NMN究竟是什麼呢？為什麼能夠抗衰老？

研究發現，NMN是體內的一種關鍵性輔酶NAD+的前體物質。 NAD+既是細胞內DNA修復系統的重要原料，也是細胞核與負責能量合成線粒體間的關鍵聯絡因子。同時，人體內NAD+含量與具有延長壽命和抑制衰老作用的sirtuins蛋白家族的活性密切相關。人體各種所需物質都需要輔酶來合成。關於NMN的逆齡、抗衰老作用，其實都是在基於NAD+合成後的輔助功能。 衰老的核心機制是細胞基因受損和線粒體能量生成減少，導致細胞提前凋亡或者活力下降，引起癌症、糖尿病、心血管疾病、癡呆等很多疾病因人體衰老而發病率增加。

NMN是人體固有的代謝產物，它可以直接轉換為關鍵性輔酶NAD+。因NAD+是人體近一半代謝活動不可或缺的物質，但隨年齡增長而快速下降。所以服用NMN可將NAD+水平提高，從而使細胞的能量水平和基因修復能力恢復到年輕態，達到延緩甚至逆轉衰老的效果, MN保護心腦血管功能/NMN延緩血管衰老/NMN防治心腦血管疾病/NMN防治動脈硬化/NMN減輕腦出血損傷.

人体每天补充NMN蕞好控制在每日服用量1g之内，如果是45岁左右的人服用量在300mg左右，65岁以上的老年人的话每天应补充600mg左右的nmn，可以在饭前食用，也可以在饭后食用，蕞好是用温水冲服，这样可以让身体吸收的效果更好，如果需要分开服用，蕞好在早晨或者午饭过后吃。因为人体体内有内循环，如果分开服用可以使nmn所产生的作用效率更大。

WHAT IS NMN?

NMN is an entirely natural compound found in our bodies. Various food sources also contain this compound in minuscule amounts. Edamame which has one of the higher contents, only show less than 1.9mg/100g. NMN is a direct and potent NAD+ supplement. Mice given an oral supplement of NMN showed increased liver NAD+ levels in just 10 minutes and showed an increase in muscle tissue by 30 minutes. Increased NAD+ levels stimulate energy DNA repair and SIRTUIN activity. SIRTUINS are the longevity-genes shown to be active during caloric restriction and life-extension in many animal models.

NAD+ helps to breakdown food like sugars into energy.

Promotes Healthy Cardiovascular Function.

DNA Repair - NAD+ is used to repair broken DNA strands.

SIRTUIN Activator - NAD+ is required for our longevity genes to work.

NMN is THE compound used by Harvard Scientists to reverse some signs of aging tissue in mice that started the rush to NAD supplements.

THE SCIENCE

Scientists have now confirmed a direct link between falling NAD+ levels and aging in both animals and human subjects. A breakthrough study published by Harvard scientists in 2013 showed for the first time that some aspects of aging might be reversible. After treating old mice with NMN, several biometric markers that were subsequently measured resembled those of young mice: "the human equivalent of a 60-year old with markers resembling that of a 20-year old". The research and understanding into NAD+ metabolomics are ongoing, but what the science has highlighted thus far, is the importance of supporting and maintaining our NAD+ levels.A long-term evaluation of oral supplementation of NMN in mice was found to be effective at improving NAD+ levels safely. Mice supplemented with NMN vs. a control group showed notable age-associated differences in mass, energy, blood sugar, lipid, gene expression changes, mitochondrial oxygen use, eye function, bone density and immune function with no apparent toxic effects.
