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

The best time to drink kefir is not firmly established by scientific evidence; most advice is based on general probiotic principles and anecdotal experience. Some research suggests taking probiotics on an empty stomach (e.g., first thing in the morning) may improve survival of beneficial bacteria through the acidic stomach environment. Others recommend kefir before bed due to its tryptophan content, which could support melatonin production, though the effect is modest. What you can do yourself: You can easily make kefir at home using kefir grains or starter cultures, which is cost-effective and ensures freshness. Ferment gently at room temperature for 12–24 hours, then refrigerate. Regular consumption (about 100–200 ml/day) may support gut health, but effects vary individually. Caveat: People with histamine intolerance or compromised immune systems should be cautious. The evidence for specific timing is weak; listen to your body and incorporate kefir consistently rather than obsessing over the clock.
