wieviel kefir am tag ist gesund — when to see a doctor?

A typical healthy daily amount of kefir is 100–200 ml (about a small glass). Kefir provides probiotics, vitamins, and minerals, but excessive intake may cause bloating or diarrhea. See a doctor if you experience persistent digestive issues after consuming kefir, have a weakened immune system, or suffer from a chronic condition. Also consult a physician before regular consumption if you take immunosuppressants or have had an organ transplant. Evidence for the exact amount is moderate – individual tolerance and kefir quality (pasteurized vs. raw) matter significantly.
