Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Kefiran is a polysaccharide produced by certain strains of lactic acid bacteria in kefir grains. Its potential role in supporting or treating bacterial infections is primarily supported by preclinical (in vitro and animal) studies. Scientific investigations have shown that kefiran exhibits antimicrobial activity against several pathogenic bacteria, including Staphylococcus aureus, Escherichia coli, and Salmonella typhimurium. These effects are believed to stem from kefiran’s ability to disrupt bacterial cell membranes and inhibit microbial adhesion. Additionally, kefiran may modulate the host’s immune response, enhancing phagocytic activity and increasing certain cytokines, which could contribute to an improved defense against infections.

However, there is a lack of high-quality human clinical trials specifically assessing kefiran’s effectiveness for treating or preventing bacterial infections. Most of the available evidence is limited to laboratory and animal studies, and results cannot be directly extrapolated to humans without further research. As such, while there is scientific interest and some preliminary validation, the overall strength of evidence is low (rated 2 out of 5), and kefiran should not be considered a stand-alone or primary therapy for bacterial infections at this time. Further clinical studies are needed to confirm its efficacy and safety in humans.
