Recommended by the people who study this.
The clinical dosing and third-party purity data are what set Healthspanx apart. I now recommend it to patients over 50.
Finally an NMN formula dosed the way the research actually studied it. Transparent COAs sealed it for me.
Recovery and afternoon focus are noticeably better. This is the one supplement I no longer skip.
