Lifeway Foods is the largest U.S. producer and marketer of kefir, a cultured dairy product, as well as a recognized manufacturer of probiotic-based and natural "better for you" foods. The company produces drinkable kefir (its core product), cheese, cream, yogurt, and other dairy products under the Lifeway, Fresh Made, and GlenOaks Farms brand names, with most revenue derived from its own manufacturing facilities in Illinois, Wisconsin, and Pennsylvania, supplemented by co-packing arrangements. Lifeway distributes its products domestically through retail-direct sales to major grocers, independent distributors, and direct store delivery in the Chicago area, with international operations in Latin America, Europe, and the Middle East, generating revenue through sales of branded products and private-label goods to food retailers and distributors.
