How Much Does NAD+ Cost? Bulk & Gram Prices

Research-grade NAD+ (β-Nicotinamide adenine dinucleotide, CAS 53-84-9 free acid / 1184-16-3 disodium salt) typically runs $0.35 to $2.10 per 100 mg in bulk kilogram quantities, $18 to $55 per gram in 5–25 g research packs, and $28 to $95 per vial for lyophilized 500 mg and 1000 mg single-lot units with a batch-specific certificate of analysis. Analytical-grade material from a major catalog house (Sigma-Aldrich, TCI, Cayman) sits far higher — $65 to $310 per gram, and up to $400+ per gram for enzymatically-assayed grades sold in 10 mg and 25 mg ampoules. The spread is not arbitrary. It tracks documentation depth, salt form, water content, and who paid for the testing.

What NAD+ Actually Costs, Broken Down by Format

Pricing splits into four tiers, and buyers routinely compare across tiers without realizing it:

Bulk API from a manufacturer: $350–$2,100 per kilogram, 25 kg minimum order quantity common, 4–8 week lead time, ex-works pricing that excludes freight and customs. A manufacturer's in-house COA accompanies the lot.
Repackaged bulk, 5–100 g: $18–$55 per gram. Sourced from the same drums as the tier above, subdivided under variable environmental control.
Lyophilized single-lot vials, 500–1000 mg: $28–$95 each. Prices below roughly $22 per gram of contained material generally signal that no independent third-party assay was paid for on that specific lot.
Analytical reference standard: $65–$400+ per gram, sold in 10 mg to 1 g units, with a full identity package and stated uncertainty on the assay value.

A researcher buying a reference standard to calibrate an instrument and a researcher buying working material for an assay development program have genuinely different requirements, and paying reference-standard prices for working material is a common and expensive mistake — a 50-fold price gap for a specification difference that often amounts to 98.5% versus 99.2%.

The Salt Form Nobody Adjusts For

NAD+ free acid has a molecular weight of 663.43 g/mol. The disodium salt is 707.40 g/mol. Buying disodium salt means roughly 6.2% of the mass is sodium, not NAD+. Suppliers are not obligated to normalize the price, and most do not. Two listings at $40 per gram are not the same purchase if one is free acid and the other is disodium; the effective cost per mole differs by about 6.6%.

Water content compounds this. NAD+ is hygroscopic. Karl Fischer titration on lyophilized lots commonly returns 2% to 8% water, and a lot at 7% water sold as "99% pure by HPLC" contains meaningfully less NAD+ than the label arithmetic suggests, because HPLC area percent is typically reported on an anhydrous basis while the vial is weighed as-is. A $45 vial at 7% residual moisture has an effective cost of about $48.40 per gram of contained anhydrous material.

Area percent at 260 nm reports the fraction of UV-absorbing material that eluted. Residual solvent, sodium, water, and inorganic salts do not absorb at 260 nm. A 99.5% area-percent chromatogram is fully compatible with a lot that is 92% NAD+ by mass.

That distinction — area percent versus assay against a certified reference standard — is the single largest source of price confusion in this category, and it is rarely stated on a product page. Assay-by-quantitation costs the supplier more because it requires a purchased reference standard ($180–$600 per gram, consumed over a limited number of injections) and a validated calibration curve. Area-percent purity requires only a sample injection and integration.

The Cost Line Nobody Prices: The Certificate of Analysis

Third-party analytical testing is a real, itemizable expense, and its presence or absence explains most of the price gap between two visually identical products:

HPLC purity, single method, third-party lab: $85–$250 per lot
LC-MS or HRMS identity confirmation: $150–$400 per lot
Karl Fischer water content: $45–$120 per lot
Residual solvent by GC headspace: $180–$350 per lot
Heavy metals panel by ICP-MS: $150–$300 per lot
Bacterial endotoxin (LAL): $95–$225 per lot

A full package runs $700 to $1,600 per lot. Amortized across a 500-vial lot, that is $1.40 to $3.20 per vial — trivial. Amortized across a 40-vial specialty lot, it is $17.50 to $40.00 per vial, which is why small-batch and low-volume materials carry disproportionate documentation premiums. A supplier that sells 40 vials of a niche compound and still provides a full third-party package is absorbing a cost that a high-volume seller barely notices.

The failure mode to watch for: a COA that carries a lot number not printed on the vial, or a COA dated more than 24 months before the ship date. Both make batch traceability unverifiable, which defeats the purpose of paying for documentation at all. Our approach to lot-level documentation is described on the quality page.

Cold Chain, Storage, and the Cost of a Ruined Lot

NAD+ degrades to nicotinamide and ADP-ribose. Degradation accelerates with heat, moisture, and alkaline conditions. Storage and handling costs are frequently omitted from purchase comparisons and frequently exceed the price difference between suppliers:

Lyophilized NAD+ at −20 °C: commonly specified stability of 24 to 36 months
Lyophilized at 2–8 °C: typically 6 to 12 months
Ambient storage at 25 °C: measurable assay loss within weeks, not months
Solutions in aqueous buffer: stability measured in days at 4 °C, and repeated freeze-thaw cycles produce stepwise assay loss

Cold-chain shipping adds $35 to $95 per domestic shipment for gel packs and insulated packaging, and $120 to $300+ for dry ice with hazmat documentation. A supplier quoting $32 per vial with $95 cold-chain freight on a two-vial order costs more than a supplier at $58 per vial with freight included. Shipping and handling terms are detailed on the shipping page.

The economic point: a $400 material loss from an ambient-shipped lot arriving after a weekend in a warehouse dwarfs the $60 saved on the purchase order.

Wholesale Economics and Where the Breakpoints Sit

Volume pricing on NAD+ is genuinely steep because the fixed costs — lot testing, lyophilization run setup, documentation — are spread rather than repeated. Observed breakpoint structure:

1–4 units: list price
5–9 units: 8–12% off
10–24 units: 15–22% off
25–99 units: 25–35% off
100+ units, single lot: 40–55% off, often with a single shared lot number and one COA

The 100+ tier carries a hidden liability. One lot number across an entire order means one point of failure. If that lot fails an incoming-inspection assay, the entire purchase is affected, not one vial. Multi-lot orders cost more per unit and are the more defensible choice for programs where continuity matters. Volume terms are outlined on the wholesale page.

When Buying NAD+ Isn't Worth It

This section is the one that costs sales, and it should be read before the price table.

If a validated, traceable reference standard is required, do not buy research-grade material at $40 per gram. Research-grade lots do not carry stated assay uncertainty, are not certified against a pharmacopeial standard, and cannot substitute for a USP or EP reference standard in a method-validation context. Spend the $180–$600 per gram or the resulting data is not defensible.
If the project needs NADH, NADP+, or NMN, NAD+ is the wrong purchase. These are distinct compounds with distinct CAS numbers and distinct prices ($95–$450 per gram for NADH). Substitution because of similar names is a recurring and completely avoidable loss.
If there is no −20 °C freezer available, the purchase will lose value before it is consumed. Buying 10 g to capture a 30% volume discount and storing it at room temperature is worse economics than buying 1 g four times.
If the required quantity is under 100 mg, catalog houses are usually cheaper on a total-landed basis. A 25 mg ampoule at $48 beats a 1 g vial at $55 plus $85 freight when 975 mg will sit unused until it degrades.
If the buyer cannot read a chromatogram, a COA provides limited protection. A COA is a document, not a guarantee, and a supplier-generated COA with no third-party laboratory name, no instrument identification, and no analyst signature is worth approximately nothing. Skepticism about supplier documentation generally is covered in quality research chemicals suppliers.
If the purchase is intended for any use in humans or animals, this material is not appropriate and should not be purchased. These are reference materials sold for laboratory research use only. See research use only.

A Cost Checklist Before Ordering

Before comparing two prices, normalize them. Confirm salt form (free acid or disodium), confirm water content from the Karl Fischer result, confirm whether purity is area percent or quantitative assay, confirm the lot number on the COA matches the vial label, confirm storage temperature and the stated shelf life from date of manufacture rather than date of shipment, and add freight and cold-chain cost to the unit price. Two listings 15% apart on the shelf price frequently invert once those six adjustments are applied.

The honest summary: for most laboratory work, $28–$95 per gram-scale vial with a lot-matched third-party HPLC and MS package is the correct band. Below $22 per gram, the testing was probably not performed on that lot. Above $150 per gram, a reference-standard specification is being paid for, and it is only worth the premium if the method requires it.
