What it is

Lactobacillus delbrueckii subsp. bulgaricus is a type of bacteria commonly found in the digestive tracts of mammals. It is a key ingredient in the fermentation of milk to produce yogurt. This bacterium helps break down lactose, the sugar in milk, into lactic acid.

Why it's used

It is primarily used as a starter culture in the production of yogurt and other fermented dairy products. Its action creates the characteristic tangy flavor and firm texture of yogurt. It is also sometimes included in probiotic supplements.

Health notes

Lactobacillus delbrueckii subsp. bulgaricus is generally recognized as safe (GRAS) by the FDA for use in food. It is considered a probiotic, meaning it may provide health benefits when consumed. JECFA has evaluated it and set an acceptable daily intake. Research suggests probiotics may play a role in gut health, but more studies are needed to confirm specific benefits for this strain.

Allergen info

Not a major allergen. It is a bacterium and not derived from any of the nine FDA major allergens.
