ist kefir am abend gesund — what can you do yourself?

Drinking kefir in the evening is generally safe and may offer benefits due to its probiotics, protein, and tryptophan content – an amino acid that serves as a precursor for melatonin and serotonin. However, the scientific evidence for a direct sleep-enhancing effect is weak: no large human trials have specifically examined evening kefir consumption. Observed effects are mostly based on animal or mechanistic data (e.g., gut–brain axis). Additionally, kefir can cause bloating or a mild insulin response in some individuals, which might disrupt sleep. What you can do yourself: try it and monitor your response. A small glass (about 150 ml) of plain, unsweetened kefir is a reasonable starting point. Combine it with good sleep hygiene (dim light, no heavy meals). Those with lactose intolerance or histamine sensitivity should be cautious. Overall, kefir is a healthy food but not a proven sleep aid. The evidence is mixed: mechanistically plausible but lacking clinical confirmation.
