pre_text: PRODUCTS Our primary product is drinkable kefir, a cultured dairy product. Lifeway Kefir is tart and tangy, high in protein, calcium and vitamin D. Thanks to our exclusive blend of kefir cultures, each cup of kefir contains 12 live and active cultures and 15 to 20 billion beneficial CFU (Colony Forming Units) at the time of manufacture. We manufacture (directly or through co-packers) our products under our own brand, as well as under private labels on behalf of certain customers.
