Where to Buy NAD+ for Research

What NAD+ is, in research terms

NAD+ — nicotinamide adenine dinucleotide — is a coenzyme found in every living cell. In energy metabolism it shuttles electrons, which is how cells turn fuel into usable energy. It is also consumed by families of enzymes that help maintain and repair DNA.

That second role is why NAD+ became central to aging research over the last two decades: published research has examined how cellular NAD+ levels change with age and what that means for those repair systems.

What to look for when you buy NAD+

• The amount on the label. NAD+ is sold in much larger quantities than most peptides, so check the milligrams.
• Sealed, dry powder. NAD+ is sensitive to moisture and light; it should arrive sealed and be stored cold.
• Documentation on request for the lot you received.
• A research-only seller. Research-grade NAD+ is a laboratory material, not a supplement.

How pricing works

NAD+ is priced per vial, and multi-vial packs lower the per-vial price on most of our products. Current pricing is live on the product card below.
