Hello
As I do have mitochondrial damage due to fluoroquinolone toxicity I read Turnbuckles thread on manipulating mitochondria with great interest.
About one year ago I started to take NAM + R cyclically. I always felt euphoric and energetic on the day of taking it. And in the days that followed I got muscle and tendon pain which I attributed to the reduced mitochondrial mass (mitophagy due to increased fission).
However then I observed that I could tolerate less and less NAM + R and the pain reactions became stronger and stronger and lasted for weeks after taking NAM + R for just one day.
Last year I could tolerate two days of 1,7g NAM + R in the beginning and had only slight muscle pain for some days - and this year doses of 1x 400mg NAM + R almost crushed me and set my achilles tendons and muscles all over my body on fire for over two weeks.
Three months ago I switched to NR and get the exact same reactions. I never take NR more often than one day per week.
I took 1x 175mg NR 10 days ago. As always I felt euphoric and good on the day of taking it, but now it feels like my whole body is inflamed and I can hardly walk more then 300 meters because of the knee pain and burning achilles tendons.
At the beginning I welcomed these symptoms and hoped that my defective mitochondria were cleared up.
But now I have the feeling that I have developed a sensitivity to the smallest doses of NR?
I know some of you have this issue with resveratrol but are there others who have it also with NAD + precursors?
Any ideas on that? Will stop taking NR now and hope that I return to baseline over weeks and months.
In the weeks after such a "NR flareup" I noticed that my body reacts with extra pain and tendon burning after every meal (whether carbs are included or not) and I'm already on an anti-inflammatory diet. So I suspect NR is somehow messing with my mitochondria and my immune system.
