wann sollte man am besten kefir trinken — can a microbiome test help?

The optimal time to drink kefir is not well established by science. Some people tolerate it better on an empty stomach, others after meals. No robust studies show a superior timing. A microbiome test (e.g., from MyBody-X) can theoretically indicate your gut bacteria composition, but clinical validation for personalized dietary advice – especially timing of kefir – is lacking. Evidence is mechanistic/observational. Such tests may suggest broad trends but cannot provide reliable, actionable guidance. A single stool sample has limited predictive power. If you enjoy kefir, listen to your body: morning may stimulate digestion, evening may support gut rest. A test is not necessary. For intolerances or chronic issues, consult a doctor.
