Bifidobacterium is a type of beneficial bacteria that naturally resides in the human gut, particularly in infants. It plays a crucial role in digestion by helping to break down food and absorb nutrients. This bacteria is also important for maintaining a healthy balance of gut flora, which can support the immune system. In addition to its digestive benefits, Bifidobacterium is often found in probiotic supplements and fermented foods like yogurt. Research suggests that it may help alleviate gastrointestinal issues, enhance gut health, and even improve overall well-being by promoting a balanced microbiome.
