What it is

Kefir cultures are a symbiotic matrix of bacteria and yeasts, often referred to as kefir grains. These microorganisms ferment milk, producing kefir, a tangy, probiotic-rich beverage.

Why it's used

Manufacturers use kefir cultures to create fermented dairy products like kefir and yogurt, imparting a characteristic sour flavor and creamy texture. They are also used to add probiotic benefits to various foods and beverages.

Health notes

Kefir cultures are generally recognized as safe (GRAS) by the FDA for use in foods. The probiotics found in kefir are associated with potential benefits for gut health, though research is ongoing. International bodies like JECFA have evaluated probiotics, but specific regulatory limits for kefir cultures are not typically set. Evidence on specific health outcomes is still developing.

Allergen info

Kefir cultures themselves are not a major allergen. However, kefir is typically made from cow's milk, which is a major allergen. Gluten is not present unless added.
