Lifeway Foods, Inc., a leading U.S. supplier of kefir and fermented probiotic products, has introduced Probiotic Smoothie + Collagen, a new functional beverage line made with kefir cultures. The line includes four flavors: Matcha Latte, Berry Blast, Tropical Fruit, and Plain. Each serving contains 5 grams of collagen and 25-30 billion CFUs (Colony Forming Units) from 12 live and active cultures. The product is lactose-free, catering to the growing consumer demand for lactose-free dairy options.
The Probiotic Smoothie + Collagen line is designed to support both gut and skin health through the gut-skin axis, a communication system that links the microbiome and skin. The product combines kefir’s natural nutrients, including Vitamins A, B, and D, with collagen to support skin hydration, elasticity, smoothness, and joint health. Kefir’s fermented properties also contribute to a healthy microbiome.
Julie Smolyansky, President and CEO of Lifeway Foods, highlighted kefir’s long history of use in skincare, tracing its roots to ancient practices such as Cleopatra’s baths in fermented milk. The growing popularity of fermented foods in skincare routines, fueled by viral trends and endorsements from experts, has increased interest in kefir’s benefits.
This marks the first probiotic collagen smoothie featuring kefir cultures on the market. Lifeway Foods, which began developing the product in 2021, is launching it as part of its New Year New You Campaign for 2025. The smoothies will begin shipping in December and will be available nationwide at select independent and specialty stores by the end of the year.
