"Why David Sinclair’s Supplement Stack...

Just saw this:

 

 

 
"Why David Sinclair’s Supplement Stack Keeps Changing"
 
 
 
"When the antiaging and longevity scientist David Sinclair first published his personal anti-ageing supplement stack, I thought it was unusually credible. He was a Harvard scientist telling us about a regimen that appeared to follow directly from his own scientific research: boosting NAD+, activating sirtuins, engaging AMPK pathways and combining these with lifestyle choices like fasting and exercise. At the time, I thought it was coherent, mechanistic and based on a specific theory of ageing.
 
Years later, however, my confidence has largely evaporated: not because the individual supplements lack antiaging benefits, but because the stack itself has become unstable.
 
His supplement regimen has changed repeatedly, often on a yearly basis. Supplements are added, removed, reintroduced and removed again. Each change is presented as refinement, but taken together they raise an uncomfortable question: if the science was really driving these decisions, why is there so little convergence?
 
Ageing science in humans moves slowly, and evidence accumulates over long timeframes. Annual reversals in personal supplement protocols are, therefore, unlikely to be based on decisive new human data. Instead, they show something else: a continual hypothesis-cycling based on animal studies, in-vitro work and emerging trends in the longevity community. While this kind of evidence is useful for research exploration, it is not strong enough to justify confident, frequently changing supplement prescriptions.
 
This emphasises an important distinction that often gets forgotten in longevity discussions: mechanistic plausibility is not the same as validated intervention. Many of the supplements Sinclair currently takes (NMN, resveratrol, spermidine, fisetin and berberine) have very plausible anti-ageing mechanisms. Some even have sound and encouraging early data. But plausibility alone does not explain why a protocol should keep mutating if it is truly evidence-led. In longevity supplement science, recommendations gradually narrow as weak candidates are discarded and strong ones remain. What we see here is not narrowing, but frequent rotation.
 
Another factor is Sinclair’s evolving public role. Early on, he spoke primarily as a scientist. Over time, he has also become a central figure in the longevity influencer community. That brings different incentives: visibility, novelty, relevance and personal branding around “what I take”. In that environment, his frequent supplement updates signal progress and authority, even when the underlying evidence has not meaningfully changed.
 
None of this means Sinclair is acting in bad faith. It just mean that his supplement stack should be understood for what it is: a personal supplement regime experiment that he is conducting on himself, which is continually revised, and is exploratory rather than definitive. It is not a scientifically validated anti-ageing protocol, and it should not be seen as one.
 
The irony is that his original stack inspired confidence precisely because it appeared stable and theory-driven. Its constant evolution has had the opposite effect."

Does Sinclair add Quercitan to his Resveratrol anymore?

Seems like a pretty good stack to me - pretty close to what most bio-hackers use nowadays.

Looks a good stack to me too .. but strange: metformin and berberine together? really necessary? did not study this in depth though .....

He also has statins, which are not the most healthiest thing to have, seeing as there are better natural and safer alternatives.

Indeed, his stack seems "medication"-heavy.

 

Which could shorten life.

It looks like he is throwing the kitchen sink at it. 

 

Probably he is seeing deterioration at age 56 and it trying everything he can to halt it.

 

But with a stack that complicated you are going to have to add one thing at a time, very carefully, get the dose just right, before you add another component. Somehow I don't think he's done that. The time scales are too short. 

 

More likely he is reading papers, thinking, yeah X has good evidence, I'll add it and just expect to live longer. Then he'll only throw it out if side effects are really overt.

Yes, that sounds like his strategy. 

And the lack of consistency will probably produce variable results.

Rapamycin is notably absent.

I am likely recollecting badly but in case wasn't he making a case of low dose antiviral as valacyclovir to reduce impact of herpes infections and dementia risks? If we screen for cardiovascular say w statins and much of the rest for cancer we would progress, right? Maybe Sinclair never touched on this (cannot find why I have thins in mind ...) but curious if you encountered something similar.

This forum is so absurd that someone will select "disagree" to a clearly true statement.

 

I said "rapamycin is notably absent". Do you see it in his stack? if it's not in his stack, it's absent from his stack. 

 

This is notable because rapamycin has best support in animal studies as a life extending treatment.

Though I didn't tag with 'disagree', you maybe still oversaw? In the post listing his stack, rapamycin is mentioned as the 2nd last item:
 

Low-Dose Aspirin

Statin

Rapamycin

Metformin

 

In the first post linked to webpage, one can read more detail:

 

Rapamycin ~6 mg 4x per year

mTOR inhibitor (Rx)

 

But I'm not familiar with his former stack. Does anyone know which items changed?

Different pathways I believe. I do the same thing. Its a good stack.as good as it gets with what's available. I also use methyelene blue.

Right, my bad. 

 

6mg 4x per YEAR??? 

I have been taking 8mg every 9 days.

Are you taking Rapamycin as a supplement, or for a medical reason?

osris's Photo osris 04 Feb 2026

I’ve been reading about rapamycin. it’s like a “super” anti-aging drug. Basically, it slows down mTOR signaling which seems to be a big reason we age. The way I understand it, evolution only meant this signaling to be active when we’re growing up. After that, it doesn’t really switch off, so it just keeps running. It's like a program on a new PC that you can’t uninstall once the PC is old , and so keeps using up resources and wearing the hard-drive down. Rapamycin slows it down so the body can catch up on repairs.

Rapamycin is an immunosuppressant, taken by transplant recipients to avoid rejection. I assume it come with a whole list of adverse affects. Taking something that takes away your immune system seems counter productive when you are trying to live forever.

Rapamycin is called an immunosuppressant in transplant medicine, but at the low or intermittent doses studied for anti-aging, it doesn’t weaken the immune system. In fact, it can rejuvenate immunity, improve vaccine responses, and reduce infections in older adults. Serious immunosuppression only happens at the high, chronic doses used in transplants, not at the doses relevant for longevity.

Very interesting, thanks for the information.

You're welcome.

 

In mice, it can boost lifespan by about 3-4 months (roughly 7 human years). But for me, a true longevity substance would extend life by several decades.

So even though rapamycin is the best mTOR modulator we know of, it is not all that great.
