What to Check When Your NAD+ Arrives
Not every irregularity on arrival is a defect, and not every compound is defective under the same conditions. Here is what actually matters when a NAD+ shipment arrives.
In plain English
Check the powder is loose and free-flowing rather than caked or clumped. Clumping in NAD+ means moisture has already been absorbed, which tells you both that degradation has started and that any weighing will be unreliable.
What NAD+ actually is
NAD+ is not a peptide, and that single fact governs everything about handling it. It is a coenzyme — think of it as a rechargeable battery that shuttles energy around inside cells. It is present in every living cell, was first identified in 1906, and almost every peptide habit is wrong for it.

Arrival inspection for NAD+
Check the powder is free-flowing and not caked or clumped. Clumping in NAD+ indicates moisture uptake, which for this compound means both degradation already underway and unreliable gravimetric measurement.
Storage on arrival
Documentation to check
Note the different detection wavelength: nucleotides are read at 260 nm, not the 214 nm used for peptide bonds. Free nicotinamide content is the most informative impurity figure, since it is the direct hydrolysis product. Water content matters more here than for any peptide, given how hygroscopic the material is.
What NAD+ is studied for
Sirtuins consume NAD+ as a co-substrate, which links cellular NAD+ availability directly to their activity.
Its canonical role as the central redox carrier of cellular respiration.
PARP enzymes consume NAD+ during DNA damage response, a heavily studied competing demand.
A major driver of current research interest: measured NAD+ levels fall with age across tissues in animal models.
