NAD+ Tablets → 500mg/Tablet

Buy NAD+ tablets from PSPeptides — each tablet delivers 500mg of nicotinamide adenine dinucleotide (NAD+) in a stable oral format built specifically for laboratory research. Every batch is manufactured in the US and verified at 99%+ purity through independent third-party testing, with results supplied on a batch-specific Certificate of Analysis. Researchers who buy NAD+ tablets from this listing receive a 30-tablet count suited to studies of cellular energy metabolism, sirtuin biology, and aging pathways.

What Is NAD+?

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every living cell, where it shuttles electrons during energy production and acts as a required substrate for sirtuin and PARP enzymes. Cellular NAD+ concentrations decline steadily with age, a pattern that has made NAD+ restoration a central focus of metabolic and longevity research.

Many labs that buy NAD+ tablets do so to standardize an oral dosing arm alongside precursor compounds like NR or NMN. Researchers exploring this pathway often start with our longevity research guide for background on related compounds and study designs.

Outside of aging biology, NAD+ also plays a supporting role in redox balance for research into oxidative stress, mitochondrial dysfunction, and cellular senescence, making it a compound of interest across several adjacent research fields rather than a single narrow niche.

Key Research Applications

• Cellular Energy Metabolism: NAD+ is a required cofactor in mitochondrial ATP production, making it a common variable in bioenergetics studies.
• Sirtuin Activation Studies: NAD+ availability directly limits SIRT1-7 enzyme activity, a pathway of ongoing interest in aging research.
• DNA Repair Research: PARP enzymes consume NAD+ while repairing damaged DNA, linking this coenzyme to genomic stability studies.
• Comparative Format Studies: Researchers who buy NAD+ tablets often use them as a standardized oral reference point against NMN, NR, and injectable NAD+ protocols.
• Circadian and Metabolic Signaling: NAD+ fluctuates with feeding and activity cycles, making it a variable of interest in chronobiology research.
