Label-first supplement analysis. Clinical dose checks, ingredient form verification, and side-by-side comparisons. Most bottles never reach the dose the research used. We find the few that print it.
We read the labels of 34 prostate supplements. 26 underdose saw palmetto or hide it in a blend.
See all five ranked →We read the labels of 41 berberine supplements. 27 never say which plant, or which part of it, the berberine came from.
See all five ranked →We read the labels of 31 magnesium glycinate supplements. 21 deliver under 200 mg of elemental magnesium, and 22 never print the compound weight.
See all five ranked →Six checks that decide whether a supplement carries the dose and form the peer-reviewed research used, or just borrows the ingredient's reputation.
Every Supplement Facts panel is compared with the dose ranges used in the trials that made the ingredient famous. Half the studied dose is a different product.
Whether the form printed on the label (chelated glycinate, standardized extract, hydrolyzed peptide, root versus leaf) is the form the studies used.
Brand purity and potency claims are checked against Certificates of Analysis where a brand publishes them. No verifiable batch testing, flagged.
Proprietary blends hide the milligrams. We treat them as the lowest tier of transparency because the dose math becomes impossible.
GMP-certified production in the USA with batch testing is the floor for a supplement taken every day.
Verified-purchase reviews across retail sites and forums, sorted by effect, side effects, and value. Patterns feed every limitations section.
Every category follows the same sequence. Research first, framework second, then every label measured against it.
For each category we read the peer-reviewed research and write down the dose, the form, and the supporting compounds that produced measurable results. Those become the criteria.
Every product label is scored against the framework. Brand claims are checked against third-party Certificates of Analysis where available. Proprietary blends and missing doses are flagged.
Verified-purchase reviews across retail sites, brand sites, and forums are sorted by effect, side effects, and value. Recurring complaints shape the limitations we print.
