Three years ago in Japan, the first human clinical study for NMN was announced to study if NMN is safe for human consumption. Everyone who studies and consumes the NMN supplement to boost NAD in their body was excited to finally learn if NMN supplementation conferred similar lifespan enhancing attributes to humans that many research studies showed that it did in mouse models.

I will examine the objectives of the Japanese NMN human trial and remark on the recently published results, which have been widely misunderstood. This study’s conclusion was not that NMN was ineffective at boosting NAD levels in the research participants, thereby did not confer health and longevity benefits to them. This potential was not examined.
Instead, what the study did examine and show is that NMN is safe for humans.
