Sorry to hear about your co-worker being sick, possibly from long term use of face masks. I would suggest trying NAD+ cell regenerator. I took my wife to her Endocrinologists yesterday and out of the blue they are going back to requiring face masks to enter their office. I guess they don’t trust the science.
Hmm. Thanks for the info?
But Nicotinamide Riboside? Does that have anything to do with the form of Niacin we don’t want to take?
