Kefir yogurt is rich in probiotics, which support gut health by promoting a balanced microbiome. Its high calcium content aids in bone strength, while proteins and B vitamins contribute to muscle repair and energy metabolism. Regular consumption may enhance digestion and immune function.

Common ingredients include pasteurized cow's milk and live kefir cultures such as Lactobacillus acidophilus, Lactobacillus rhamnosus, Lactobacillus lactis, and Streptococcus thermophilus. Some varieties may also contain chicory root fiber, fruit purees, and natural flavorings. Most brands avoid artificial additives.
