Best NAD supplements: compare labels, testing and cost

Choose the ingredient first. Compare price within the ingredient you intend to buy. Different salts, ingredients and serving amounts are not clinically equivalent. These are six sampled products, arranged alphabetically in the detailed table, rather than an exhaustive market ranking.

For the difference between the molecules and routes, read NMN versus NAD+. If you meant clinician-prescribed injections, use the separate NAD+ injection provider comparison.

Amounts below are the manufacturer's labeled serving, not our suggested dose. Prices are standard one-time advertised US product prices checked October 15, 2026. Shipping, tax and any checkout charges are outside the calculation. Subscription discounts and renewal terms are excluded from this table; selecting a recurring option changes the payment agreement.

ProHealth has the lowest advertised product price per labeled serving in this sample at $0.90, but a single $26.95 bottle falls below its advertised $30 free-shipping threshold. That is not a lowest-delivered-cost finding. Double Wood's availability is unresolved. A label serving also does not necessarily equal a day's supply.

A certification listing, a laboratory report and a brand's testing badge answer different questions. The Basis and NiaCel 400 NSF entries identify specific products and lots. Match your bottle to the relevant entry; the listing is not evidence that a supplement extends life.

ProHealth's linked Brighton report measures NMN potency in a client-supplied sample. Its scope does not establish a complete contaminants assessment. Renue publishes reports with different scopes for lot 072827561: the Colmaric report includes NAD potency, metals and microbes, while the separate Summit report measures four actives. The reports show different NAD assay results using different laboratories and methods. That is not a controlled comparison of stability or proof that potency declined. ProHealth report; Renue product and lot reports.

Double Wood's linked COA identifies in-house testing, even though its product page makes a broader third-party-testing claim. Tru Niagen's page displays a SuppCo badge; we did not retrieve the independent report. Read the testing claim together with that limitation. Ask for the report matching the lot you will receive, including the analytes you care about, rather than relying on a generic “tested” logo.

The studies reviewed here do not identify a best NAD supplement for women. A small randomized study tested oral NMN, 250 mg daily for 10 weeks, in 25 postmenopausal women with prediabetes and overweight or obesity. It found improved skeletal-muscle insulin sensitivity. It did not establish treatment for hot flashes, weight loss or benefits for women generally. Yoshino et al., 2021; NIDDK's study summary.

That NMN regimen is not evidence for an NR product, direct NAD+ capsule or injection, or for every current NMN bottle. A product marketed to women still needs an exact label and relevant human evidence. If your decision concerns menopause symptoms and hormone care, HRT Picks compares menopause HRT services; NAD-related supplements are a separate category.

Blood NAD measurements, metabolic tests and felt benefits are different outcomes. The table preserves the studied ingredient, population and duration. Trial amounts describe research; they are not instructions to copy a regimen.

Ingredient research does not validate every finished formula. Neither NR chloride trial establishes an equivalent effect for Thorne's hydrogen-malate salt or Renue's four-ingredient liposomal blend. We did not verify a finished-product trial for the current Double Wood, ProHealth, Renue or Thorne products. These selected trials also do not establish long-term safety across populations.

FDA does not approve dietary supplements before they are marketed. A supplement label, certification or testing report should not be read as FDA approval of a drug or proof that a product treats a disease. FDA: questions and answers on dietary supplements.

1. Match the exact ingredient and salt on the label. Avoid treating the total milligrams in a blend as one equivalent NAD dose.
2. Match the bottle's lot to the certificate or laboratory report. Check what was actually measured and who supplied the sample.
3. Check the first payment, delivery interval, renewal amount and cancellation deadline if you select a subscription. A prepaid amount divided by months is not a monthly bill.
4. Confirm current stock, shipping and tax before comparing delivered cost. The product prices above are source observations, not checkout guarantees.
5. Read the product's warnings. Discuss suitability with a qualified clinician if you are pregnant, nursing, taking medicines or managing a medical condition. Elysium's current Basis page says not to use it while pregnant or nursing; Thorne's product page has its own warnings.

Basis label and warnings; NiaCel 400 ingredients and warnings. For a deeper ingredient decision, continue to NMN versus NAD+: molecules, routes and evidence. Keep injection prices and clinical assessment in the separate injection-care guide.

Educational product comparison, not medical advice or a personalized supplement recommendation. We compare public labels, reports and studies, and have not tested these products or assessed individual suitability. Our comparison methodology.
