Summary

This kefir product contains beneficial ingredients such as pasteurized milk, nonfat milk, and a variety of probiotic cultures that support gut health. However, the presence of added cane sugar and natural flavors contributes to its ultra-processed nature, which limits its overall health score. Despite the inclusion of vitamin D3 and live cultures, the processing level and added sugar prevent it from achieving a higher rating.
