Description
What is Lactobacillus gasseri?
Lactobacillus gasseri is a natural commensal bacterium found in the human vagina and intestinal tract, belonging to the genus Lactobacillus. It has attracted much attention for its excellent acid resistance, bile tolerance and strong adhesion ability. It can metabolize and produce antibacterial substances such as lactic acid, effectively inhibiting pathogenic bacteria including Escherichia coli, Staphylococcus aureus, Gardnerella vaginalis and Candida albicans.
As a multifunctional probiotic, Lactobacillus gasseri is supported by numerous clinical studies in the fields of weight management (reducing visceral fat), women’s vaginal health, intestinal function improvement and immune regulation. It is one of the core raw materials in products for women’s probiotics, metabolic health and intestinal health.

1. Weight Management and Visceral Fat Reduction
Strains Lactobacillus gasseri SBT2055 and BNR17 have been clinically proven in multiple human trials to significantly reduce visceral fat area, body weight and waist circumference.Consuming 10⁸ CFU/day of fermented milk containing SBT2055 for 12 weeks resulted in an average 8.5% reduction in visceral fat area.Supplementation with BNR17 at 10¹⁰ CFU/day for 12 weeks reduced visceral fat area by 21.6 cm² and significantly decreased waist circumference, making it a star strain for weight management formulations.
2. Maintenance of Women’s Vaginal Health
Lactobacillus gasseri strains CECT 30648 and VHProbi E09 produce lactic acid, effectively inhibiting Gardnerella vaginalis (inhibition rate 99.07%) and Candida albicans (inhibition rate 99.95%), preventing bacterial vaginosis and candidal infections.After oral administration of CECT 30648, the strain was detected in the vagina of 55.9% of participants, exhibiting broad-spectrum antibacterial activity against 10 urogenital pathogens.
3. Regulation of Intestinal Function and Constipation Relief
Lactobacillus gasseri strain 345A reduces abdominal pain and increases the frequency of complete spontaneous bowel movements in patients with functional constipation.Strain OLL2716 improves gastric emptying rate in patients with mild-to-moderate gastroparesis.It enhances digestive comfort by regulating intestinal peristalsis and balancing gut microbiota.
4. Immunomodulation and Anti-Inflammatory Effects
In a DSS-induced ulcerative colitis model, Lactobacillus gasseri strain FN136 at 1×10⁹ CFU/day significantly alleviated inflammation, increased regulatory T cells by 42.09%, and reduced pro-inflammatory cytokine levels, providing adjunctive benefits for inflammatory bowel disease.
5. Inhibition of Oral Pathogens
Selected strains of Lactobacillus gasseri inhibit oral cariogenic bacteria such as Streptococcus mutans and reduce plaque formation, offering benefits for dental caries prevention and oral health.
6. Lipid Regulation and Metabolic Improvement
Animal and preliminary clinical studies show that Lactobacillus gasseri can lower serum total cholesterol and LDL-cholesterol, improve insulin sensitivity, and support the management of metabolic syndrome.
1.Clear Strain
OriginLactobacillus gasseri is isolated from the vagina or intestinal tract of healthy humans, with well‑defined strain designations (such as SBT2055, BNR17, CECT 30648, VHProbi E09, 345A, OLL2716, FN136, etc.). Whole‑genome sequencing and 16S rRNA identification reports are available, with a clear genetic background.
2. Strong Acid and Bile Salt Tolerance
This strain exhibits excellent tolerance to gastric acid (pH 2.5) and bile (0.3%). Its survival rate in simulated gastrointestinal fluid can reach over 70%, allowing it to successfully pass through the gastrointestinal tract in a viable state and colonize the intestinal and vaginal mucosa.
3. Strong Adhesion and Colonization Ability
Lactobacillus gasseri possesses adhesion proteins on its surface, enabling firm binding to intestinal epithelial cells and vaginal epithelial cells. It competitively inhibits the colonization of pathogenic bacteria and maintains long‑term microecological balance.
Q1: What are the most well-known strains of Lactobacillus gasseri and their respective benefits?
A: SBT2055 (weight management, visceral fat reduction), BNR17 (abdominal fat reduction, waistline reduction), CECT 30648 (women’s vaginal health, broad-spectrum antibacterial activity), VHProbi E09 (inhibiting Gardnerella and Candida), 345A (relieving constipation), OLL2716 (improving gastric emptying), FN136 (anti-inflammatory, increasing Treg cells). We can provide detailed clinical documentation.
Q2: Can Lactobacillus gasseri really help with weight loss?
A: Yes. Clinical studies have confirmed that consuming fermented milk containing 10⁸ CFU of SBT2055 daily for 12 weeks resulted in an average 8.5% reduction in visceral fat area. Supplementation with 10¹⁰ CFU of BNR17 daily for 12 weeks reduced visceral fat area by 21.6 cm² and significantly decreased waist circumference. Its mechanisms include regulating gut microbiota, increasing fat oxidation, and reducing lipid absorption.
Q3: How does Lactobacillus gasseri benefit women’s vaginal health?
A: After oral administration of 10⁹ CFU/day of CECT 30648, the strain was detected in the vagina of 55.9% of participants, showing broad-spectrum antibacterial activity against 10 urogenital pathogens. VHProbi E09 inhibits Gardnerella vaginalis by 99.07% and Candida albicans by 99.95%, helping prevent bacterial vaginosis and candidal infections.
Q4: Who is Lactobacillus gasseri suitable for?
A: People managing their weight (especially those with abdominal obesity), women (for vaginal health maintenance), constipation sufferers, patients with inflammatory bowel disease, people with metabolic syndrome, and those seeking daily gut health support.
