wann sollte man am besten kefir trinken — what are common causes?

The question of the best time to drink kefir is not supported by strong clinical evidence but relies on experiential knowledge and physiological reasoning. Many people drink kefir on an empty stomach in the morning to allow probiotic cultures to reach the gut with minimal interference from stomach acid and food. Stomach acid concentration may be lower after a meal, which could improve bacterial survival, but evidence is weak and varies by kefir strain and individual acid production. Others prefer kefir before bed because it contains tryptophan, which may support melatonin production – again, this is largely anecdotal. Common reasons for consuming kefir include improving gut health, alleviating digestive issues, boosting immunity, and occasionally weight management. These effects are partially supported by studies on fermented dairy products, but not specifically for kefir. Caution: individuals with lactose intolerance or histamine sensitivity may experience discomfort. Overall, the evidence is best classified as 'practice' – no robust RCTs exist on optimal timing.
