Lactobacillus sakei Probio-65
Lactobacillus sakei Probio-65 is a probiotic strain that produces antimicrobial compounds including sakacin and organic acids to support respiratory and immune health. It modulates cytokine production and enhances antibody synthesis through interaction with intestinal immune cells.

Origin & History
Lactobacillus sakei Probio-65 is a probiotic strain commonly found in fermented foods like kimchi. It is known for its role in supporting respiratory health and enhancing the immune system.
Historical & Cultural Context
Lactobacillus sakei is traditionally used in the fermentation of kimchi, a staple in Korean cuisine. It has been valued for its health benefits in respiratory and immune health.
Health Benefits
- Supports respiratory health by reducing inflammation, as shown in a study where it decreased cytokine levels by 30%. This helps prevent infections and promotes easier breathing. - Enhances immune function by stimulating the production of antibodies, which helps the body fend off pathogens more effectively. - Aids in gut health by promoting the growth of beneficial bacteria, improving digestion and nutrient absorption. - Reduces the risk of sinus infections by inhibiting harmful bacteria, leading to fewer sinus-related issues. - Improves skin health by modulating the skin's microbiome, reducing acne and other skin conditions. - Supports weight management by influencing gut hormones that regulate appetite, helping to control cravings. - Enhances mental well-being by producing neurotransmitters like serotonin, which can improve mood and reduce anxiety.
How It Works
Lactobacillus sakei Probio-65 produces sakacin, a bacteriocin that inhibits pathogenic bacteria by disrupting cell membrane integrity. The strain stimulates Toll-like receptors on intestinal epithelial cells, activating NF-κB and MAPK signaling pathways that regulate cytokine production. It also enhances IgA antibody synthesis by promoting B-cell differentiation through interaction with Peyer's patches in the gut-associated lymphoid tissue.
Scientific Research
Research indicates Lactobacillus sakei Probio-65 can support respiratory health and enhance the immune system. Studies also suggest its potential in reducing allergy symptoms.
Clinical Summary
Clinical evidence for Lactobacillus sakei Probio-65 is limited but shows promise in respiratory health applications. One study demonstrated a 30% reduction in inflammatory cytokine levels, suggesting anti-inflammatory activity. Research indicates enhanced antibody production, though specific sample sizes and study durations require further documentation. More rigorous randomized controlled trials are needed to establish definitive therapeutic benefits and optimal dosing protocols.
Nutritional Profile

Safety & Interactions
Lactobacillus sakei Probio-65 is generally recognized as safe for healthy adults, with minimal reported adverse effects. Mild gastrointestinal symptoms like bloating or gas may occur during initial supplementation. Immunocompromised individuals should consult healthcare providers before use due to potential risk of opportunistic infections. No significant drug interactions have been reported, though concurrent antibiotic use may reduce probiotic viability.
