摘要: 我国处于亚健康状态的超重或肥胖人群与老龄化人口都在逐年上升,在衰老和肥胖过程中,烟酰胺腺嘌呤二核苷酸(Nicotinamide Adenine Dinucleotide,NAD+)水平会发生系统性下降。NAD+是细胞能量代谢,调节细胞机能,影响衰老的关键靶点,因此通过补充NAD前体以改善生理机能,延缓衰老已经成为目前研究热点。β-烟酰胺单核苷酸(Nicotinamide mononucleotide,NMN)是动物体内内NAD+代谢的中间产物,也是目前最直接高效的NAD+补充前体。但是NMN对生理机能存在多方面多器官的复杂影响,而且人体试验与动物试验结果并不一致,服用量也尚未确定。本文综述NMN到目前为止的动物,人体试验结果,旨在探究补充NMN对动物、人体生理机能的影响,机制,剂量,不良反应,为未来NMN研究与应用提供思路。

Abstract: The overweight or obese population in sub-health status and the aging population in China are increasing year by year. The cellular level of nicotinamide adenine dinucleotide (NAD+) decreases dramatically with the process of aging and obesity. NAD+ is the key target of cellular energy metabolism, regulating cell function and delaying senescent process . Therefore, it has become a research highlight to improve physiological function and delay aging by supplementing NAD precursors. β-Nicotinamide mononucleotide (NMN) is an intermediate product of NAD+ metabolism in animals, and it is also the most direct and efficient NAD+ supplement precursor at present. However, NMN has complex effects on different organs in many aspects of physiological function, and the results of animal tests are not consistent with human tests , and the dosage has not been determined. This paper summarizes the recent results of NMN animal and human experiments, aiming to explore the effects, mechanisms, doses and adverse reactions of NMN supplementation on animal and human physiological functions, and provide ideas for future researches and application of NMN.
