Consensus Report
NMN & NAD+
Split Consensus
out of 5
Based on 29 videos (52 hours analyzed) across the experts · Updated 2026-03-19
Stance update (2025): Attia has consistently strengthened his skepticism, moving NMN/NAD from 'unproven' to explicitly categorizing it as 'noise' on his evidence hierarchy.
Expert Positions
The Verdict
This is one of the most divisive topics among our 5 experts. Attia categorizes NAD supplementation as 'noise' on his evidence hierarchy, while Hyman actively advocates for NAD precursors as part of a longevity stack. Huberman personally takes NR and NMN for subjective energy but explicitly not for longevity. Patrick provides the most balanced scientific coverage, noting promising animal data but significant gaps in human evidence.
Where They Disagree
Attia classifies NAD as 'noise' while Hyman's guests recommend high-dose NMN (1000mg) as a core longevity supplement — a fundamental disagreement on the evidence threshold for recommendation.
Patrick notes that NMN and NR break down into nicotinamide, which can inhibit sirtuins — directly contradicting the rationale for taking NAD precursors to boost sirtuin activity.

Where do the experts disagree on nmn & nad+?
Attia classifies NAD as 'noise' while Hyman's guests recommend high-dose NMN (1000mg) as a core longevity supplement — a fundamental disagreement on the evidence threshold for recommendation. Patrick notes that NMN and NR break down into nicotinamide, which can inhibit sirtuins — directly contradicting the rationale for taking NAD precursors to boost sirtuin activity. Huberman takes NR and NMN daily for subjective energy while simultaneously acknowledging the lack of longevity evidence — illustrating the gap between personal experimentation and evidence-based recommendation.
