Stats: 70yo, 179lb, 6'1", good health, physically active
I have been taking 500mg of HPN Niagen (4 caps) for a couple of months without much effect.
I take it first thing in the morning with coffee before eating, along with a couple of ibuprofen and 5000iu D3.
No other supplements. I try to eat lots of polyphenols: nuts, berries, red wine, apples, etc.
When I first started Niagen, it seemed my dreams were more vivid, but that went away quickly, and I
have no other psycho active experiences to report.
In the last year I have had some problems with arthritis in my lower back and neck, but Niagen has not helped this.
I was taking C60oo weekly for several years, but I stopped taking C60oo about 6 months ago to see if was
connected with the arthritis. Since they seem unconnected I may resume weekly teaspoon of C60oo.
2 or 3 times a week I play tennis, run, and lift weights, so I keep close track on my endurance and strength, and
there has been no significant changes since Niagen. My tennis serve has not improved :(.
For folks who have been asking for VO2max data, I have some but you probably will not be happy with its validity!
A few months ago, my gym got some new stair steppers (Matrix C5X ClimbMill by matrixfitness.com) and I found
a "WFI Fitness Test" setting that calculates?!? VO2max from stair climbing results without any breath analysis.
You input age, weight and height and the stepper continually ramps up your step rate until you hit a maximum heart rate
as measured by heart rate sensors on the machine hand grips. Here is the manufacturer's description:
"The WFI (Wellness Fitness Initiative) protocol is a test used by firefighters to evaluate aerobic fitness capacity as part of
pre-employment testing and annual fitness testing. This assessment is a series of intervals lasting a maximum of 16 minutes,
where the speed is increased every minute until the Target Heart Rate is exceeded for 15 seconds. When the test is complete,
the display provides a summary of VO2max, Highest SPM, Elapsed Time and Target Heart Rate. This is a speed-dependent program."
I am not sure how accurate this VO2max is, but I have been using it as regular workout to get my heart rate up to ~95% for
a minute or so, several times a week.. I have to input an age of 45, rather than my real age, to get the maximum heart rate setting to 150.
I consider this exercise to be my minimalist form of interval training for those of us who are lazy and have short attention spans.
MartixFitness seem to set the heart rate limit for the WFI Fitness Test by the formula (220-age)*0.85. More sophisticated formulas
suggest my maximum heart rate is about 157, so I want to get up to at least 150 several times a week.
Note that in my experience the WFI test estimate of VO2max does not seem to vary much with age - I get similar VO2max results
with ages I have tried from 30 to 70!
My WFI test only takes about 7 minutes (not 16), as the step rate ramps up from about 40 to 100 steps per minute,
and it takes me about twice as long just to cool down. According to their calculation, my VO2max has been
around 40.5 with a variation of -1 to +2 (units?) during the last few months, and Niagen does not seem to have had any effect.
Note that I take the Niagen about 7am and do the fitness test around 10am.
I am now increasing my HPN Niagen intake to 750mg/day (6 caps). Will report back on results of higher dose.
