NAD+ Research Guide: The Metabolic Coenzyme

NAD+ (nicotinamide adenine dinucleotide) is not a peptide at all — it is a coenzyme present in every living cell, central to redox metabolism, and one of the most-studied molecules in contemporary ageing research.

Why researchers care

NAD+ shuttles electrons in cellular respiration and serves as substrate for sirtuins and PARPs — enzyme families tied in the literature to DNA repair and metabolic regulation. Documented age-related NAD+ decline is a cornerstone observation of geroscience, driving enormous research interest in restoration approaches.

In-vitro applications

Cell-culture studies manipulating NAD+ availability, sirtuin-activity assays and mitochondrial-function work are the standard applications. It pairs naturally with MOTS-c and epithalon in longevity-focused research programs — see our longevity category.

Handling

NAD+ is supplied lyophilised and is hygroscopic — reseal quickly, store cold and dark. We stock 100mg and 500mg vials with batch documentation available on request, dispatched express Australia-wide.

If you run a peptide business, or are building one, we wholesale Australian-sourced stock to trade buyers across Australia.

All compounds discussed are for in-vitro laboratory research only and are not for human or veterinary use.
