NMN 21000 is an efficient anti-aging nutritional supplement that is rich in NMN (nicotinamide mononucleotide), which is the direct precursor of the most important coenzyme NAD+(coenzyme 1) in the human body. NAD+plays various important roles in the human body, such as participating in energy metabolism, repairing DNA, and resisting oxidative stress, which is crucial for maintaining cell vitality and health. As one ages, the level of NAD+in the human body gradually decreases, leading to aging and the occurrence of diseases. Supplementing NMN can quickly increase the level of NAD+in the human body, thereby delaying the aging process, improving body functions, and enhancing immunity.
