Water Kefir

Water kefir is a fermented beverage made from water, sugar, and a culture of bacteria and yeasts, often called kefir grains. The sugar is consumed during fermentation, resulting in a lightly sweet, effervescent drink. It is typically flavored with fruits or herbs.

Water kefir is primarily used as a probiotic beverage, offering a dairy-free alternative to traditional kefir. Manufacturers add it to drinks for its potential probiotic benefits and refreshing, slightly tart taste. It is commonly found in bottled drinks, teas, and other non-alcoholic beverages.

Water kefir is generally recognized as safe (GRAS) by the FDA for consumption. As a fermented food, it contains live microorganisms that may support gut health, though specific health benefits are still being researched. International bodies like JECFA have evaluated similar fermented products. Evidence for significant health impacts from typical consumption is mixed and requires more study.
