every week, i get an email from a desperate parent whose kid has a potentially incurable cancer, asking if they should take #NR, often in a cocktail with resveratrol & other stuff /1
experiences like these make me shudder at the 💩 being peddled in the name of "anti-aging." no phd scientist should tell any such parent that their kid's rare malignancy is curable with their favorite elixir /2
i remind ppl that NR is active in many rodent models of human diseases & conditions of metabolic stress in which the NAD system is under attack (heart failure, fatty liver, neurodegeneration, central brain injury, etc) /3
while many of these conditions are age-associated, aging is not 1 thing & clearly their kid's cancer is a distinct entity that has little resemblance to the biohacking experiments of grown men & women /4
i do believe that ppl can age better & it usually starts with increased physical/mental activity, matching food consumption to energy expenditure & avoiding the killers of smoke, gun violence, drugs, SARS-CoV-2, etc /5
the NAD system comes under pressure from many types of common stresses including sun (DNA damage), oxygen (ROS damage), alcoholic liver damage & coronavirus infection. this is precisely the reason why there are so many clinical trials of NR for conditions of metabolic stress /6
& why there could be health claims for NR in the future. folks are barking up the wrong tree if they expect human lifespan experiments to be completed with NR or any other molecule. /7
we advise NR trialists to select the target population carefully & do the study for sufficient time to see results while combining with approaches like exercise that are complementary doi.org/10.1093/ajcn/n… /8
also, please stop putting NR in a basket with debunked snake oils like resveratrol or pterostilbene. eating veggies & blueberries is great for 1000s of reasons but it doesn't help legitimate NAD research to be associated with junk science /end
PS. If you are one of those parents, know that my thoughts are with you. Ppl like myself & @ranjitbindra are working on specific cancer approaches for specific tumors. Pls don’t be suckered by bad science, false claims & book promotion. False promises hurt ppl every day

today @davidasinclair is telling the world that he has achieved age reversal with chemical cocktails
he submitted the paper on June 30 & it was accepted on July 4 by a journal of which he is coeditor-in-chief
paper was sent to me 3 days ago by a reporter for comment
reporter was told it is a "groundbreaking study" & "the first chemical approach to reprogram cells to a younger state"
reason WSJ didn't cover that paper is that ppl have been reporting chemical compounds that drive conversion of cells to induced pluripotency for the last 10-15 years
all of the compounds in today's paper were previously reported by others, mostly in 2013
there's a peer review failure today doi.org/10.1016/j.cell… in which an individual with 59 collaborators claims to have tested the information theory of aging
he did not test the information theory of aging
the claim is that he induced dsDNA breaks that are easily repaired, don't cause a DNA damage response or mutagenesis or cell death--only an epigenetic change
he knows this is not true because his co-first author & he published this paper in dec '21
there are a few issues being addressed here. let’s start w safety
human placebo controlled trials have never shown adverse events attributable to Niagen. note that LDL-C is raised in humans w Basis & pterostilbene alone
the class of compounds to which NR belongs is vitamin B3
there are decades of human data on these molecules showing human safety. niacin is unique in causing flushing but nicotinamide was tested in large Australian skin cancer and was shown to be cancer-preventative in ppl
there’s a hierarchy of evidence w human RCTs (and meta-analysis of RCTs) on the top. human case reports & good quality rodent studies are lower. cell studies are lower. poorly conducted rodent and/or poorly conducted cell studies are garbage in/garbage out
