NAD (nicotinamide adenine dinucleotide) is a coenzyme present in every living cell, central to redox reactions, mitochondrial function, and cellular metabolism. It appears throughout the peer reviewed literature on cellular energy production, sirtuin activity, and metabolic aging pathways, which is why it is one of the more frequently requested compounds among laboratories working in cellular biology and metabolism research.
For researchers already familiar with NAD's role in the literature, the operative question when selecting a supplier isn't what it does. It's whether the material received actually matches what's on the label. That's a sourcing and documentation problem, and it's the one this guide addresses.
NAD is a well characterized molecule, but synthesis and handling quality vary significantly across suppliers, and degradation products can compromise research data before an experiment even begins. Two things matter most when qualifying a source:
Identity confirmation: mass spectrometry (MS) and/or HPLC data confirming the material matches the expected molecular structure, not just the label on the vial.
Purity quantification: a stated purity percentage backed by chromatographic data, not just a claim.
Without both, there is no way to know whether a batch is research grade or whether it introduces confounding variables into downstream results.
A Certificate of Analysis (COA) is the documentation that ties a specific batch to its test results. Before treating any COA as sufficient, check that it includes:
Batch or lot number matching the product received Third-party (not just in-house) testing HPLC purity percentage Mass spectrometry identity confirmation Test date and testing laboratory name
A COA that's generic, undated, or not tied to a specific batch number isn't a meaningful verification. It's marketing collateral.
Nordiscience sources NAD under GMP-following manufacturing protocols and independently verifies each batch through third-party lab testing. A Certificate of Analysis is available on request for every batch sold, including HPLC purity data and mass spectrometry identity confirmation, so researchers can verify what they are receiving before it reaches the bench.
Beyond the compound itself, Nordiscience is built around the practical friction points that slow down research procurement: standard credit card, Apple Pay, and Google Pay checkout (no crypto-only paywalls), fast US shipping, and a support team reachable by email or WhatsApp for sourcing or documentation questions.
Request a Certificate of Analysis for any current batch, or reach out with sourcing questions, at info@nordiscience.com or via WhatsApp (Mon to Fri, 9 AM to 5 PM Mountain Time).
