NMN (Nicotinamide mononucleotide): The full name is "β-nicotinamide mononucleotide", which is a naturally occurring biologically active nucleotide. There are two irregular forms of NMN, α and β; β isomer is the active form of NMN with a molecular weight of 334.221 g/mol. Because nicotinamide belongs to vitamin B3, NMN belongs to the category of vitamin B derivatives. It is widely involved in many biochemical reactions of the human body and is closely related to immunity and metabolism.
The decline of NAD in the aging process is considered to be the main cause of diseases and disability, such as hearing and vision loss, cognitive and motor dysfunction, immune deficiency, arthritis, metabolic disorders and cardiovascular diseases caused by dysregulation of autoimmune inflammation. Therefore, supplementation of NMN increases the NAD+ content in the body, thereby delaying, improving, and preventing various phenotypes related to aging, or age-induced metabolic disorders, senile diseases, etc.
