Longevity Supplements: A Critical Look at Resveratrol, NAD Precursors, Metformin, and Rapamycin, Emphasizing Foundational Health

This AMA episode critically examines popular longevity supplements and drugs, including resveratrol, NR, NMN, NAD infusions, metformin, berberine, and rapamycin. Andrew Huberman shares his personal experiences and current scientific understanding, largely debunking the direct lifespan-extending claims for many of these compounds in humans. He emphasizes that while some may offer subjective benefits or support specific physiological functions, they are not proven to increase longevity. The episode also highlights the Huberman Lab's premium channel's mission to fund human-centric research for mental and physical health and performance, with a dollar-for-dollar match from the Tiny Foundation. Huberman draws crucial distinctions between taking supplements for subjective vitality and energy versus proven lifespan extension. For instance, he takes grape seed extract (containing resveratrol) for vascular function, not longevity, and NR/NMN for perceived energy, not lifespan. He notes the ongoing debate among experts like Dr. Charles Brenner, Dr. David Sinclair, and Matt Kaeberlein regarding NAD pathways and their efficacy. A significant nuance is the FDA's recent ruling reclassifying NMN as an an experimental drug, impacting its commercial availability as a supplement. He also differentiates between the discomfort and expense of direct NAD infusions versus oral precursors. The core recommendation is to prioritize foundational health practices: sufficient quality sleep, regular exercise (Zone 2 cardio, VO2 max, resistance training), quality nutrition, effective stress modulation, strong social connections, and consistent morning sunlight exposure. These basics are presented as having an "out-sized effect" compared to any supplement or drug. For those considering supplementation, Huberman personally takes grape seed extract (400-800mg/day) and a combination of NR (500mg/day) and NMN (1-2g sublingual) for subjective energy, and occasionally uses NAD infusions for post-illness recovery, but explicitly states he does not take metformin, berberine, or rapamycin for longevity. The discussion underscores the dynamic nature of scientific understanding in the longevity field, with ongoing research and active debates among leading experts. It serves as a cautionary tale against premature adoption of unproven interventions and stresses the importance of a critical, evidence-based approach to health. The episode implicitly advocates for a holistic view of health, where lifestyle fundamentals are paramount, and supplements are considered only as potential enhancements, always in consultation with a board-certified physician. The funding model for research through the premium channel also highlights a broader effort to accelerate human health discoveries.

I think by now, 2023, it's fair to say that most of that thinking has been, let's just say, debunked.

I do not take it for its potential impact on resveratrol and resveratrol-related pathways per se and certainly not to extend my lifespan.

I do not take NR and NMN in order to increase my lifespan. In fact, at this point in history, it's unclear and seems somewhat unlikely that increasing NAD is going to increase lifespan.

When I take NR and NMN at the dosages I talked about a little bit earlier, it gives me a lot of sustained mental and physical energy throughout the day.

Nonetheless, you can still find NMN on the open market. You can find it on Amazon. I can't really speak to the purity of one source versus another.

I don't do any of this stuff in these NAD pathways for sake of increasing lifespan. I do it for sake of the vitality and energy effects that I subjectively experience.

I think only by getting your light exposure, sunshine, movement, nutrition, stress modulation, social relationships, et cetera, correct should you even begin to consider supplementation, because supplementation is just not at the foundation of mental health, physical health, and performance.

It is very, very clear that at present there is no supplement or drug for increasing longevity that even comes close to the known improvements in health metrics that relate to longevity that come from getting quality sleep and especially from getting sufficient amounts of quality exercise.

And of course, getting morning sunlight, all of those things combine to have a huge out-sized effect compared to anything that you could take in pill, capsule or infusion.

any time you're thinking of adding a supplement or removing a supplement from your regimen or adding a prescription drug or removing a prescription drug, you absolutely should consult you're board-certified physician.
