Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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
