NMN Powder is a molecule that exists in all living organisms and is a precursor of NAD+(nicotinamide adenine dinucleotide). NAD+is a coenzyme involved in cellular respiration, energy metabolism, DNA repair and other important biological processes, which is essential to maintain cell health and delay aging. As we age, the level of NAD+in the human body gradually decreases, leading to cellular dysfunction and various aging related diseases. Therefore, increasing NAD+levels is considered an effective anti-aging strategy.
