How are Kefir Darm and Haut related?

Kefir is a fermented dairy product rich in probiotic bacteria and yeasts. Its link to gut and skin health operates via the gut-skin axis: a balanced gut microbiome can lower systemic inflammation and strengthen the skin barrier. Kefir consumption may increase microbial diversity, potentially benefiting conditions like acne or eczema. Evidence is mostly observational or from small trials; large RCTs are lacking. Effects vary by individual baseline microbiome. MyBody-X can use microbiome and DNA tests to suggest whether kefir might be beneficial, but it is not a substitute for medical advice. Caution: kefir may cause issues in lactose-intolerant or histamine-sensitive individuals. Overall, kefir is a promising but not proven intervention for skin health.
