NAD+ Forums

I've been reading there might be another explanation. I started noticing the decrease in lift at the same time I started taking sirtuin 6 activator. Sirtuins use NAD+ right? 

Any form of cardio is good as long as you push yourself. When I use the bike I usually do intervals, for example : 30 seconds medium speed, 30 seconds fairly fast and then 30 seconds as fast as possible. I'd do that for 25 minutes and be drenched in sweat. Or just ride to work on this bike.
