wann soll man kefir trinken — what can you do yourself?

The question of when to drink kefir has no one-size-fits-all answer, as high-quality evidence is limited. Traditionally, kefir is consumed in the morning on an empty stomach to allow its probiotic cultures to reach the gut relatively undisturbed. Others prefer it before bed due to its tryptophan content, which may promote relaxation. What you can do yourself: You can easily make kefir at home using kefir grains (a symbiotic culture of lactic acid bacteria and yeasts) and milk. Fermentation takes about 24 hours at room temperature. Strain, reserve the grains for the next batch, and refrigerate the finished kefir. Important: milk quality and hygiene affect the final product. Health claims (e.g., improved digestion, immune modulation) are mostly based on mechanistic or animal studies; robust human trials are scarce. Individuals with sensitive stomachs or histamine intolerance may experience discomfort. Evidence: practice/unclear.
