PatchMD NAD Total Recovery Topical Patch (30-Day Supply) NAD is the chemical term for a molecule that reacts with oxygen in the mitochondria in every cell of your body in order to create energy to sustain every aspect of daily life. Lack of this essential cellular fuel has shown to be linked to chronic fatigue, depression, anxiety, alcohol and drug addition, weakened immune system, headaches, sleep problems, memory disturbance, focus, and concentration abnormalities. NAD deficiency may be an unrecognized epidemic of cellular disease.* How To Use Apply patch daily to an area with little or no hair, i.e., shoulder, back or hip. For best results, it is recommended to wear PatchMD patches for 8 hours. There is no additional benefit wearing the patch longer than 8 hours. Avoid using any lotion or cream in the same area as it will inhibit absorption. Patch is not waterproof. Patches May also be worn overnight while you sleep. Multiple patches can be worn at the same time. *These statements have not been evaluated by the Food and Drug Administration.
