Probiotics support gut health by maintaining a balanced gut microbiome, which is vital for digestion and overall wellness. These beneficial bacteria help break down food, absorb essential nutrients, and strengthen the gut barrier against harmful pathogens. Probiotics also play a role in regulating immune function and reducing inflammation, potentially preventing various gastrointestinal disorders. Consuming probiotic-rich foods, such as yogurt, kefir, and fermented vegetables, can enhance gut flora diversity, promote regularity, and contribute to mental health through the gut-brain axis.
