wann kefir am besten trinken — can a DNA test help?

The question of the best time to drink kefir lacks strong scientific evidence. Many sources suggest consuming kefir on an empty stomach in the morning to maximize probiotic survival through stomach acid, but this is based on practical reasoning rather than robust clinical trials. Others recommend evening intake due to kefir's tryptophan content, which may support sleep. A DNA test cannot provide personalized guidance on timing. Genetic variants such as those in LCT (lactose tolerance) or TAS2R38 (bitter taste) have no proven link to optimal kefir timing. MyBody-X DNA tests analyze certain SNPs but are not designed for this purpose. The evidence for using DNA tests to optimize kefir timing is best described as marketing or unclear. Regular kefir consumption offers general probiotic and prebiotic benefits regardless of timing. A practical safety note: avoid taking kefir simultaneously with antibiotics; space them apart. For individual health concerns, consult a healthcare professional.
