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

Kefir is a fermented dairy product rich in probiotics that may support gut health. The best time to drink it depends on your goals: On an empty stomach in the morning, it can stimulate digestion and nutrient absorption. In the evening, its tryptophan content may promote relaxation and sleep. Avoid combining kefir with hot foods or drinks, as heat can kill beneficial bacteria. If you are sensitive to dairy, start with small amounts or try water kefir. Making kefir at home is simple: you need kefir grains (live cultures) or starter powder, fresh milk (or plant-based alternatives), and a clean glass jar. Ferment at room temperature for 24–48 hours, then strain and refrigerate. The grains can be reused. Evidence for specific timing is weak and based on anecdotal experience rather than robust studies. A gut microbiome test might indicate whether kefir is beneficial for you, but personal experimentation remains key.
