Casei Subspecies Casei

Lactobacillus casei subspecies casei is a type of bacteria commonly found in the human gut and in fermented foods like cheese and yogurt. It is often used as a starter culture in the production of dairy products. This bacterium helps break down sugars into lactic acid, contributing to the tangy flavor of fermented foods.

This bacterium is primarily used as a probiotic, meaning it is intended to provide health benefits when consumed. It is added to foods like yogurt and fermented dairy drinks to support gut health. Manufacturers use it to enhance the nutritional profile and potentially improve the digestive qualities of their products.

Lactobacillus casei subspecies casei is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) for use in food. Probiotics containing this bacterium are widely studied for their potential to support digestive and immune health. International bodies like the European Food Safety Authority (EFSA) have also evaluated probiotics, and ongoing research continues to explore their specific benefits and mechanisms of action.
