What to check on the label

  • Whether the label says trans-resveratrol with a purity percentage, or only 'resveratrol' or 'Japanese knotweed extract'.
  • Whether the milligrams refer to the compound or to the extract it comes from.
  • Powders list a scoop size. Check that it matches the serving in the catalog.

Amounts are per label serving as recorded in the catalog and are not a recommendation. Testing status reflects what the brand lists. Nothing here is medical advice.

How we scored this product Show the full breakdown
Dose vs. studies (50%) Why 6.2 of 10. Primary ingredient is Resveratrol (evidence grade C). It delivers 1000 mg, inside the studied range of 150–1000 mg. Read the rule → 6.2
Transparency (20%) Why 8.0 of 10. Earned points for public certificate of analysis and independent third-party testing and all doses disclosed. Read the rule → 8.0
Value (10%) Why 9.4 of 10. One day at the trial dose costs about $0.52. That is one of the cheaper options in the catalog (72 of 313 by cost per effective day). Read the rule → 9.4
Formulation (10%) Why 5.0 of 10. No published absorption advantage or disadvantage on file. The default of 5 is not a criticism. Read the rule → 5.0 Default. No absorption data on file.
Safety (5%) Why 8.5 of 10. Baseline 5.0. Third-party testing adds 2.0. Public lab certificate adds 1.5. NSF, USP or Informed Choice certification adds 1.5. Active safety signal subtracts 3.0. Read the rule → 8.5
Community sentiment (5%) Why 7.5 of 10. No external reviews found, so community sentiment defaults to neutral. Community never counts as clinical evidence. Read the rule → 7.5
Composite How this 6.1 is built. 0.50 × 6.2 + 0.20 × 8.0 + 0.10 × 9.4 + 0.10 × 5.0 + 0.05 × 8.5 + 0.05 × 7.5 = 6.1 out of 10. Safety caps applied after. 6.1

Value10%9.4
Formulation10%5.0
Safety5%8.5
Community5%7.5

Evidence gates dose: the evidence grade sets the ceiling, and the dose decides how much of that ceiling the product reaches. Value = inverse of price-per-trial-dose-day. Community = mean sentiment of external reviews. Safety caps applied after weighting.

This score is our editorial judgment, not a scientific standard. We combine published evidence, dose, price, transparency, and consumer signals into one composite: this is our method, not a peer-reviewed clinical rating. A higher score means a product does better on the factors we weight, not that it is medically proven to work.

Why this scored this way

This ProHealth Longevity Trans-Resveratrol Plus - 1000 mg per serving scores 6.9, making it a mid-tier product with both strengths and weaknesses. It delivers 420mg of Quercetin, inside the studied range of 250–1000mg with grade B evidence (promising human data, not yet comprehensive).

What drives the score up

  • Dose-evidence score of 6.2 shows decent alignment with trial doses.
  • Tested by independent lab (transparency 8.0).
  • Quercetin is dosed at the full research level with grade B evidence (promising human data, not yet comprehensive).

What drags it down

  • Resveratrol (1000.0mg is 200% of the 500mg trial dose) is well above the trial dose. More is not always better.

Why you'd choose it

  • You want good value at $0.52/day.
  • You want Quercetin from a ProHealth Longevity product.
  • You prioritise tested by independent lab products with public lab certificates.

Why you might skip it

  • You want a standard dose of resveratrol (this product is well above it).
Question 1

Does the molecule work?

The science behind each active ingredient, independent of which brand sells it.

Resveratrol

The famous red-wine molecule; longevity claims have outrun the human evidence.

3 landmark RCTs · US: Dietary supplement · EU: Authorised Novel Food (2016/1866)
Quercetin

Best-studied 'senolytic' ingredient, though evidence is early.

4 landmark RCTs · US: Dietary supplement · EU: Food supplement (extract-dependent)

Full ingredient breakdown

Every active in this formula, its declared dose per serving, the dose used in the primary human trial, how much of that trial dose this product delivers, and the evidence grade for the ingredient itself.

IngredientDose / servingResearch dose% of researchEvidence grade
Resveratrol1000 mg500 mg200%C
Quercetin420 mg500 mg84%B

Percentages are dose per serving ÷ primary trial dose. Below 50% means the formula is unlikely to reproduce the trial outcome for that active. Grade A = multiple large human RCTs. Grade F = no human evidence. How grades work. Full glossary →

Important to know
Resveratrol"Resveratrol" products that don't specify trans-isomer content are unmeasurable in practice. Cis-resveratrol is biologically inactive.
QuercetinPlain quercetin dihydrate has poor absorption. Phytosome forms deliver 10 to 20× more into blood.

Editorial notes

A high-dose (1000mg) trans-resveratrol capsule using the branded Veri-te™ ingredient plus an undisclosed-dose absorption blend; solid dose but blend opacity limits full verification.
