate measurable benefits, including reductions in abdominal fat (up to 4% decrease in body fat percentage) and improvements in gut health markers. Research indicates the strain effectively enhances immune function and reduces inflammatory markers in the body. Most published studies used doses of 1×10^10 CFU or higher, with effects typically observed after 8–12 weeks of consistent supplementation.
