Kefiran is a water-soluble polysaccharide produced by Lactobacillus kefiranofaciens found in kefir grains that functions as a postbiotic. It modulates gut microbiota composition and enhances immune function through interactions with intestinal epithelial cells and immune tissues.
Reported Benefits (Provisional)
Origin & History
Kefiran is a polysaccharide produced by kefir grains during the fermentation of milk. It is a key component of the unique texture and health benefits of kefir.
Research Narrative (Provisional)
Research highlights kefiran's role in gut health and immune modulation. Studies also suggest benefits in cholesterol reduction and antioxidant activity.
Preparation & Dosage
Dosage guidance is withheld because the publication gate has not recorded adequate support for this profile.
Nutritional Profile
- Rich in polysaccharides. - Contains bioactive compounds. - Low in calories.
Reported Mechanism (Provisional)
Kefiran acts as a prebiotic fiber that selectively promotes growth of beneficial bacteria like Bifidobacterium and Lactobacillus while inhibiting pathogenic species. It modulates immune responses by interacting with toll-like receptors and enhancing secretory IgA production in gut-associated lymphoid tissue. The polysaccharide also binds bile acids in the intestine, promoting their excretion and forcing cholesterol conversion to replace them.
Clinical Narrative (Provisional)
Human studies on isolated kefiran are limited, with most research conducted in animal models and cell cultures. A 12-week study in 94 adults showed kefir consumption (containing kefiran) reduced LDL cholesterol by 15% and improved inflammatory markers. Animal studies demonstrate immune-enhancing effects with 200-400mg/kg doses, but human equivalent dosing remains unclear. Current evidence suggests benefits but requires more robust clinical trials for definitive therapeutic claims.
