Product Information
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.
