You can tell a lot about someone’s age by checking their NAD levels. NAD is a vital molecule for energy production and cellular function, but its levels decline after age 30, leading to signs of accelerated aging [1,2]. While it’s possible to restore NAD levels with expensive IV infusions of NAD infusions, research shows that the right precursor molecules can help the body produce its own NAD naturally [3]. Qualia NAD combines three key precursors — nicotinamide riboside, niacin, and niacinamide

I’m Deepak Chopra. As a physician and author of over 90 books on health and wellness, I believe understanding how we age—and what we can do about it—is essential to living well. One of the most fascinating discoveries in aging research is the concept of zombie cells—also known as senescent cells. These are old, worn-out cells that stop functioning but don’t die. Instead, they linger in the body, interfering with tissue repair and healthy function [1]. Over time, they contribute to fatigue, slugg
