The pursuit of longevity is a deeply rooted aspect of human culture, intertwined with the advancement of medical and scientific knowledge. In recent decades, a significant focus has been placed on understanding the microbiome—our body's complex system of bacteria, fungi, and viruses that reside primarily in the gut. This system plays a crucial role in digestion, immune function, mental health, and more. Emerging research suggests that enhancing microbiome health could be a key strategy in extending not just life expectancy but also the quality of those extended years.
