● NAD+Longevity coenzyme

NAD+ price comparison

NAD+ (nicotinamide adenine dinucleotide) is a naturally occurring coenzyme found in all living cells, where it participates in redox reactions and serves as a substrate for enzymes involved in cellular energy metabolism and signaling. In research settings it is studied for its roles in mitochondrial function, DNA repair pathways, and cellular aging in laboratory models. This index tracks research-use-only vendor pricing for NAD+ so researchers can compare cost across suppliers.

▸ Why compare $/mg for NAD+?

Per-mg NAD+ prices vary because vendors differ in source material, stated purity, lot testing, and vial sizes, and because NAD+ is often sold in a wide range of quantities that change the effective unit cost. Comparing normalized $/mg across suppliers helps a researcher separate genuine value from packaging differences and identify outliers in either direction.

▸ Reading the COA

For NAD+, confirm identity on the COA by mass spectrometry against the expected molecular weight (~663.4 Da for the free acid) and check HPLC purity, ideally 98%+ for research-grade material. Because NAD+ readily degrades, watch for elevated levels of common breakdown products such as nicotinamide and ADP-ribose, which indicate hydrolysis; a reputable COA reports these as named impurities rather than a single lumped figure.

▸ FAQ

How is lyophilized NAD+ typically stored as a research material?

Lyophilized NAD+ is generally kept sealed and desiccated at low temperature (commonly -20°C or colder) and protected from light and moisture, since the compound is hygroscopic and prone to hydrolytic degradation. Vendors typically specify storage conditions on the label or COA; once reconstituted it is far less stable than the dry powder, so most protocols treat solutions as short-lived. This is general storage information for research material, not use guidance.

What is a COA and what should I check for on one for NAD+?

A Certificate of Analysis (COA) is a lot-specific document from the manufacturer reporting analytical test results for the material you receive. For NAD+, check that identity is confirmed by mass spectrometry against the expected molecular weight, that HPLC purity meets the stated threshold, and that degradation-related impurities like nicotinamide are quantified. A COA verifies what the material is, not any outcome from using it.

Why do per-mg NAD+ prices differ so much between vendors?

Differences reflect stated purity grade, extent of lot testing (full HPLC and MS panels cost more), quantity per vial, and vendor overhead and margin. Larger vials usually lower the per-mg cost, while small research quantities carry a premium. Normalizing to $/mg makes these factors comparable across suppliers so pricing outliers are easier to spot.
