NAD Expert: How to Support Energy at the Cellular Level

Jim Kwik talks with nutritional biochemist Dr. Andrew Shao about NAD+, a molecule essential for cellular energy production and repair. They discuss why NAD+ levels may decline with age, especially in metabolically active tissues, and how lifestyle stressors like poor sleep, alcohol, and pollution can increase demand on the system. Dr. Shao also explains how to evaluate supplement claims using clinical research and third-party testing, and why foundational habits like sleep, nutrition, and movement remain essential for supporting cellular energy.
