NAD Collapse: The Real Reason You're Getting Tired

Today I want to take you into a topic that has become one of the most fascinating areas of modern metabolic science, and honestly, it’s something I had heard about before but had never fully explored until recently. The molecule is called NAD, and once I started digging into the research, I realized it sits right in the middle of many of the things we talk about all the time on this podcast — metabolism, mitochondrial health, insulin sensitivity, aging, brain function, and even how the body repairs itself. What scientists are beginning to understand is that NAD is deeply connected to the ability of our cells to produce energy. When researchers study aging, they consistently notice a pattern. Cells do not necessarily lose their machinery completely as we get older, but that machinery becomes less efficient. Energy production slows down, repair systems work more slowly, and cells become more vulnerable to stress.
