What NAD+ Is
NAD+ is the coenzyme every cell uses to make energy; levels fall with age, stress and poor sleep. It is taken as a subcutaneous injection two to three times a week, or an IV ($399 for 250 mg), and most people notice it in days.
What Glutathione Is
Glutathione is the body's main antioxidant, injected because the oral form is poorly absorbed. It is taken as a subcutaneous injection twice a week, or a $90 nurse-given shot, and most people notice it in 4 to 8 weeks for skin.
