Understanding metabolism and aging with Charles Brenner

This episode is with Charles Brenner. He is the Alfred E Mann Family Foundation Chair in the department of Diabetes and Cancer Metabolism. His research focuses on disturbances in nicotinamide adenine dinucleotide (NAD), the central catalyst of metabolism, in diseases and conditions of metabolic stress.

Here we talk about what is metabolism?, NAD system, factors affecting NAD system, ageing, anti-ageing research and how NAD system can be used in health?
