wann soll man kefir trinken — what does this mean exactly?

The question of the optimal time to drink kefir is not scientifically settled. Kefir is a fermented milk product rich in probiotics, vitamins, and minerals. From a nutritional perspective, there is no evidence that any specific time of day is superior. Some people prefer kefir in the morning on an empty stomach to support gut flora, while others drink it in the evening due to its calming effect from tryptophan precursors. However, no controlled studies confirm a best timing. Individual factors such as tolerance, medication use (e.g., antibiotics), or existing gastrointestinal conditions may influence the choice. For sensitive stomachs, kefir on an empty stomach may cause bloating; consuming it with a meal is then better. Claims that kefir must be drunk in the morning are marketing-driven and not evidence-based. Bottom line: Drink kefir when it suits you best. Focus on quality (low sugar, no additives) and start with small amounts if you have sensitivities.
