Kefir is a fermented milk drink rich in probiotic bacteria and yeasts. Typical symptoms that may improve with kefir include bloating, irregular bowel movements, mild digestive discomfort, and a general sense of sluggish digestion. The lactic acid bacteria can support gut flora balance and promote digestion. However, some individuals may initially experience increased gas or mild cramping as the gut adjusts. Important: kefir is not a medication and cannot cure serious gut conditions like IBS or inflammatory bowel disease. Persistent or severe symptoms require medical evaluation. The evidence for kefir's effect on specific symptoms is moderate, based on general gut health studies rather than clinical diagnoses. A MyBody-X microbiome test can analyze your individual gut bacteria but cannot diagnose conditions.
