Core Tip

Core Tip: Frailty is defined as a decrease in the reserve and restoring capacity of the body. It is recognized that oxidative stress (OS) is involved in frailty in multiple ways; however, the underlying mechanisms are still unknown. The association between the gut microbiota (GM) and frailty was recently reported. Herein, we propose that OS is involved in the association between the GM and the occurrence of frailty syndrome. The role of the imbalance between OS and dysbiosis is discussed in this review.
