NAD+ Capsules | Nicotinamide Adenine Dinucleotide, Longevity Research
NAD+ (Nicotinamide Adenine Dinucleotide) is a fundamental coenzyme present in every living cell, serving as a hydride carrier in redox reactions and a substrate for sirtuins (SIRT1–7), PARP enzymes, and CD38. Cellular NAD+ levels decline significantly with age, making it a central target in longevity and metabolic research. These capsules (500mg per capsule, 60 capsules) provide a convenient oral format for sustained research protocols.
Mechanism of Action
- Sirtuin substrate, required cofactor for SIRT1/SIRT3/SIRT5 deacetylase activity; regulates mitochondrial biogenesis, DNA repair, and metabolic homeostasis
- PARP activation, fuels poly(ADP-ribose) polymerases involved in DNA damage repair and genomic stability
- Electron transport chain, transfers hydride equivalents through Complexes I and II, driving ATP synthesis
- CD38 inhibition research, studied alongside CD38 inhibitors to examine age-related NAD+ decline mechanisms
Research Areas
NAD+ capsules are used in ageing biology, mitochondrial dysfunction, metabolic disease, and cancer metabolism research. Commonly studied alongside MOTS-c (mitochondrial peptide), SS-31 (cardiolipin binding), and 5-Amino-1MQ (NNMT inhibition) for comprehensive NAD+ pathway research panels.
Independent Lab Verification
Rainbow Peptide works with independent, accredited third-party laboratories, including Vanguard Laboratory (ISO 17025:2017-accredited, A2LA Certificate #6377.01.01), to verify compound identity and purity. A Certificate of Analysis is included with every order.
For Research Use Only. Rainbow Peptide supplies this compound exclusively for in vitro and laboratory research purposes. Not for human or veterinary use.
Frequently Asked Questions
- What is NAD+ Capsules (500mg)?

- Is NAD+ Capsules (500mg) for sale at Rainbow Peptide?
- Yes. NAD+ Capsules (500mg) is available for purchase with Certificate of Analysis confirming >98% HPLC purity. Every order Overnight and 2–3 day delivery available. For Research Use Only.
- What purity is your NAD+ Capsules (500mg)?
- Rainbow Peptide's NAD+ Capsules (500mg) is >98% pure, HPLC verified through independent third-party laboratory testing, including work performed by Vanguard Laboratory (ISO 17025:2017-accredited, A2LA Certificate #6377.01.01). A COA is included with every order.
- What does the Certificate of Analysis actually verify?
- A COA reports identity (confirming the compound is what it's labeled as, via HPLC-UV/VIS matched against a reference standard) and assay/content (the measured purity percentage). Together, this verifies a batch matches its labeled specification, rather than relying on a purity claim alone.
- Is NAD+ Capsules (500mg) safe for human use?
- No. NAD+ Capsules (500mg) is strictly For Research Use Only (RUO). It is not intended for human consumption and is not intended to diagnose, treat, cure, or prevent any disease.
- How quickly does NAD+ Capsules (500mg) ship?
- Overnight and 2–3 day delivery available. Ships in temperature-controlled packaging.
