wie oft sollte man kefir trinken — what are common causes?

Kefir is a fermented milk product rich in probiotics. How often you should drink it depends on your tolerance, gut health, and diet. A common recommendation is 100–200 ml daily to support gut microbiota. Beginners or sensitive individuals may start with 50 ml and gradually increase to avoid bloating or diarrhea. Common causes of adverse reactions include lactose intolerance (kefir has less lactose than milk but is not lactose-free), histamine sensitivity, or overconsumption. Evidence for health benefits is mostly mechanistic and observational; robust clinical trials are limited. Caveat: Immunocompromised individuals or those with severe GI conditions should consult a doctor before regular intake.
