Bacteria play a crucial role in human health by contributing to the gut microbiome, which aids in digestion and nutrient absorption. They help synthesize essential vitamins, such as vitamin K and certain B vitamins, and support the immune system by outcompeting harmful pathogens. Additionally, beneficial bacteria can influence metabolism and may even impact mental health through the gut-brain axis. Overall, these microorganisms are vital for maintaining overall health and well-being.
