Summary

This study looks at whether drinking fruit kefir, a fermented probiotic beverage, changes certain chemicals in urine and saliva and affects feelings of well-being. Researchers will measure amino acids and stress-related biomarkers in 66 healthy adults who have never regularly consumed kefir. The goal is to understand how kefir might influence the body and mood, not to treat any disease.
