5 things every man over 40 should know about NAD+
A no-hype briefing on the molecule behind energy, focus, and healthy aging — and how to actually raise it.
NAD+ is having a moment for good reason — it sits at the center of how your cells make energy and repair themselves. Here's what actually matters, minus the marketing.
NAD+ falls fast after 40
Levels can drop up to 50% by age 60. That decline lines up with lower energy, slower recovery, and foggier focus.
NMN is the most-studied way to restore it
NMN is a direct precursor to NAD+. Supplementing it is the best-researched route to raising cellular NAD+.
Dose is everything
Research uses around 500mg. Many products underdose at 100–250mg. Check the label for the real number.
Purity and testing matter
Look for ≥99% purity and a third-party Certificate of Analysis — not just a claim on the bottle.
Clean formulation beats mega-blends
Skip proprietary blends and underdosing. A clinically-dosed 500mg NMN at 99.9% purity — fully disclosed — covers the essentials.
Bottom line: a clinical 500mg dose, verified purity, and a COA in the box are the three things worth insisting on.
