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 is scored on six pillars:
- Dose honesty: Does the product contain the amount stated on the label? We check against published third-party assay results when available.
- Evidence: NR has evidence grade B. Products that cite relevant trials score higher.
- Price per month: Total monthly cost based on label serving recommendations.
- Third-party testing: Does the brand publish a Certificate of Analysis (CoA) from an independent lab?
- Transparency: Is the full formula public? Are all ingredient amounts disclosed?
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.
