NAD+ Supplements: The 2026 Longevity Science

If you spend any time in longevity circles — Rhonda Patrick, Peter Attia, David Sinclair — you've heard about NAD+. NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every cell, involved in over 500 enzymatic reactions: energy production, DNA repair, cell signaling, and activation of sirtuins (longevity proteins).

Here's the problem: NAD+ levels drop roughly 50% between your 20s and 50s. And that decline correlates with virtually every major hallmark of aging.

The Human Evidence in 2026

• NMN and NR supplementation reliably raises blood NAD+ levels in humans
• Improved muscle function and energy in older adults
• Better insulin sensitivity and metabolic markers
• Cognitive support signals in early trials

The Practical Approach

• NiaCel 400 by Thorne (NR) — 400mg nicotinamide riboside per serving, the most clinically studied NAD+ precursor. Clinically proven to raise NAD+ levels.
• ResveraCel by Thorne (NR + Resveratrol) — combines NR with resveratrol to activate SIRT1 and amplify NAD+ pathway benefits in one capsule.
• Liposomal NAD+ Ultra by VitaScripts — liposomal delivery for dramatically enhanced absorption and cellular uptake.
• Basic B Complex by Thorne — high-dose NAD+ precursors consume methyl groups. Always stack with active methylated B vitamins.
