Sourcing NAD+ for laboratory research comes down to one thing: can you verify what's in the vial? NAD+ is a coenzyme studied in cellular-energy and mitochondrial research. This guide covers what qualified researchers evaluate before buying, and where to find documented material.
What to evaluate when buying NAD+
- Measured purity — a real value (e.g. ≥98% by HPLC) with the method named, not a bare claim. See HPLC purity analysis.
- Batch-specific COA — analytical documentation tied to your exact lot. See how to read a COA.
- Independent / third-party testing — verification that isn't just an internal claim. See third-party testing explained.
- Defined identity — molecular formula C21H27N7O14P2 and sequence where applicable.
- Research-use-only labeling and honest storage guidance.
- Reliable, discreet, temperature-appropriate shipping.
