David Sinclair Supplement Stack: What I Learned After Trying It Myself

Here’s a wild stat that got me hooked — David Sinclair, a Harvard genetics professor, has said his biological age reversed by 10 years. Ten years! When I first stumbled across his supplement routine a couple years ago, I was equal parts skeptical and fascinated. I mean, who wouldn’t want to slow down aging?

If you’ve been curious about the David Sinclair supplement stack, you’re not alone. This guy is basically the rock star of longevity science, and his daily regimen has sparked a massive conversation about anti-aging supplements. So let me walk you through what he takes, what I’ve personally experimented with, and what you should honestly know before diving in.

Who Is David Sinclair and Why Should You Care?

David Sinclair is a professor at Harvard Medical School and the author of Lifespan: Why We Age — and Why We Don’t Have To. He’s been researching the biology of aging for over two decades. His work focuses on sirtuins, NAD+ pathways, and epigenetic reprogramming — fancy terms that basically mean he’s trying to figure out how to keep our cells young.

What made him a household name, though, is that he’s incredibly transparent about his own supplement routine. He’s talked about it on podcasts, in interviews, and in his book. That kind of openness is rare in the scientific community, and honestly, it’s refreshing.

The Core Supplements in Sinclair’s Stack

Alright, let’s get into the good stuff. Based on what Sinclair has publicly shared over the years — mostly through his appearances on podcasts like The Joe Rogan Experience and his own social media — here’s his reported daily regimen:

• NMN (Nicotinamide Mononucleotide) — 1 gram daily: This is the big one. NMN boosts NAD+ levels, which decline as we age. Think of NAD+ as fuel for your cells’ repair mechanisms.
• Resveratrol — 1 gram daily: Usually mixed with yogurt because it’s fat-soluble. Resveratrol activates sirtuins, the proteins Sinclair has studied for years.
• Metformin — 800 mg: This is actually a prescription diabetes drug, but Sinclair takes it off-label for its potential anti-aging properties. He’s mentioned skipping it on days he exercises, since it may blunt some exercise benefits.
• Vitamin D and Vitamin K2: Pretty standard stuff for bone health and immune function.
• Low-dose aspirin: For cardiovascular health.
• TMG (Trimethylglycine): Added to support methylation, which NMN supplementation can potentially affect.

Now, I gotta be upfront — this stack has evolved over time. Sinclair has tweaked things publicly, and what he took in 2020 might not be identical to what he takes today. Always check his latest interviews for updates.

My Personal Experience With Parts of This Stack

I’ll be honest, I didn’t go full Sinclair mode right away. That felt reckless. I started with NMN and resveratrol about 18 months ago because those were the easiest to get without a prescription.

The first month? Nothing dramatic. I was kinda disappointed, actually. But around week six, I noticed my energy levels in the afternoon were way more stable. That 2 PM crash I’d been living with for years just… softened. Was it placebo? Maybe. But I’ve stuck with it, so that tells you something.

The resveratrol was a pain at first because I kept forgetting to take it with something fatty. I’d just toss it back with water and wonder why nothing was happening. Rookie mistake. Now I mix it into Greek yogurt every morning, just like Sinclair suggests.

I did NOT mess around with metformin without talking to my doctor, and neither should you. Seriously. That’s a prescription medication with real side effects.

Important Caveats You Shouldn’t Ignore

Here’s where I put on my responsible adult hat. Sinclair himself has said his routine is a personal experiment, not medical advice. The National Institute on Aging hasn’t endorsed any specific anti-aging supplement protocol yet. Much of this research is still emerging, and what works in mice doesn’t always translate to humans.

Also, quality matters a ton. The NMN market is flooded with sketchy brands. I learned that the hard way when I bought a cheap bottle off Amazon that turned out to have questionable purity. Look for third-party tested products — it’s worth the extra cost.

So, Is It Worth Trying?

Look, I’m not gonna tell you this stack is some magic fountain of youth. But I genuinely believe the science behind NAD+ and sirtuin activation is promising, and Sinclair’s transparency about his regimen has been a gift to the biohacking community. If nothing else, it’s gotten millions of people thinking more seriously about longevity and healthspan.

My advice? Start slow, do your homework, and always — always — talk to your healthcare provider before adding anything new to your routine. Customize what makes sense for YOUR body and YOUR goals. What works for a Harvard geneticist might not be the right fit for you, and that’s perfectly okay.
