Choosing the right resveratrol supplement can feel overwhelming with dozens of options available. To simplify your decision, we've put our three top-ranked products head-to-head: PartiQlar Pure Resveratrol, Toniiq Ultra High Purity, and Double Wood Supplements Resveratrol.
Let's dive deep into how they compare across purity, potency, value, and real-world effectiveness.
Trans-resveratrol purity determines how much active compound you're actually getting:
PartiQlar: ≥99% Trans-Resveratrol
The gold standard. PartiQlar's pharmaceutical-grade purity means virtually every milligram is active trans-resveratrol. This exceptional purity is achieved through advanced extraction and refinement processes.
Toniiq: 98% Trans-Resveratrol
Excellent purity that's nearly as high as PartiQlar. The 2% difference is negligible for most users, and Toniiq backs this up with third-party testing verification.
Double Wood: ~95% Trans-Resveratrol
Solid purity that exceeds the minimum threshold for effectiveness. While slightly lower than the premium options, 95% still ensures you're getting primarily active compound.
Winner: PartiQlar (by a small margin), though all three exceed industry standards.
PartiQlar: 500mg per capsule
Ideal daily serving size aligned with research showing optimal anti-aging benefits at 250-500mg. One capsule provides a full therapeutic dose.
Toniiq: 600mg per capsule
Highest potency of the three. The 600mg dose is excellent for those seeking maximum longevity support or who have been supplementing for a while and want to increase their intake.
Double Wood: 500mg per capsule
Matches PartiQlar's potency with a research-backed 500mg dose. Perfect for daily maintenance and general anti-aging support.
Winner: Toniiq for those wanting maximum potency; PartiQlar and Double Wood tie for optimal standard dosing.
This is where purity matters. Let's calculate the actual active trans-resveratrol per serving:
Winner: Toniiq delivers the most active compound, followed closely by PartiQlar.
PartiQlar: Premium Pricing
Expect to pay $35-50 per month. The highest-purity formula commands premium prices, but you're paying for pharmaceutical-grade quality and sleek direct-to-consumer convenience.
Toniiq: Mid-Premium Pricing
Typically $30-42 per month. Excellent value considering the high 600mg potency and 98% purity. The dedicated affiliate program often means promotional pricing is available.
Double Wood: Budget-Friendly
Usually $18-28 per month. Outstanding value for those who want quality resveratrol without premium pricing. Available through Amazon with frequent Subscribe & Save discounts.
Cost per mg of actual trans-resveratrol (approximate):
Winner: Double Wood for best value; Toniiq for best premium value.
PartiQlar: Ultra-high purity enhances bioavailability. The cleaner the formula, the less your body has to process. No added absorption enhancers reported, but the exceptional purity compensates.
Toniiq: The "Plus" in the product name suggests additional bioavailability support, though specific enhancers aren't clearly disclosed. The micronized particles may improve absorption.
Double Wood: Standard formulation without specific absorption enhancers. Still effective due to solid purity, but may benefit from taking with healthy fats.
Winner: PartiQlar and Toniiq tie for superior formulation; all three absorb well when taken with food containing fats.
PartiQlar: Direct-to-consumer brand with premium positioning. Clean website, transparent about purity levels, sleek modern branding that appeals to health-conscious millennials and Gen Z.
Toniiq: Established brand with extensive customer reviews (thousands of verified purchases). Transparent about testing, manufacturing, and sourcing. Strong reputation in the longevity community.
Double Wood: Well-known supplement brand with huge product catalog. Massive review volume on Amazon (20,000+ reviews) provides social proof. Transparent about ingredients and testing.
Winner: Toniiq for established trust; PartiQlar for premium brand experience; Double Wood for mass-market confidence.
All three are manufactured in GMP-certified facilities and include third-party testing. All are non-GMO. This is a three-way tie—they all meet high quality standards.

Honestly, no. All three are excellent products that will deliver real benefits. Your choice comes down to priorities:
If I could only recommend one? I'd suggest starting with Toniiq. It offers the best balance of purity, potency, and value while being backed by thousands of verified reviews. After 2-3 months, you can evaluate results and decide if you want to upgrade to PartiQlar's ultra-premium formula or stick with Toniiq's proven effectiveness.
