I recently posted on a study that nicotinamide riboside might be bad for women with current triple-negative breast cancer. I take it, but be prudent with it, if you are a woman.
NMN should work the same. I think that is also easier to find.

Another supplement. I no longer have room to eat actual food due to all the supplements that have become necessary for good health.
I quit smoking some 25 years ago. But maybe the nicotine of the nicotinamide of the Skoal I still chew will have a redeeming quality.
I know, I know it maybe unhealthy. Just saying. It’s a habit, but as Twain said “quitting tobacco is easy, I’ve done it many times.”
Cheers folks
I have been researching the use of NR and the other NAD+ precursor, NMN, for a few months now. The only definitive studies that showed tissue absorption levels have been done on mice. Both NR and NMN were tagged with a radioactive marker so that they could be detected in the mouse tissue when absorbed.
The studies showed that NR and NMN that was orally ingested did not show significant uptake levels in body tissues like the liver, kidneys, or brain. Injecting the mice with the supplements did show up in their tissues, but only at dosage levels that were well above what would be considered safe for humans.
Amazon has recently banned the sale of NMN due to a large amount of fake products being marketed. If you want to biohack these the safest companies would be Tru Niagen and DoNotAge. DoNotAge is made in the UK and is a fraction of the cost of Tru Niagen.
Here’s a link to a video on the studies.
