What it is

Thermophilus L is a strain of bacteria, specifically a type of lactic acid bacteria. It is often used in the production of fermented foods like yogurt and cheese. This bacterium helps break down sugars into lactic acid, contributing to the characteristic tangy flavor and texture of these products.

Why it's used

Thermophilus L is primarily used as a live culture in yogurt and other fermented dairy products. Its role is to ferment lactose (milk sugar) into lactic acid, which lowers the pH, thickens the product, and creates the desired tangy taste. It is also sometimes added to probiotic supplements.

Health notes

Thermophilus L is generally recognized as safe (GRAS) by the FDA for use in foods. As a probiotic, it is thought to contribute to a healthy gut microbiome, though research is ongoing. International bodies like JECFA have evaluated it, but did not set a specific numeric limit. Evidence regarding specific health benefits is still developing, and it is not considered a cure or cause of any disease.

Allergen info

Thermophilus L itself is not a major allergen. However, it is commonly found in dairy products like yogurt, which are derived from milk, a major allergen.
