NAD+ Peptide Liquid Spray (1000mg) for Laboratory Research

NAD+ stands for nicotinamide adenine dinucleotide. It is a coenzyme found in every living cell, and one of the most studied molecules in biochemistry.

Its primary role is electron transfer. NAD+ cycles between an oxidized form (NAD+) and a reduced form (NADH), picking up electrons in one reaction and delivering them in another. That shuttling is what allows glycolysis, the citric acid cycle, and oxidative phosphorylation to proceed — which is why NAD+ appears in essentially every metabolic pathway diagram.

What made NAD+ a subject of intense research over the past two decades is a second role that works differently. Three enzyme families — sirtuins, PARPs, and CD38 — use NAD+ as a consumable substrate rather than a recyclable carrier. They break the molecule apart to do their work. That means these enzymes compete for a finite cellular pool, and it means NAD+ availability becomes a variable in gene regulation, DNA repair, and immune signaling research rather than a constant that can be assumed.

Real Peptides supplies NAD+ pre-solubilized at 1000mg for laboratory research use.

NAD+ appears across an unusually wide span of published literature because it sits at the intersection of two distinct biological roles.

As a redox carrier, it is fundamental to bioenergetics research — any study of cellular bioenergetics involves it. As an enzyme substrate, it is central to work on sirtuins, DNA damage response, and senescence-associated pathways, where the question is not what NAD+ does but how much of it is available and what is consuming it.

That second area is where most current research attention sits. Because sirtuins, PARPs, and CD38 all draw from the same pool, changes in one pathway affect the others — a competition dynamic that makes NAD+ availability a meaningful experimental variable rather than background.

The pre-solubilized format supports consistent concentration control across replicates by removing the reconstitution step.

For Research Use Only.

NAD+ is hygroscopic and degrades in solution more readily than many research compounds, which makes handling a real variable in experimental consistency. Every reconstitution introduces an opportunity for concentration error and for exposure to moisture and light.

Supplying it pre-solubilized removes that step. At 1000mg in a multi-use dispenser, the material is prepared once under controlled conditions rather than repeatedly at the bench.

Real Peptides also supplies NAD+ as lyophilized powder in vial format for study designs requiring custom solution concentrations.
