Efficacy and Safety of Kefir Whey Postbiotics

Research staff conduct screening tests only on applicants who provide written consent and select research subjects who meet the selection criteria. Study subjects will visit for the first time within 4 weeks from the screening visit to reexamine the suitability of the study subject selection/exclusion criteria and then be enrolled in the human application test. The participants will be randomly assigned to the kefir lactic acid bacteria-derived whey post-biotics group and the placebo group for the first time. Complete the baseline evaluation by the date of visit. Afterwards, the participants will consume whey postbiotics derived from kefir lactic acid bacteria and a placebo product twice a day, 3g per time, for 12 weeks, and visit the institution a total of four times to perform a grip strength test, DXA, etc. This survey will be conducted at Hanyang University Hospital. Research staff may conduct follow-up observations of study subjects as needed after final consumption of the kefir lactic acid bacteria-derived whey postbiotic group and placebo products or after early termination.
