The Link Between Gut Health and Biological Aging

Your gut is home to trillions of microbes—and they’re doing more than helping you digest. The gut microbiome influences inflammation, immune function, mental health, and even how your genes are expressed. A balanced gut may slow aging, while dysbiosis (microbial imbalance) can accelerate it. In this article, we unpack how your gut health is deeply linked to your biological age, the role of the gut-brain axis in epigenetics, and practical ways to feed your longevity-supporting microbes through diet, lifestyle, and (when needed) smart supplementation.
