Criterion by criterion
The five criteria every review is scored on, published on the grading page. The overall score is their average.
Evidence for the marketed claim
How strong the research is for what the product is actually sold to do — not for the ingredient in general.
Dose against the studied amount
Whether one serving delivers the amount used in the research behind the claim.
Label transparency
Whether the Supplement Facts panel is published in readable text and every active amount is disclosed.
Value against the generic equivalent
Cost per gram or per dose of the active ingredient, compared with the plainest version of the same thing.
Safety and tolerability
Known risks and interactions, how well characterised they are, and whether the label warns about them.
Dose against the studied amount
What one labelled serving delivers, placed against the range on each ingredient’s evidence page. Where a label gives no figure, there is nothing to place, and that is the finding.

What it actually costs
Price divided by labelled servings, from a dated listing. A serving is whatever the label calls one, which is why the studied-dose row matters more than the headline figure.
- About $34.11 for 60 caplets at US supplement retailers, in listings read on 28 September 2026. No per-serving figure: servings not recorded.
- $14.99 for 8 servings on Amazon.com with an on-page coupon, against a usual listed price of about $30, in listings read on 28 September 2026. We could not confirm a current price for the 14-serving bag. No per-serving figure: servings not recorded.

How this comparison is built
- Scores are the ones already published in each review. Nothing is re-scored for the comparison, and a product leads a criterion only when it outscores the rest.
- Doses are read from the label rows in each review and placed against the studied range on the matching ingredient page. A figure that is not printed is never estimated.
- Costs use a dated retailer price divided by labelled servings. Prices in different currencies are never ranked against each other.
- Only products in the same category, or ones a review names as an alternative, can be compared. Commission never changes what appears here.
