I take it first thing in the morning with coffee before eating, along with a couple of ibuprofen and 5000iu D3.
I dont know if this is relevant to your Niagen but I have the powdered form and you mix it with water of juice. It stated NOT to use hot or warm water but does not give a reason......I wonder if the warm or hot liquid it may render it inactive?
And for what its worth that V02 max result will be way off, their is no way that can be calculated from anything other than you breath analysis.
By the way AV02 max reading of 40 at your age would be phenomenally good..If your true V02 max were 40, then that may be another reason you may not be feeling any benefits from NR as you may be in super fit condition and your NAD levels may be excellent already......Just a thought?
Interesting comments!
I take my Niagen caps with cold water, and then make a cup of coffee. Probably 5+ minutes delay. Just in case I will extend to 10 min.
In my dreams I am phenomenal, but in the real world, not so much.
Lots of geezers are passing me in races and while hiking.
Here is a web page that attempts to correlate VO2max with a 12 minute run.
http://www.exrx.net/.../MinuteRun.html
If I input 1.44 miles in 12 minutes, then the calculated VO2max is 40.5, the same calculated VO2max from my stair stepper.
That is 12/1.44=8.33 minutes per mile pace.
I have done 5k (3.1 miles) races at a 9 minutes/mile pace, so it is not out of the question that I could do 8.3 minutes/mile pace for 12 minutes.
But it is definitely pushing it for me. I will see how long I can last at a 8.3 min/mile pace on a treadmill this weekend.
This suggests to me that the stair stepper VO2max calc is on the high side, but not completely wacko.
My 9 min/mile pace gives a 12/9=1.33 mile distance covered in 12 minutes, and this is equivalent to a 36.6 VO2max according to the web page.
That suggests the stair stepper is about 10% high in its VO2max calculation.
