Clinical Trial Summary

The goal of this clinical trial is to test whether activation of telomerase with a dietary supplement (TA-65) improves microvascular function.

Description:

The purpose of this clinical trial is to examine whether activation of autophagy with TA-65 which activates telomerase, improves microvascular function and blood pressure in an older population
