What it is

Live cultures are beneficial microorganisms, often bacteria or yeasts, that are added to foods. They are typically found in fermented products and are known for their role in the fermentation process, which can enhance flavor and texture.

Why it's used

Live cultures are primarily added to foods to act as probiotics, which are thought to support gut health. They are commonly found in fermented dairy products like yogurt and kefir, as well as in other fermented foods such as sauerkraut, kimchi, and kombucha.

Health notes

Live cultures are generally recognized as safe (GRAS) by the FDA for use in foods. While often associated with health benefits like improved digestion, scientific evidence is still evolving, and effects can vary. International bodies like JECFA have evaluated some specific live cultures, but general statements about all live cultures are difficult to make. Some individuals may experience mild digestive upset when first consuming foods with live cultures.

Allergen info

Live cultures themselves are not one of the 9 FDA major allergens. However, the food product they are added to may contain allergens (e.g., dairy in yogurt). Not a major allergen.
