Summary Which NR supplement offers the best balance of dose, price, and testing? Show / hide ↓
NR, or nicotinamide riboside, is a substance the body uses to make NAD+. Human studies using 300 to 1,000 mg daily have raised blood NAD+ levels by about 40 to 60% within two weeks, but this does not prove longer life or better health. The ranking compares 26 products from 13 brands using dose, evidence, price, testing, transparency, formulation, safety, and community feedback. Its top three are presented as the best evidence-per-dollar choices, with monthly prices of $55, $34.99, and $24. Most listed products are marked as tested, although published Certificates of Analysis are available for only some products. The article gives NR a B evidence grade and stresses that the scores are editorial judgments, not a scientific standard.
What this means for you: For a buyer, prioritize a clearly disclosed product providing 300 to 1,000 mg daily, independent testing, and a reasonable price. The ranking can help compare products, but it does not show that NR prevents ageing or extends life.

What is NR?
NR (nicotinamide riboside) is a NAD+ precursor that competes with NMN. NR was first characterized in 2004 and has a longer clinical trial record than NMN. Human trials at 300 to 1,000 mg per day show consistent 40 to 60 percent increases in blood NAD+ within two weeks. NR is generally recognized as safe by the FDA (unlike NMN, which the FDA has classified as a drug candidate). Both molecules end up as NAD+ in the same cellular pool. The choice between NR and NMN mostly comes down to price, regulatory status, and third-party testing quality.
Evidence grade: B. The other NAD+ precursor; more human trial data than NMN, but at lower doses. Read the full evidence review: NR ingredient page.
How we rank NR supplements
Every NR product in our database gets the same overall score, built on six weighted components:
- Dose vs studies (50%): How close the label dose is to the dose used in human trials for NR. Products far above or below the studied dose lose points.
- Transparency (20%): Is the full formula public, with every ingredient amount disclosed, and a published Certificate of Analysis?
- Value (10%): Monthly cost at the studied dose, not the sticker price of the bottle.
- Formulation (10%): Form and co-ingredients compared with the forms used in trials. Unproven delivery claims add nothing.
- Safety (5%): Doses above upper intake levels or with documented adverse-event signals lose points.
- Community (5%): Verified review signals from independent platforms, weighted low and never able to override the evidence components.
See the full methodology for the scoring formula.
What to look for in a NR supplement
- Dose: Human trials use 300 to 1,000 mg per day. The Niagen brand (patented NR) is the most studied.
- Form: NR chloride (nicotinamide riboside chloride, Niagen) is the form used in every major clinical trial.
- Purity: Look for products with published CoA showing NR content. Niagen-branded products carry ChromaDex certification.
- Price: NR is more expensive than NMN, ranging from $30 to $60 per month at 300 mg doses. Bulk NR products may be cheaper but harder to verify.
- Regulatory: NR is FDA-GRAS. NMN is currently classified as a drug candidate. This does not affect efficacy, but affects legality in some markets.
