Maybe a noob question...
I'm physically active male in 30s.
Thinking of starting Nicotinamide Riboside supps, but no idea how to measure effectiveness and which ones to try.
1) Which would be the best dosage for me? LifeExtension Europe offers me to buy 100mg and 300mg (maybe other brands you'd recommend)?
2) Which tests should I do (before and after) to confirm the changes of NAD+ levels in my blood/body?
Thank you!
