wie oft sollte man kefir trinken — can a microbiome test help?

The optimal frequency for drinking kefir depends on individual tolerance, diet, and health goals. A common starting point is 100–200 ml (about one small glass) per day, allowing the gut to adapt to the probiotic cultures. If well tolerated, intake can be increased to 2–3 servings daily. A microbiome test (e.g., from MyBody-X) can provide a snapshot of your gut bacteria composition, potentially revealing low levels of beneficial strains like Bifidobacteria or Lactobacilli. However, the evidence for using such tests to derive personalized kefir dosing is still limited. Observational studies suggest that regular kefir consumption (daily over several weeks) can increase microbial diversity and reduce pro-inflammatory bacteria. Caveat: kefir is a food, not a drug. People with digestive disorders or compromised immunity should consult a doctor first. A microbiome test may offer general guidance but is not clinically validated for precise dosing recommendations. Evidence: practice (general dietary advice) and human-moderate (probiotic studies).
