NAD+ 1000mg | Research Grade

NAD+ UK availability is one of the most common research queries we receive — this page covers everything you need before ordering, including mechanism, purity testing, and storage guidance.

What Is NAD+?

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every living cell, playing a central role in cellular energy metabolism and DNA repair pathways. Unlike the peptide compounds elsewhere in our catalogue, NAD+ is a small-molecule coenzyme, but it is studied within the same longevity and cellular-ageing research context as compounds like Epitalon, which is why we stock it alongside our Anti-Aging peptide range. ApexPure supplies NAD+ at 1000mg per vial, manufactured to research-grade specification for laboratory use only.

Research Applications

NAD+ levels are known to decline naturally with age, and this decline has made NAD+ a central subject in cellular-ageing and mitochondrial-function research literature. Research has explored NAD+’s role as a substrate for sirtuins — a family of proteins linked to cellular repair and longevity pathways — as well as its function in mitochondrial energy production and DNA repair enzyme activity. It is frequently studied in comparative research alongside NAD+ precursor compounds to examine differences in cellular uptake and metabolic pathway activation.

Background & Research History

Interest in NAD+ as a research subject grew significantly once its role in sirtuin activation was identified, connecting it directly to a broader body of longevity-science literature. Since then it has become one of the more frequently referenced coenzymes in ageing and mitochondrial-function research, often studied alongside other longevity-research peptides such as Epitalon within the same broader research programme.

Purity & Third-Party Testing

Every batch of NAD+ is independently verified by a third-party laboratory to a minimum of 99% purity, with a downloadable, batch-specific Certificate of Analysis available on this product listing. As with every ApexPure product, no batch is released for sale until it clears our independent testing threshold.

Reconstitution & Storage Guidelines

Store the lyophilised vial frozen at -18°C or below, protected from light and moisture. Once reconstituted with bacteriostatic water, refrigerate the solution at 2-8°C and use within your laboratory’s standard timeframe. NAD+ is a comparatively less stable molecule than many peptides once in solution, so minimising freeze-thaw cycling matters even more here than with more stable compounds in our catalogue.

Handling Notes for Researchers

NAD+ should be handled only by qualified laboratory personnel using appropriate PPE, following institutional protocols for reconstitution, storage, and disposal. This product is supplied strictly for laboratory research and is not intended for human or veterinary use.

Why Buy NAD+ UK From ApexPure

ApexPure was built around one standard: every batch we sell is independently tested before it reaches your laboratory, and every Certificate of Analysis is published, not hidden behind a support request. NAD+’s comparative instability once reconstituted makes independent, batch-specific testing especially important, and we hold it to the same rigorous HPLC standard as every other product in our range. Orders are dispatched from the UK, so researchers avoid the customs delays and cold-chain uncertainty that come with importing from overseas suppliers.

Frequently Asked Questions

Is NAD+ a peptide?
No — NAD+ is a coenzyme, not a peptide. It’s stocked in our Anti-Aging category because it’s studied within the same longevity and cellular-ageing research context as our peptide compounds.

What is NAD+ commonly studied alongside?
NAD+ is frequently studied alongside other longevity-research compounds, including Epitalon, within broader cellular-ageing research programmes.

Is NAD+ legal to purchase in the UK?
Yes, as an unlicensed research chemical sold strictly for laboratory and in-vitro research purposes. It is not licensed for human consumption or clinical use.

This product is sold strictly for laboratory and in-vitro research use only.
