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.

Editorial notes

NOT a grape-skin-extract resveratrol as the brief assumed, NTD's product is standardized 98% trans-resveratrol from Polygonum cuspidatum (Japanese knotweed), the same source used by most commercial resveratrol brands. Dose (1000mg/day at 2 capsules) is at the high end of studied ranges. Price range $44.99-$84.99 across sizes; the 90ct/$84.99 price point tracked via an independent third-party pricing tracker ($0.94/serving).
