NAD, or Nicotinamide Adenine Dinucleotide, occurs naturally in the body, and is found to decrease in production with age. NAD plays a major role in the chemical process of generating energy, as it is one of the most important cofactors for improving mitochondrial function. Mitochondria are intracellular organelles (known as the “energy powerhouse”) where micronutrients are converted to energy-rich ATP molecules. NAD helps the liver break down fats that are essential to provide energy for the body. Boosting NAD levels may help manage a wide spectrum of diseases, ranging from diabetes to cancer.
