NAD and NAD+ occur naturally in the body. They play a major role in the chemical process of generating energy. NAD+ is probably the most important co-factor for improving mitochondrial function. Mitochondria are intracellular organelles (AKA “energy powerhouses”) where micronutrients are converted to energy-rich ATP molecules for the cell. As we age, our body’s NAD levels gradually drop due to lower intrinsic production and inflammation/oxidative stress caused by environmental factors. This drop in NAD+ can cause fatigue, mental fog, dull and tired skin, and poor sleep quality. Boosting NAD+ may help manage a wide spectrum of diseases and the effects of aging.
