Had planned to thank you for this, before you suggested it.
At 83 I have tried most variations of NMN and NR, with really no apparent benefit.
My second heart op last year and felt a bit adrift, so was persuaded by you ( video ) to try NMNH, with little hope.
Quite extraordinary, but the product just does seem to work. Better optimism, outlook and energy, and rather suspect on this until I croak.
Thanks again for some honest stuff.
Roy.
