Probiotic Cultures: L

Probiotic cultures are live microorganisms, often bacteria or yeasts, that are intended to have health benefits when consumed. They are naturally found in the human gut and can also be found in fermented foods. For commercial use, specific strains are grown in controlled environments and then added to food products.

Manufacturers add probiotic cultures to foods to enhance their potential health benefits, particularly for gut health. They are most commonly found in fermented dairy products like yogurt and kefir, but also appear in some juices, cereals, and dietary supplements.

Probiotic cultures are generally recognized as safe (GRAS) by the FDA for use in foods. While many people consume them for potential benefits to gut health, scientific evidence is still developing and can vary by specific strain. International bodies like JECFA have evaluated some probiotics. Some research suggests potential benefits for digestive health, but more high-quality studies are needed to confirm effects for specific strains and conditions.
