High Purity 99% NAD+ Powder CAS 53-84-9 Nicotinamide Adenine Dinucleotide Supplement

So you're looking at the 99% NAD+ powder, and the first thing most buyers ask is about the actual purity verification, and we've got that covered with an HPLC certificate —usually runs about 663.43 g/mol molecular weight, and we include the full COA with the shipment.

The white crystalline powder dissolves cleanly in water, which matters for your reconstitution protocols, and we've seen some folks try to push it beyond 48 hours at room temp, but honestly, you'll want to keep it at -20°C in a dry enviroment for the full 24-month shelf life.

What we do differently is we retest any batch that's been sitting in our warhouse for six months or so, just to be sure teh purity hasn't drifted—it's a small thing, but it saves headaches later when you're running sensitive assays.

Actually, we've had buyers ask if this works for oral supplementation, and no, it's strictly for biochemical research—you don't want to be ingesting high-purity crystalline form meant for lab work.

Each batch gets unique lot number, we keep the TDS and SDS on file, and if you need a retest after six months of storage, we can do that for a nominal fee, but in most cases, the powder holds steady if stored properly.

Lead time is typically 10-14 business days for orders up to 100 grams, and our company can do smaller quantities if you're just starting a new protocol—just let us know your preferred packaging size when you send the PO.
