The Human Microbiome

The human microbiome consists of the trillions of microorganisms—bacteria, viruses, fungi, and other microbes—that live mainly in our gut and on our skin. These tiny organisms play a vital role in our health by aiding digestion, producing vitamins, fighting harmful pathogens, and supporting our immune system. The balance of these microbes can influence everything from allergies to mental health. While many are beneficial or harmless, disruptions in the microbiome, such as through antibiotics or lifestyle factors, can impact overall well-being. Understanding and maintaining a healthy microbiome is increasingly recognized as important for overall health.
