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

This is a generic, unbranded ashwagandha root extract, NOT KSM-66 or Sensoril, the two clinically studied branded extracts named in the brief. BulkSupplements does not appear to license either trademark, so buyers lose the specific standardization/clinical backing those brands offer.

In plain language

Why this scored this way

This BulkSupplements Ashwagandha Extract Powder scores 7.4, making it a mid-tier product with both strengths and weaknesses. It delivers the full 600.0mg trial dose of Ashwagandha with grade B evidence (promising human data, not yet comprehensive). The quality transparency (6.0) is limited by the lack of third-party testing. At $0.13/day it's priced well for what you get.

What drives the score up

  • Dose-evidence score of 8.0 reflects good alignment with trial doses.
  • Value score of 10.0 at $0.13/day.
  • Ashwagandha is dosed at the full research level with grade B evidence (promising human data, not yet comprehensive).

What drags it down

  • 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 good value at $0.13/day.
  • You want Ashwagandha from a BulkSupplements product.
  • You want doses that align with published research.

Why you might skip it

  • You want third-party verified purity.
  • You want a product with a publicly available CoA.
  • You want stronger transparency (this scores 6.0).
