NAD+ is among the most extensively studied coenzymes in cellular biology. Research has documented its roles in mitochondrial energy production, the NAD+/NADH redox ratio, sirtuin activation (SIRT1-SIRT7), PARP DNA repair mechanisms, and calcium signaling via CD38. A substantial body of research has examined NAD+/NADH ratio dynamics in cell and animal models, and the downstream effects on mitochondrial function and DNA repair capacity. It is a core tool in mitochondrial research, cellular signaling, and redox biology laboratories.
This compound is supplied strictly for research purposes. No clinical or therapeutic application is implied or represented.

Handling Information
Handle NAD+ under standard laboratory conditions. It is sensitive to repeated freeze-thaw cycles and should be aliquoted after reconstitution to minimize degradation. Protect from light and heat. This compound is intended for qualified research use only.
Storage Requirements
- Long-term (lyophilized): Store at -20°C, protected from light and moisture
- Short-term (reconstituted): Store at 4°C; use within 7 days; aliquot to avoid repeated thaw
- Keep in original sealed vial until point of use

5th vial of this lot line — same appearance and documentation every time. Heartland is consistent.
How should I store this peptide?+
Lyophilized peptides should be stored at −20°C in a dry, light-protected environment. Avoid repeated freeze-thaw cycles. Once reconstituted, store at 2-8°C and use within 4-8 weeks depending on the compound.
What should I reconstitute it with?+
Bacteriostatic water or sterile water for research use. We recommend our companion BAC Water for consistency. Specific reconstitution volume depends on your research protocol — refer to the Specifications tab for solubility data.
How quickly do orders ship?+
Orders confirmed before 2:00 PM CT ship the same business day from our facility in Tulsa, OK. Standard US transit is 2-5 business days. Tracking provided at shipment.
Is the COA verified independently?+
Yes. Every lot is tested by HPLC for purity (target ≥99%) and mass spectrometry for molecular identity before release. The COA is generated from the actual lot data, not a generic template.
Can I get bulk or institutional pricing?+
Yes — qualified research facilities and high-volume orders receive tiered pricing. Contact us with your institution information and target quantities.
