Huberman LabAMA #12: Thoughts on Longevity Supplements (Resveratrol, NR, NMN, Etc.) & How to Improve Memory
CHAPTERS
- 0:00 – 3:50
Intro, Premium Channel, and Research Funding
Huberman opens the AMA episode by explaining the purpose of the Premium channel: to support the free weekly podcast and to fund human-based research on mental and physical health and performance. He describes pricing, matching funds from the Tiny Foundation, and how non-subscribers can listen to the first 20 minutes to evaluate the offering.
- 3:50 – 6:15
Resveratrol’s Fall from Longevity Hype and Role of Grape Seed Extract
The first listener question addresses whether resveratrol actually extends lifespan. Huberman explains the early excitement around resveratrol and grape seed extract, then argues that modern evidence does not support resveratrol as a longevity compound, while still leaving room for some cellular benefits.
- 6:15 – 8:30
Why Huberman Uses Grape Seed Extract (But Not for Longevity)
Huberman details his personal use of grape seed extract as a vascular-support supplement. He describes it as a low-risk, moderately evidenced compound he uses daily as "general insurance" rather than a top-tier or primary supplement.
- 8:30 – 12:00
NAD Pathway Basics and the Rise of NR/NMN
The discussion broadens to NAD pathways and their relation to aging and cellular energetics. Huberman explains NAD’s role in mitochondrial function and introduces NR and NMN as commonly used precursors that attracted a surge of interest in the longevity space.
- 12:00 – 16:30
Huberman’s Personal Protocol with NR and NMN
Huberman shares his specific use of NR and NMN, including dosing, timing, and subjective effects. He experiments with each separately and combined, concluding that they reliably enhance his daily energy without disturbing sleep, while clearly distinguishing this from any evidence-based longevity claim.
- 16:30 – 19:40
Regulatory Changes and Uncertainties Around NMN and Oral NAD
Huberman explains the recent regulatory shift that removed NMN from the general supplement market after it was filed as an experimental drug. He also notes the emergence of oral NAD products and the lack of clear data linking their ingestion to increased intracellular NAD.
- 19:40 – 22:50
Experiencing NAD Infusions: Benefits and Severe Discomfort
Huberman describes undergoing two high-dose NAD IV infusions to combat fatigue and post-illness malaise. He candidly recounts the intense physical discomfort during the infusions and the positive, though anecdotal, effects afterward, while cautioning that no clinical trials yet support this for vigor or recovery.
- 22:50 – 25:10
Debate in the Field: NAD, NR vs. NMN, and Longevity
Huberman notes that leading scientists and clinicians actively debate the merits and mechanisms of NAD-boosting strategies. He frames his own use as personal experimentation for energy, acknowledging unresolved scientific questions about cellular uptake and true anti-aging effects.
- 25:10 – 28:10
Metformin, Berberine, and mTOR: Why Huberman Abstains
The conversation shifts to metformin, berberine, and the mTOR pathway as longevity targets. Huberman, familiar with mTOR from his own lab work, explains why he avoids both berberine and metformin for longevity given side effects and the current lack of compelling human lifespan data.
- 28:10 – 30:40
Rapamycin and mTOR: Promising Science, Not in Huberman’s Stack (Yet)
Huberman outlines ongoing rapamycin research, particularly in the context of mTOR and lifespan across species, including dogs. He respects the work of researchers and clinicians exploring rapamycin but concludes that its side-effect profile and current data make it unsuitable for his personal use for longevity at this time.
- 30:40 – 35:30
Foundations of Longevity: Sleep, Exercise, Nutrition, Stress, Light, Relationships
Huberman closes the scientific section by strongly re-centering the discussion on fundamental behaviors that have far greater and better-established effects on longevity than any pill. He gives specific exercise targets and highlights sleep, circadian alignment, nutrition, stress modulation, and healthy relationships as the real foundation of both healthspan and lifespan.
- 35:30
Closing: Physician Guidance and Premium Channel Purpose
Huberman ends by stressing the need for medical consultation before altering any supplement or drug regimen. He reiterates the mission of the Premium channel—funding human research and delivering in-depth, practical tools—and reminds listeners of subscription options and matched research funding.
