The original version of the published Article contained an incorrect citation for reference 20 “Hubbard, B. P. & Sinclair, D. A. Measurement of sirtuin enzyme activity using a substrate-agnostic fluorometric nicotinamide assay. Methods Mol. Biol. 1077, 167–177 (2013).” The citation for reference 20 has been changed to “Cheng, Y. et al. SIRT1 activation by pterostilbene attenuates the skeletal muscle oxidative stress injury and mitochondrial dysfunction induced by ischemia reperfusion injury. Apoptosis 21 (8), 905-916 (2016)”. The original version of the published Article did not list a source for the placebo pills or the investigational product NRPT in the Intervention section of Methods. The last sentence of the Intervention section of Methods now lists the source for the placebo pills and the investigational product NRPT as follows: “The matched placebo pills and the investigational product (NRPT) were provided by Elysium Health (New York, NY)”. This has now been corrected in the PDF and HTML versions of the Article.

作者更正：重复剂量NRPT（烟酰胺核苷和蝶草烯）可安全，可持续地增加人类的NAD +水平：一项随机，双盲，安慰剂对照的研究

已发表文章的原始版本引用了错误的参考文献20“ Hubbard，BP＆Sinclair，DA使用与底物无关的荧光烟酰胺测定法测量瑟土因酶的活性。方法 生物学 1077，167–177（2013）。” 参考文献20的引用已更改为“ Cheng，Y.等。蕨类植物对SIRT1的激活减弱了缺血再灌注损伤引起的骨骼肌氧化应激损伤和线粒体功能障碍。细胞凋亡21（8），905-916（2016）”。已发表文章的原始版本未在“方法”的“干预”部分中列出安慰剂药丸或研究产品NRPT的来源。现在，“方法”的“干预”部分的最后一句列出了安慰剂药和研究产品NRPT的来源，如下所示：“相配的安慰剂药丸和研究产品（NRPT）由Elysium Health（纽约，纽约）提供”。现在，该文章的PDF和HTML版本已对此进行了更正。
