Probiotics are typically found in fermented foods such as yogurt, kefir, kimchi, sauerkraut, and miso. These foods contain live beneficial bacteria that support gut health and the immune system. Incorporating probiotics into the diet can improve digestion and balance the gut microbiome. Certain supplements also provide concentrated forms of probiotics, catering to those who may not consume enough fermented foods. Regular intake of these foods can lead to various health benefits, including improved nutrient absorption and enhanced mental well-being.
