Question 1

Is NAD+ a peptide?

Accepted Answer

No. It is a dinucleotide cofactor, chemically unrelated to the peptides in this catalogue.

Question 2

What is the difference between its two roles?

Accepted Answer

In metabolism it is recycled between NAD+ and NADH. Sirtuins, PARPs and CD38 instead cleave it, so those reactions consume it.

Question 3

Why are precursors used instead?

Accepted Answer

The dinucleotide is charged and crosses plasma membranes poorly, so nicotinamide riboside and NMN are the usual route in animal and human studies.

Question 4

How should it be stored in solution?

Accepted Answer

It hydrolyses in neutral and alkaline conditions, so solutions should be prepared fresh and kept cold rather than stored.

Question 5

Is intravenous NAD+ an approved treatment?

Accepted Answer

No. It is offered by some clinics without an approved indication, and the supporting trial evidence for that use is absent.

Question 6

What documentation comes with it?

Accepted Answer

A batch certificate of analysis with HPLC purity, linked on this page and verifiable on the testing laboratory's site.
