When people compare NMN and NR supplements, they typically look at the bottle price. NMN seems cheaper: a 100 g bag can run $55. NR capsules seem comparable: a 30-count bottle of the leading brand runs $49. On those numbers, NMN barely wins.
The cost-per-gram comparison tells a different story.
What NMN and NR Are
Both nicotinamide mononucleotide (NMN) and nicotinamide riboside (NR) are oral precursors to NAD+ (nicotinamide adenine dinucleotide), a coenzyme involved in cellular energy metabolism. The body converts each to NAD+ through different enzymatic steps. Neither is the same compound as NAD+ itself; neither is FDA-approved as a drug; both are sold as dietary supplements. The research base for each is growing but still limited, with most human trials small and short.
The distinction that matters for cost comparison: NMN is typically sold as a loose powder in gram quantities. NR is almost always sold as branded capsules in milligram servings. That packaging difference drives the price gap more than the underlying molecules do.
Cost Per Gram: Verified Numbers
The table below uses prices and doses verified from each brand's own product page. All three rows represent verified data as of 2026-09-09; three additional products in our database have prices pending browser verification and are listed separately.
| Product | Form | Dose per serving | Price paid | Price per gram of precursor |
|---|---|---|---|---|
| Renue By Science Pure NMN Powder, 100 g | NMN powder | Self-measured | $54.95 | $0.55/g |
| Tru Niagen 300 mg, 30 ct | NR capsule | 300 mg | $49.00 | $5.44/g |
| Elysium Basis, 30 servings | NR capsule | 250 mg NR | $65.00 | $8.67/g |
Sources: Renue By Science product page (verified 2026-09-09); Tru Niagen product page (verified 2026-09-09); Elysium Basis product page (verified 2026-09-09).
The range spans roughly 10× to 16×. That is not a rounding difference.
Three products not included: DoNotAge Pure NMN, Thorne NiaCel 400, and Life Extension NAD+ Cell Regenerator each have public product pages, but the prices either require a cart login (Life Extension), are rendered in JavaScript without a Product schema (Thorne), or are listed as "From" without specifying which size the base price applies to (DoNotAge). We do not include a price-per-gram figure for any of them until we can read the price-size pairing directly.
Why the Gap Is That Wide
1. Powder versus capsule manufacturing
A kilogram of pharmaceutical-grade NMN bulk powder costs the manufacturer less to produce per unit than the same quantity of NR in individual capsules. Capsule manufacturing adds fill, shell material, labor, and packaging cost to every serving. NMN powder avoids all of that.
2. NR brand positioning
Tru Niagen and Elysium are branded NR products backed by patent portfolios. ChromaDex holds patents on NR (the NIAGEN trademark) and licenses the ingredient to manufacturers including Tru Niagen. Elysium uses a licensed form of NR. Patent licensing costs appear in the finished goods price. Generic or off-patent NMN does not carry the same licensing overhead.
3. Different typical doses
Common study doses for NR range from 250 to 500 mg per day. Common NMN doses cited in human studies range from 250 mg to 1,200 mg. If someone takes 500 mg of NMN powder daily from the Renue By Science product, that works out to about $0.28 per day. If someone takes 300 mg of Tru Niagen, it works out to about $1.63 per day. The cost difference at typical doses is about 6× — not 10×, but still substantial.
4. Third-party testing status
None of the three products with verified prices currently have a published certificate of analysis in our database. Tru Niagen and Elysium are certified by NIAGEN licensing (ChromaDex performs quality testing on its ingredient), but batch-specific published COAs are not prominently linked from either product page. DoNotAge explicitly states third-party testing is "available upon request" rather than published — the distinction we track as claimed-unpublished rather than published. A branded capsule product is not automatically better tested than a powder; it is better marketed.
What the Numbers Do Not Tell You
Cost per gram is a purchasing efficiency metric. It does not tell you:
- Which form the body converts more readily. Published pharmacokinetic studies suggest both NR and NMN raise blood NAD+ levels; head-to-head human data comparing them directly at matched doses are limited.
- Whether a higher dose of cheaper NMN equals the effect of a lower dose of NR. The enzymatic conversion pathways differ.
- Whether self-measuring powder introduces dosing inconsistency versus a pre-filled capsule.
If your primary decision criterion is cost, powder NMN is materially cheaper per gram. If consistent dosing, convenience, or a branded supply chain matters more, a capsule product answers a different question.
Clinics That Offer IV NAD+
All of the above covers oral supplements. A separate product category — intravenous NAD+ administered through a telehealth clinic — is not the same thing as a supplement. IV NAD+ is a compounded drug, delivered by a licensed practitioner, and is subject to the compounding pharmacy regulations covered in our FDA enforcement article. The pharmacokinetics are different; the price is an order of magnitude higher; and the regulatory environment is in active flux in 2026.
Clinics in our ranking that offer NAD+ protocols include Pallas Health, Peter MD, and HealthRX, among others. Those pages discuss compounding sourcing and pricing separately from oral supplement comparisons.
Prices sourced directly from each brand's product page. Calculations: Renue By Science $54.95 ÷ 100 g = $0.55/g; Tru Niagen $49.00 ÷ (0.300 g × 30 servings) = $5.44/g; Elysium Basis $65.00 ÷ (0.250 g × 30 servings) = $8.67/g. All three verified 2026-09-09.
