NAD+ Supplements: NMN vs NR, Evidence and Risks
A cautious look at NAD+, NMN, and NR supplements after 45 — what studies suggest, what remains uncertain, and what to discuss with a clinician.
Supplements & Biohacking
The supplement industry is flooded with anti-aging claims, making it difficult to know what has genuine scientific support. Our guides focus on specific compounds that have been studied in the context of healthy aging, while clearly explaining the current state of the evidence and its limitations.
We review what is known about popular longevity supplements like NAD+ boosters (NMN and NR), and we are consistently cautious about overclaiming. Supplements, where appropriate, should only ever complement a solid foundation of nutrition, sleep, and exercise — not replace it.
Not medical advice. Do not start any new supplement regimen without consulting your clinician, especially if you take medications or have existing health conditions.
