Bryan Johnson found both NR (Tru Niagen) and NMN (Jinfiniti) effective in raising intracellular NAD+ levels to an equivalent of age 16 after 90 days of each.

“NR vs NMN 180 day trial results: both worked to get my intracellular NAD to level age 16 equivalent (recent 54.6μM)”

“NR vs NMN? I used each for 90 days & both were effective in getting my intracellular NAD levels to age 16 equivalent, 31 yr age reversal as semi-indirect bioage marker.”

“I used each for 90 days & both were effective in getting my intracellular NAD levels to age 16 equivalent, 31 yr age reversal as semi-indirect bioage marker.”

“Niogen, yeah, I um I do NR with Niogen. We tried NMN uh and NR both increase my intracellular NAD levels to age 16. So they both work.”

“they both worked they both allowed me to achieve NAD levels equal to a 16 year old”

“NR generated even higher levels of NMN.”

“Now, again, you raise the question. We have no idea if it's getting in the mitochondria. Is it getting in the cell? Is it getting in the... Now, we do know in animal studies, I think that has been shown that... Because it's affecting the mitochondria, like I said, those animal models of myopathy and stuff and mitochondrial function was improved and all that stuff. So in animal models, it obviously is affecting mitochondrial function. So it must be getting to the right place.”
