When to Take NMN & NAD+ — Expert Timing Protocols
Expert-analyzed timing recommendations for nmn & nad+ based on what 5 longevity researchers say about when, how, and what to take it with.
Quick Timing Guide
Morning dosing is most common. Sinclair emphasizes pulsatile dosing — cycling on and off rather than continuous daily use. Take with food containing fat for resveratrol co-supplementation.

Full Protocol
Timing
Morning dosing is most common. Sinclair emphasizes pulsatile dosing — cycling on and off rather than continuous daily use. Take with food containing fat for resveratrol co-supplementation.
Dosage
NMN: 250-1000mg daily (Sinclair via Huberman: 1g; Hyman guests: 1000mg; Huberman personal: 1-2g). NR: 300-500mg daily (Huberman personal: 500mg). No consensus dosage exists.
Form
NMN sublingual or capsule. NR (as Niagen) is the most studied form. NAD+ IV infusions used occasionally for acute recovery (Huberman). Stability and bioavailability vary significantly between products.
Notes
NMN is currently restricted as a commercial supplement due to FDA rulings classifying it as an investigational new drug. NR remains available. Exercise and fasting are proven to naturally boost NAD levels and should be prioritized over supplementation. There is no consensus among our 5 experts that supplementation is necessary or beneficial for healthy individuals.
What Each Expert Says About Timing
Huberman has covered NMN/NAD+ extensively through two dedicated David Sinclair episodes and a personal AMA on longevity supplements. He personally takes NR (500mg) and NMN (1-2g) daily for subjecti...
Attia is the most skeptical of our five experts on NMN/NAD+ supplementation. Across at least 8 episodes — including dedicated discussions with David Sinclair, Matt Kaeberlein, Nir Barzilai, and Rho...
Patrick provides the most scientifically comprehensive and balanced coverage of NAD+ biology among our five experts. She has a dedicated video on NAD+ in aging covering NR and NMN, plus extensive d...
Bryan Johnson's analyzed videos cover his Blueprint protocol in detail — including his supplement closet, longevity stack, and data-driven approach — but NMN and NAD+ precursors are not explicitly ...
Hyman is the most enthusiastic advocate for NAD precursors among our five experts. Across multiple videos and guest interviews, he frames NAD as essential for mitochondrial energy production, DNA r...
Important Notes
NMN is currently restricted as a commercial supplement due to FDA rulings classifying it as an investigational new drug. NR remains available. Exercise and fasting are proven to naturally boost NAD levels and should be prioritized over supplementation. There is no consensus among our 5 experts that supplementation is necessary or beneficial for healthy individuals.
Where Experts 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.
- 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.
