It’s a fundamental driver of our health and longevity, and we’re now learning how boosting NAD levels might offset and improve the effects of aging.  On today’s episode, I’m excited to talk to Dr. Andrew Salzman all about NAD—how it is a key component involved in mitochondrial production, and is a critical substrate for several enzymes, including sirtuins, which play key roles in healthy aging, weight management, metabolic syndrome, and metabolism. Dr. Salzman is a physician, inventor, professor, and biomedical entrepreneur. Dr. Salzman received his medical degree from Harvard University and has spent decades in drug discovery and development, raising over $165M in NIH grants for research. In addition to 50 patents, Dr. Salzman is credited with a breakthrough discovery in cellular DNA repair, which led to the world's first clinical application for successfully treating breast cancer caused by mutations in BRCA1 and BRCA2 genes. Millions of patients are benefiting from discoveries by Dr. Salzman in areas including mitochondrial health, gastrointestinal microbiota, damage caused by inflammation and oxidative stress to human cells and DNA, autoimmune disease, and cancer.
