作为维生素衍生物NMN是种天然物质，日本2015年就已经开始卖了，好多用户也已经吃了三年了，市面上也有很多NMN在销售。为何报道说要5年后才能上市呢，这是什么原因呢？

       其实这有一定的误解！市场上销售的NMN是属于Dietary Supplement（食物补充剂），是食品标准；Dr. David Sinclair和DR.Lindsay Wu所说的五年后上市的NMN是抗衰老药物，是药物标准！

       其实这和二甲双胍类似，FDA是不承认衰老是一种疾病的，神药二甲双胍1957年已经面市，但是直到2015年FDA才批准了二甲双胍作为抗衰老药物的临床。因为临床是要经过1/2/3期的，所以虽然作为食物补充剂的NMN已经面市，但是作为抗衰老药物的NMN也许要经过5年。

       作为NAD+最有效的补充剂，NMN的主要的在于成本太高。按照植物中的含量，补充100mg的NMN，要吃掉上百千克的水果，这不现实。

食物中NMN含量

       排除一些纯度不够以及挂羊头卖狗肉的NMN，将市面上广受认可的NMN价格进行比较。实验室级别的NMN比黄金还贵，日本发酵法的NMN次之，酶法的NMN最具竞争力。Herbalmax公司酶法工艺已经将NMN售价降低了五分之一，而香港中文大学的王骏教授全产业链的酶法工艺更是让NMN量产，成本断崖式下降。

       王骏教授凭借其先进的酶法技术实力，和走在NMN抗衰老研究的哈佛医学院的David Sinclair教授和新南威尔士的Lindsay Wu教授进行了深度合作。

 往前看90年多年，人类首次发现维C的惊喜心情和现在发现NMN的惊喜心情颇为类似: 具有一系列神奇功能，且价格较贵！ 但现在维C 不到2元就可以买到，NMN也会随着规模的扩大降低成本！追求长生不老是人类一直以来的梦想，能否到150岁还需要探究，但延年重要益寿也同样重要，相信NMN会让人类征服衰老的进程更进一步。
