NAD+
Nicotinamide adenine dinucleotide — redox cofactor reference standard
How researchers describe NAD+
NAD+ is an obligate redox cofactor (the NAD+/NADH couple) and the consumed substrate of NAD+-dependent enzymes: sirtuins (SIRT1–7 deacylases), PARPs (DNA-repair signaling), and CD38. Preclinical literature examines cellular NAD+ availability in relation to mitochondrial oxidative phosphorylation, SIRT1/SIRT3 activity, genome maintenance, and the documented decline of tissue NAD+ pools with age.
- Sirtuin (SIRT1/SIRT3) NAD+-dependent deacylation
- PARP / DNA-damage repair signaling
- Mitochondrial redox (NAD+/NADH, OXPHOS)
- CD38 / NAD+ salvage flux
Lyophilized: −20°C, desiccated and light-protected. Reconstitution and stability are set by the end researcher; no use-window or dosing guidance is provided.

Common researcher questions
Is this for human use?+
No. All X Factor research materials are RUO — sold solely for in-vitro and non-clinical preclinical research. Not for human or veterinary use, food, supplement, cosmetic, or therapeutic application.
How is purity verified?+
Every lot ships with the supplier’s per-lot COA (HPLC purity). COA available per lot — request via contact form.
How is it shipped?+
Lyophilized reference standard in a sealed glass vial, packed in plain outer packaging, shipped from our US fulfillment partner. Cold-pack on request.
Can I get a COA before ordering?+
Yes — contact us with the SKU and we will email the most recent lot COA. We also publish the COA vault to verified researchers post-purchase.
Restock for OOS items?+
Use the Notify-Me form on the catalog page. We email when the lot is QC-passed and live. No spam, single-use.
