Supplement analysis, lab reports, clinical dosing verification, certification examination, and side-by-side comparisons.
Six criteria that determine whether a supplement matches the dose and form used in the peer-reviewed research, or just borrows its reputation.
Compare each product’s Supplement Facts panel against the dose ranges used in the peer-reviewed trials that built the category’s reputation.
Whether the form on the label (chelated glycinate, root-only extract, full-spectrum, hydrolyzed peptides) matches the form the research used.
Cross-check brand purity and potency claims against publicly available Certificates of Analysis. Products without verifiable batch testing get flagged.
Proprietary blends hide per-ingredient milligrams. We treat them as the lowest tier of transparency since the math against clinical dosing becomes impossible.
GMP-certified USA production with third-party batch testing is the minimum bar for a daily supplement on this site.
Verified-purchase reviews across Amazon, brand sites, and forums, categorized by efficacy, side effects, and value. Patterns inform every limitations section.
Every category follows the same methodology. We start with the clinical research, build a framework, then measure every label against it.
For each category, we read the peer-reviewed research and identify the dose, form, and supporting compounds that produced measurable results. Those become the criteria.
We measure every product label against the framework. We cross-check brand claims against third-party Certificates of Analysis where available. Proprietary blends and undisclosed doses are flagged.
We review verified-purchase reviews across Amazon, brand sites, and forums. Reviews are categorized by efficacy, side effects, and value. Patterns inform the limitations section of each ranking.
