wann kefir trinken — which blood markers matter?

When to drink kefir depends on individual goals and tolerance. Since kefir is fermented, it contains little lactose and is often tolerated even by those with lactose intolerance (rs4988235). For blood sugar control, kefir may be beneficial before or with meals, as probiotics and lactic acid can blunt glycemic response. Relevant blood markers include fasting glucose, HbA1c, triglycerides, and HDL cholesterol. In case of elevated triglycerides (e.g., due to APOA5 variants), kefir can be part of a balanced diet but not sole therapy. The SLC30A8 variant (zinc transporter, T2D risk) might be addressed by zinc-rich foods, but direct evidence for kefir is lacking. Note: MyBody-X tests are for adults; for children consult a pediatrician. Evidence: mixed practice and mechanistic, no strong clinical evidence for specific timing.
