NAD+ UK — buying guide

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in all living cells — and, unlike most of the catalogue, it is not a peptide. It is built from two nucleotides joined through their phosphate groups, one bearing adenine and the other nicotinamide, carries CAS number 53-84-9, and has a molecular weight of 663.43.

As a coenzyme, NAD+ is central to cellular energy metabolism and redox chemistry, and is a major focus of mitochondrial and cellular-ageing research, where investigators examine how cellular NAD+ levels relate to energy metabolism, sirtuin activity and ageing in model systems. Sova supplies it as a research-grade powder — not for human or veterinary use, and with no claim of any effect in people.

NAD+ is hygroscopic and degrades if poorly handled, so what matters when buying is a purity figure measured on the actual batch, documented on a certificate.

Every Sova NAD+ vial ships with a batch-linked Certificate of Analysis. Before you buy, confirm the CoA references the batch on the vial, that identity is confirmed against the expected 663.43 Da, and that purity is measured by reverse-phase HPLC. Enter the batch at /verify to pull the certificate.
