Lactobacillus gasseri SBT2055

Lactobacillus gasseri SBT2055 is a probiotic strain that produces short-chain fatty acids and bacteriocins to modulate gut microbiota composition. This strain specifically targets visceral fat reduction through metabolic pathway regulation and enhances immune function via gut-associated lymphoid tissue stimulation.

Origin & History

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.

Historical & Cultural Context

Probiotics like Lactobacillus gasseri have been used in fermented foods for centuries, valued for their health benefits across various cultures.

Health Benefits

- Supports weight management by potentially reducing abdominal fat, with studies showing up to a 4% decrease in body fat percentage. - Enhances gut health by promoting beneficial bacteria growth, leading to improved digestion and reduced bloating. - Boosts immune function by enhancing the body's natural defenses against infections, reducing the frequency of colds. - Reduces inflammation by modulating immune responses, which can help manage chronic inflammatory conditions. - Improves metabolic health by regulating blood sugar levels, aiding in the prevention of type 2 diabetes. - Promotes mental clarity by influencing gut-brain communication, potentially improving focus and reducing brain fog. - Supports cardiovascular health by lowering cholesterol levels, contributing to a healthier heart.

How It Works

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.

Scientific Research

Research shows Lactobacillus gasseri SBT2055 may support weight management and gut health, with studies supporting its probiotic benefits.

Clinical Summary

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.

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.

Preparation & Dosage

Typically consumed in doses of 1-10 billion CFU per day. Consult a healthcare provider before use.

Synergy & Pairings

Weight management supplements, Bifidobacterium, Prebiotics, Gut microbiota, Immune support

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.
