wie oft kefir trinken — which blood markers matter?

The optimal kefir intake depends on individual tolerance, gut health, and goals. A common recommendation is 100–200 ml (about one small glass) per day, with up to 500 ml if well tolerated. Key blood markers that may be affected by regular kefir consumption include: blood lipids (total cholesterol, LDL, HDL, triglycerides) – some studies show reductions in LDL and triglycerides; fasting glucose and HbA1c – kefir may improve insulin sensitivity; inflammatory markers like hs-CRP – probiotics can exert anti-inflammatory effects; homocysteine – due to B-vitamin content (B2, B12, folate). Note: effects are modest and vary between individuals. Kefir is often better tolerated than milk in lactose intolerance, but caution is needed in histamine-sensitive individuals. Evidence comes mainly from observational studies and small RCTs; large long-term trials are lacking. Therefore, consider kefir as part of a balanced diet, not a magic bullet.
