wann sollte man am besten kefir trinken — which blood markers matter?

The question of the best time to drink kefir and which blood markers matter is not directly supported by the provided contexts. Generally, kefir is often recommended in the morning on an empty stomach or before bed due to its probiotic content, potentially influencing gut health. Blood markers that might be affected include lipids (cholesterol, triglycerides), inflammatory markers (CRP), and glucose. However, the given knowledge context contains no specific studies or guidelines on kefir. Therefore, the evidence level is 'unclear'. Consumers should be cautious about such claims and consult a healthcare professional for personalized advice.
