Independent of the brands we list: commission never changes a ranking. How we choose: form and dose, independent testing, ingredients and price per serving.

Resveratrol is a plant compound found in red grape skins that became famous after exciting results in lab animals. In people the picture is much less exciting: small improvements in blood sugar markers in one review, no effect on inflammation, cholesterol or blood pressure in others. We rate the evidence C, with little proof that it does much for healthy aging. If you are still curious, this page compares the four capsules we have data for. Read the resveratrol guide first.
Short answer: Best budget (US$): NOW Resveratrol 200 mg (US offer only); Best budget (UK £): SupplementsWise Resveratrol 150 mg; 40 mg capsules: Life Extension Optimized Resveratrol Elite (US$) and Pure Encapsulations Resveratrol (UK £ and US$). No product has a named testing certificate in our data. Prices, testing and every shop are in the picks below.

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. The four products are capsules with different strengths of trans-resveratrol, the form used in research: 40 mg (Life Extension and Pure Encapsulations), 150 mg (SupplementsWise) and 200 mg (NOW). We compare the amount of trans-resveratrol itself and scale every price to 40 mg, so the table shows cost per mg, not a daily plan.
- 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: 40 mg of trans-resveratrol, the strength of the two lower-dose capsules. It is a price basis, not a recommended dose. The other two capsules give 150 mg and 200 mg each, so their price is scaled down to 40 mg to compare cost per 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.
No certificates. No product has a named third-party testing certificate in our data, so no product qualifies for Best overall or Best tested. Only Best budget is awarded.
The cheapest are the strongest. The two Best budget picks give 150 mg and 200 mg per capsule, so they are cheap per mg but are not 40 mg products. Which amount is right for you is a question for a doctor or pharmacist.
Region. NOW’s 200 mg capsule has a US offer only, and SupplementsWise has a UK 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: 40 mg of trans-resveratrol, the strength of the two lower-dose capsules. It is a price basis, not a recommended dose. The other two capsules give 150 mg and 200 mg each, so their price is scaled down to 40 mg to compare cost per 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
The four capsules give 40 mg, 150 mg or 200 mg of trans-resveratrol each. Those are label amounts, not recommended doses, and the studies we cite use different amounts, so see the resveratrol guide for what trials gave and how much reaches the bloodstream. Look for the amount of trans-resveratrol in mg, a testing certificate you can check, and compare by price per mg, not pack price.
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. Ask especially if you take regular medicine, such as blood thinners or diabetes medicine, or have a hormone-sensitive condition. The full guide has the evidence, safety notes and citations.
How we chose
We compared four resveratrol capsules by trans-resveratrol per capsule, named third-party testing and price per 40 mg of trans-resveratrol. We have not tested any product ourselves, and commission does not affect the order.
FAQ
What is the best resveratrol supplement?
From our data: SupplementsWise (pounds) and NOW (dollars) have the lowest price per 40 mg of trans-resveratrol, but their capsules are much stronger than 40 mg. None lists a third-party testing certificate in our data.
Does resveratrol slow aging?
There is little proof it does much for healthy aging in people. Animal results were exciting, but human trials have been mixed. See the guide.
Is resveratrol on Amazon reliable?
Look for a testing certificate you can check for the exact batch. Our data has an Amazon.com listing for Pure Encapsulations, but its price was read through a search tool and is not verified.
What does trans-resveratrol mean?
It is the form of resveratrol used in research. Supplements usually list it as “trans-resveratrol” with milligrams per serving.
