How we scored this product Show the full breakdown
Bevisning 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. Säkerhet 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.

Redaktionellt notes
High per-serving dose (1000mg) at a low price, but the vendor page doesn't specify trans-resveratrol purity, and unlike DoNotAge/Life Extension it's not marketed or verified as pure trans-isomer, a meaningful gap for a sirtuin-activator claim.
Why this scored this way
This BulkSupplements Resveratrol Powder (trans-Resveratrol, from Polygonum cuspidatum) scores 5.2, making it among the lowest-scoring produkter we track. It delivers the full 1000.0mg trial dose of Resveratrol with grade C evidence (mostly preclinical, limited human data). The quality transparency (6.0) is limited by the lack of third-party testing.
What drives the score up

What drags it down
- Dose-evidence score of 4.1 is below average for the site.
- Resveratrol (1000.0mg is 200% of the 500mg trial dose) is well above the trial dose. More is not always better.
- No third-party testing, which caps the quality transparency.
- Quality transparency of 6.0 is below the site average.
- Limited consumer feedback (community score: 6.0).
Why you'd choose it
- You want a reasonably priced sirtuin activator product.
Why you might skip it
