Probiotics are beneficial bacteria that support digestive health by balancing the gut microbiome. They aid in the breakdown of food, enhance nutrient absorption, and help prevent or alleviate digestive disorders such as diarrhea, constipation, and IBS. Probiotics can also strengthen the immune system, reduce inflammation, and contribute to mental health by impacting the gut-brain axis. Incorporating probiotic-rich foods like yogurt and fermented products can provide these benefits.
