What NAD+ is

NAD+ (nicotinamide adenine dinucleotide) is not a peptide — it's a coenzyme, a helper molecule that every cell uses to produce energy. It is supplied as an analytical-grade reference material for laboratory research.

What it does — in plain terms

NAD+ works like a rechargeable battery your cells pass around to get chemical work done, especially turning food into usable energy. Levels naturally decline as we age, which is why it's a huge topic in aging research. Labs study how NAD+ powers energy production, helps repair DNA, and switches on a family of 'maintenance' proteins called sirtuins that are linked to healthy aging.

Here's where NAD+ actually shows up in the published research:

Cellular energy production
DNA repair
Sirtuin ('longevity gene') activity
Aging and metabolism models

Plain-language explanations describe what researchers study — not what any product does for a person, and not medical advice. Every material here is sold for laboratory research use only and is not for human or animal use.

Reconstitution reference

Standard laboratory reconstitution volumes for NAD+, from the VNG Reconstitution Sheet. See the full reconstitution guide for the method and concentration math.

Product	Vial	Bacteriostatic water	Resulting concentration
NAD+	500 mg	2.5 mL	200 mg/mL
NAD+	1000 mg	5 mL	200 mg/mL

Published research

A selection of peer-reviewed and clinical literature indexed on PubMed. Provided so qualified researchers can locate the primary sources — inclusion here is not a claim about any product or outcome.
