What NAD+ is
NAD+ is a vital coenzyme found in every cell that plays crucial roles in energy production, DNA repair, and cellular metabolism. Levels naturally decline with age, and supplementation supports cellular health and longevity. Common synonyms in the literature include Nicotinamide Adenine Dinucleotide, NAD, and Coenzyme I.
What it's studied for
Investigation of NAD+ to date is clinical-investigational, with the majority of citations concentrated in animal models and in-vitro assays rather than randomized controlled human trials. Published work referencing NAD+ spans Essential coenzyme for cellular energy production, Activates sirtuins for DNA repair and longevity, and Declines 10-50% with age across all tissues. Proposed mechanisms in the literature include Cofactor for NAD+-dependent enzymes including sirtuins and Essential for glycolysis and oxidative phosphorylation. None of this material describes therapeutic outcomes in humans, and BioInfinity does not sell, market, or provide dosing guidance for NAD+ outside laboratory research.
Laboratory handling — storage and reconstitution
Lyophilized NAD+ arrives as a fluffy off-white solid inside a sealed sterile vial. Because it ships as a small-molecule research compound, the powder is best stored between 2–8 °C prior to reconstitution and returned to −20 °C in aliquots for long-term storage post-reconstitution. Reconstitution is typically performed with bacteriostatic water (0.9 % benzyl alcohol preserved) rather than sterile water because the preservative extends solution stability once the vial has been punctured. Warming the reconstituted solution to room temperature before drawing helps redissolve any peptide that has settled against the vial wall. Avoid repeated freeze–thaw cycles: for peptides in this molecular-weight range, freeze–thaw stress is one of the most common causes of loss-of-purity between batches.
How this batch is verified
Every batch of NAD+ ships with a batch-specific Certificate of Analysis produced by an ISO-accredited third-party analytical laboratory. Reversed-phase HPLC confirms the assay against the expected the target molecular weight Da mass; mass spectrometry validates the exact monoisotopic mass; endotoxin (LAL) testing confirms bacterial-contamination limits appropriate for laboratory research; and residual-solvent panels confirm the manufacturing pipeline. The lot number on the outer label matches the COA on the public /coa-library page — every purity claim is independently verifiable before you open the vial.
