Cheapest NAD+ Prices UK

About NAD+

NAD+ is a coenzyme rather than a peptide, central to redox reactions and to the sirtuin and PARP enzyme families, and it appears here because researchers buying peptides routinely buy it alongside them. The literature is large and genuinely established at the biochemical level; what remains contested is whether exogenous administration meaningfully raises intracellular levels in humans, and over what timescale.

It is sold in much larger vials than any peptide on this site, typically 500mg, and it is notably hygroscopic and unstable once reconstituted. Storage and packaging matter more here than almost anywhere else in the catalogue, and a supplier's handling standards show up in material condition on arrival rather than in the certificate.

What moves the NAD+ price

Raw material cost per gram is low relative to peptides, so price differences reflect vial size, purity grade, packaging quality and shipping far more than synthesis. Larger vials look expensive in absolute terms and are usually the better per-milligram value. Suppliers that ship with desiccant and proper cold-chain protection cost more and are worth it for a compound this moisture-sensitive.

How we independently rank every supplier

This table is ordered by our own independent score, not by sponsorship. The score out of ten draws on published third-party analysis, verified company identity, moderated reviews collected through CheckALab, and operational data covering dispatch speed, stock accuracy and how the supplier handles problems.

For NAD+ we place unusual weight on packaging and delivery-condition reports from moderated reviews, because degradation in transit is the most common complaint and it is invisible on a certificate. Analytical documentation still counts, but arrival condition is the discriminating factor. Reviews influence scores only after moderation, and the blend is slow by design. We recalculate as evidence accumulates, so consistent handling failures pull a supplier down over time.

How to buy NAD+ cheaply without cutting corners

The lowest headline price is rarely the best value. Compare price per mg rather than price per vial, check whether a batch-matched certificate of analysis is published, and factor in delivery. A cheap vial with no third-party testing behind it is not a saving.

Kensington Labs currently sits at the top of this table at £49 for a 500mg vial, and holds a CheckALab score of 9.43/10.
