What are probiotics?

Probiotics refer to live beneficial bacteria that support gut health. They are microorganisms that, when consumed in adequate amounts, can confer health benefits to the host, particularly in maintaining a balanced gut microbiota. Probiotics can help improve digestion, enhance immune function, and may even provide relief from certain gastrointestinal conditions. They are commonly found in fermented foods such as yogurt, kefir, sauerkraut, and certain dietary supplements.

Understanding the role of probiotics is crucial for recognizing how they contribute to health, particularly in relation to gut microbiota balance and overall digestive health. Their beneficial effects are linked to their ability to compete with pathogenic bacteria, enhance the gut barrier function, and produce metabolites that can have positive effects on the host's health, such as short-chain fatty acids.
