Why we quote Baur
He co-authored the 2006 resveratrol mouse paper that launched the field, and has since published some of the most careful work on what NAD precursors actually do to tissue pools.
Joseph Baur, PhD is one of the researchers quoted here; the others quoted alongside Joseph are listed with the same disclosures.
Where they stand, and who pays
Academic, and says plainly that he has not adopted a personal NAD regimen because the evidence does not support one.
Stating this next to the quote rather than at the bottom of a disclosures page is the whole point. A concession made against a commercial interest is stronger evidence than a neutral summary; a claim made in line with one is weaker. You cannot weigh either without knowing which you are reading.
Everything we quote them saying
All 3 lines, verbatim, in the order they appear in the site's citation index. Each one links to the recording and to the page it is used on.
Exercise-trained older adults, their NAD levels in the muscle actually aren't even statistically significantly different from those young adults.
Used on What Is NAD? The Coenzyme, the Plus Sign and the B3 Link
If the mice got antibiotics first, so they don't have a microbiome, then nicotinamide riboside doesn't really work so well.
Used on NMN vs NAD vs NR: What the Comparison Actually Rests On
Most studies are typically using about 500 milligrams per kilogram of NR, which is about 35 grams a day for a 70 kilogram human. Human studies are usually using about one gram.
