NAD+ (500mg) is a high-content vial intended for laboratories investigating cellular energy metabolism, mitochondrial function, and redox biology. This oxidized nicotinamide adenine dinucleotide form is widely used in assays exploring sirtuin activity, DNA repair, and age-related cell signaling. Our NAD+ is prepared as research-grade material, US lab tested, and accompanied by a Certificate of Analysis so you can verify assay-relevant purity. 

The 500mg format is ideal for groups running repeated in vitro experiments, creating multiple working stocks, or supporting parallel projects. For larger consumption needs, a higher-mass NAD+ vial is also available from the same quality-controlled supply line. Proper storage and careful reconstitution help maintain stability across study timelines. All NAD+ products from Health and Science Peptides are supplied strictly for research use only, not for human or veterinary use.
