ist kefir am abend gesund — what are common causes?

Whether kefir is healthy in the evening depends on individual factors. Kefir contains probiotics that may support gut health and tryptophan, a melatonin precursor, which could aid sleep. However, its acidity may trigger heartburn or digestive issues in sensitive individuals. Additionally, kefir contains trace alcohol from fermentation, which might disrupt sleep in some people. Evidence on evening kefir specifically is limited; most data come from general probiotic research. For most people, kefir in the evening is safe, but caution is advised for those with reflux or lactose intolerance (rs4988235). A small serving (150 ml) 1–2 hours before bed is a reasonable approach. Evidence: human-moderate (observational studies, no specific evening trial).
