Raw Cultured Water Kefir

Water kefir is a fermented beverage made from water, sugar, and kefir grains. The kefir grains are a symbiotic culture of bacteria and yeasts that consume the sugar and produce carbon dioxide, organic acids, and other compounds, giving the drink its characteristic effervescence and tangy flavor.

Manufacturers use water kefir as a probiotic ingredient and a source of natural carbonation in beverages. It is commonly found in sparkling probiotic drinks, kombucha alternatives, and other non-dairy fermented beverages.

Water kefir is generally recognized as safe (GRAS) by the FDA for use in food. As a fermented product, it contains live microorganisms that may contribute to gut health, though specific health benefits are still being researched. International bodies like JECFA have evaluated similar fermented products, but no specific evaluations for water kefir are widely cited. Evidence on the health effects of consuming fermented beverages like water kefir at typical levels is generally positive, but more research is needed to confirm specific benefits.
