In this episode of Stephen McCain podcast, I interview Jin-Xiong She, founder & CEO of Jinfiniti Precision Medicine, which develops and markets Longevity tests to help people maximize their healthspan.

We discuss the importance of optimizing NAD. NAD is a vital coenzyme involved in numerous biochemical processes in the body. It plays a crucial role in energy metabolism, DNA repair, and cellular regeneration. By increasing NAD+ levels, our bodies can more effectively repair damaged cells, improve cognitive function, and enhance energy levels.

NAD supplements have become very popular in the last couple of years. However, we should strive to test and optimize the dose of our supplements to truly get the proven benefits of NAD. 

By the end of the episode, you will know how to easily test your NAD levels in the comfort of your own home. How to interpret the test results. And, learn about a product that has been proven to optimize NAD levels in 90% of the people using it.
