NAD+ + NMN
Also known as: NAD+ and NMN, NAD+ / NMN Combination, NAD Precursor Stack
Pairs NAD+ itself with NMN, its immediate biosynthetic precursor, on the rationale that supplying the precursor supports ongoing regeneration rather than a single transient rise.
Components
How it's combined
Research framing: NMN sits one enzymatic step from NAD+ in the salvage pathway, where nicotinamide phosphoribosyltransferase (NAMPT) is the rate-limiting enzyme and NMN adenylyltransferases convert NMN to NAD+. The rationale for pairing them is that NAD+ is a large, charged molecule that crosses cell membranes poorly and is substantially degraded extracellularly into precursors before uptake, so administering the precursor alongside it targets the intracellular pool more directly. Note the asymmetry in evidence: NMN has human pilot dosing studies behind it, while injectable NAD+ protocols rest largely on clinical practice and observational reports rather than controlled trials.
