Available in doctor's offices only, the 500mg capsule is here!. NAD+ is a vital coenzyme, naturally produced in the body, that promotes cellular repair. NAD+ levels decline when you undergo metabolic stress. For example, when a virus attacks your body, your cells expend immense energy to fight back by activating powerful immune responders. But viral infections may deplete your NAD+ levels by up to 80%, leaving your cells vulnerable.
Tru Niagen® Increases NAD+ to Keep Your Cells Resilient.*
We eat to nourish and energize our bodies. You can think of food as a source of energy, much like a battery. A battery won't power a lightbulb unless it's connected with the right wires and circuits. And cells can't do anything with the energy stored in that food unless they have the right molecules. One of these molecules is NAD+.
NAD+ acts like the wires connecting a battery to a lightbulb—without NAD+ available to convert food energy into cellular energy, cells would be left in the dark.
