Nicotinamide mononucleotide (NMN) is a derivative of the B-vitamin niacin that dramatically improves health and longevity by serving as a precursor to NAD+, a compound that plays a crucial role in energy production, metabolism, and gene expression in the body.
NMN works by replenishing diminished NAD+ levels, which naturally fall at a rate of about 1% per year. A 50-year-old person, for example, has about half of the NAD+ they had in their youth. Why is NAD+ important? Because NAD+ is a coenzyme found in all living cells. It is required for all of the body’s fundamental biological processes and is absolutely essential for life.
NAD+ helps transfer energy from fatty acids and glucose to the mitochondria (the power plants of our cells), which converts them to ATP (cellular energy). Since the mitochondria are the energy producers for virtually every cell in the body, improving the function of the mitochondria can have wide-ranging health benefits — including improved energy.
