Lactobacillus gasseri BNR17

Lactobacillus gasseri BNR17 is a clinically studied probiotic strain that produces bacteriocins and short-chain fatty acids to support weight management and metabolic health. This strain specifically targets visceral fat reduction and enhances gut barrier function through modulation of the gut microbiome.

Origin & History

Lactobacillus gasseri BNR17 is a probiotic strain isolated from human breast milk. It is cultivated under strict conditions to maintain its probiotic properties. This strain is renowned for its potential weight management benefits.

Historical & Cultural Context

Lactobacillus gasseri BNR17 has been extensively studied in Korea and Japan for its potential in weight management and gut health.

Health Benefits

- Supports weight management by reducing body fat, enhancing metabolic health. - Promotes healthy gut flora and digestion, improving nutrient absorption. - May reduce waist circumference by 2% in 12 weeks, aiding in body shaping. - Enhances immune function by boosting antibody production, reducing illness risk. - Reduces inflammation by modulating cytokine levels, promoting overall wellness. - Improves cholesterol levels by breaking down fats, supporting heart health. - Boosts mood by producing serotonin, enhancing mental well-being.

How It Works

Lactobacillus gasseri BNR17 produces bacteriocins that inhibit pathogenic bacteria while generating butyrate and acetate short-chain fatty acids that strengthen intestinal barrier integrity. The strain modulates the gut-brain axis by influencing GLP-1 secretion and leptin sensitivity, which helps regulate appetite and fat metabolism. It also enhances bile acid metabolism, promoting lipid breakdown and reducing visceral fat accumulation.

Scientific Research

Several randomized controlled trials have demonstrated its efficacy in weight management and gut health. Emerging studies suggest benefits for metabolic health.

Clinical Summary

Clinical trials with Lactobacillus gasseri BNR17 have shown significant weight management benefits in controlled studies. A 12-week randomized trial demonstrated a 2% reduction in waist circumference among participants taking the probiotic supplement. Additional studies indicate improvements in body fat percentage and metabolic markers, though most research involves relatively small sample sizes of 50-100 participants. The evidence suggests consistent but modest effects on weight management when combined with standard dietary approaches.

Nutritional Profile

- Produces lactic acid, aiding in gut health. - Contains enzymes that facilitate digestion. - Contributes to the production of beneficial short-chain fatty acids.

Preparation & Dosage

Typically taken in doses of 1-10 billion CFUs per day. Available in capsule or powder form. Consult a healthcare provider before use.

Synergy & Pairings

Green Tea Extract, Fiber, Chromium

Safety & Interactions

Lactobacillus gasseri BNR17 is generally well-tolerated with minimal side effects, though some individuals may experience mild digestive symptoms like bloating or gas during initial use. No significant drug interactions have been reported, but individuals taking immunosuppressive medications should consult healthcare providers before use. The strain appears safe for healthy adults, but pregnant and breastfeeding women should seek medical advice before supplementation. People with severe immune compromise or active gastrointestinal infections should avoid probiotic supplementation.
