Best NR Supplement: Nicotinamide Riboside Compared
Ad – we may earn a commission from links on this page. How we make money
We don't sell supplements; brands can't pay for placement; rankings use published testing and price per daily dose. How we rank
Independent of the brands we list: commission never changes a ranking. How we choose: form and dose, independent testing, ingredients and price per serving.

Nicotinamide riboside (NR) is a form of vitamin B3 that the body can turn into NAD+. Human trials agree that NR raises NAD+ in the blood, but they have not shown clear health benefits yet, so we rate the evidence D. If you still want to try it, this page compares the five NR products we have price and label data for. For the evidence, see our nicotinamide riboside guide.
Short answer: Best overall: Tru Niagen 300 mg (the single-ingredient product with named testing programs, as brand statements); Best budget: Vitality Pro NR 300 mg (lowest price per daily dose in both £ and $). Basis (with pterostilbene) and Paused (with B vitamins) are combination products and are not ranked. Prices, testing and every shop are in the picks below.

Our ranked picks

Best overall
Tru Niagen 300 mg, 30 capsules
A 300 mg nicotinamide riboside chloride capsule from the brand that sells under the Tru Niagen name. It is the single-ingredient NR product in our data that names the most testing programs.
Pros
- Names three testing programs (NSF Certified for Sport, Alkemist Assured, TESTED by SuppCo), all as brand statements
- Batch certificates of analysis by lot number on the brand site, per our product data
- Sold on the brand site in the US and through Healf in the UK
Cons
- Highest price per daily dose of the single-ingredient products in both $ and £
- Testing claims are the brand's own; check the NSF listing for the exact product before relying on it
- The Amazon.com and iHerb prices are not verified, and the Amazon.co.uk price was read through a search tool

Best budget
NR (nicotinamide riboside chloride) 300 mg, 90 capsules
A 300 mg nicotinamide riboside chloride capsule in a 90-capsule pack, with batch purity results published by the brand.
Pros
- Lowest price per daily dose on this page in both £ and $
- Publishes batch purity results from ISO 17025-accredited labs (brand statement)
- UK-made, per our product data
Cons
- No named certificate such as NSF or Informed Sport; the testing is the brand's own published results
- The brand page says 1 to 2 capsules; our price assumes 1 capsule (300 mg), so 2 capsules would cost twice as much a day

How we rank
We only rank products that are in our product data file, and we use only what that file records:
- Form and amount. Three products are single-ingredient capsules with 300 mg of NR chloride each (Tru Niagen, Vitality Pro and Life Extension). Paused adds B vitamins, vitamin C and Siberian ginseng, and Elysium Basis adds pterostilbene, so those two are shown but not ranked. We compare the amount of NR itself, not the weight of the pack, and we price one 300 mg dose a day.
- Third-party testing, as listed. We note a named testing program (for example NSF Certified for Sport) when our data lists one. Where the data says “brand statement”, we say so and do not count it as verified by us.
- Price per daily dose. We divide the pack price by the servings per pack, then scale to our basis: 300 mg of nicotinamide riboside (NR) chloride a day, which is 1 capsule of each single-ingredient product. Elysium Basis gives 250 mg of NR per 2 capsules, so its price is scaled up to 300 mg. Prices in different currencies are not converted, so $ and £ are only compared within their own currency.
Winner labels. “Best overall” goes to the cheapest product with a named testing program in that currency. “Best budget” goes to the lowest price per daily dose in that currency, whatever the testing. “Best tested” is only used when one product lists clearly more named programs than the rest. If no product qualifies for a label, we leave that label out.
Combination products. Paused and Elysium Basis are priced in the tables but are not given a label, because the extra ingredients mean they are not like-for-like with plain NR. Basis gives 250 mg of NR per 2 capsules, so its price is scaled to 300 mg.
Brand statements. Every testing claim for NR in our data comes from the brand’s own pages, not from a certificate we checked. We repeat them as claims.
Region. Elysium Basis has US and international offers only, and Life Extension’s NR capsule has a US offer only. Prices in pounds and dollars are not converted.
What we did not do. We have not tested these products ourselves, in a lab or by taking them. We did not rank by commission. Prices change, so each price shows the date it was checked. More in How we rank.
Price per daily dose
Basis: 300 mg of nicotinamide riboside (NR) chloride a day, which is 1 capsule of each single-ingredient product. Elysium Basis gives 250 mg of NR per 2 capsules, so its price is scaled up to 300 mg. Every number below is worked out from the pack price, servings per pack and amount per serving in our product data.

How to start
Studies have used 100 to 1,000 mg of NR a day for several weeks. Those are study amounts, not recommendations, and the trials we cite lasted 6 to 10 weeks, so long-term effects are not known. Most capsules here have 300 mg each; Elysium Basis gives 250 mg per 2 capsules. Check the label for the amount of NR itself rather than the pack weight, start with one capsule a day, and stop and ask your doctor or pharmacist if anything feels wrong. Our nicotinamide riboside guide covers the study doses and side effects.
Talk to your doctor or pharmacist
Talk to your doctor or pharmacist before you start any supplement, especially if you are pregnant or breastfeeding, take prescription medicine, or have a health condition. This matters most if you take regular medicine, or have kidney or liver problems. The full guide has the evidence, safety notes and citations.
How we chose
We compared five NR products (three single-ingredient capsules and two combination products) by form and amount, named third-party testing and price per 300 mg of NR. We have not tested any product ourselves, and commission does not affect the order.
FAQ
What is the best NR supplement?
From the five products we have data for: Tru Niagen has the most named testing programs (as stated by the brand), and Vitality Pro has the lowest price per daily dose in both pounds and dollars. Both supply 300 mg of NR chloride in a capsule. This is a short list, not a full market review.
Does NR actually work?
NR reliably raises NAD+ levels in the blood. A 2023 review of 25 human studies found few clinically relevant effects, so we can’t say it will improve your health. See the evidence guide for the details.
What is the difference between NR and NMN?
Both are building blocks the body can use to make NAD+. We explain the differences in NMN vs NR. We do not list or link NMN products on this site.
Why are Basis and Paused not ranked?
They add other ingredients (pterostilbene in Basis; B vitamins, vitamin C and Siberian ginseng in Paused), so their price is not like-for-like with plain NR. Our pterostilbene guide covers that ingredient.
How long have NR trials lasted?
The trials we cite lasted 6 to 10 weeks, so nobody knows yet what happens over years.
