Doses are declared per serving in mg. “By weight” is the share of the ingredient that is the nutrient itself (e.g. elemental magnesium in a magnesium salt).

Why Ginger root/rhizome extract (unstandardized or ratio extract) is unrated

Extract mass on a label (a 4:1 extract, a supercritical CO2 extract, a dry aqueous extract) represents very different amounts of ginger, and no verified human study ranks extract types against each other or against powder.

Why Ginger extract standardized to gingerols (and gingerol/shogaol marker rows) is unrated

A declared gingerol percentage describes composition, not demonstrated superiority; no verified comparative trial. Rows whose own name is the marker ("Gingerols 25 mg") are the marker mass, not ginger, so they are recorded without a dose to avoid double counting with the extract row they sit under.

Tiers summarize published comparative bioavailability or outcome evidence for each form (see methodology). This page describes the market; it is not a recommendation to take either form. Talk to a clinician about what's right for you.
