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 Green tea leaf powder / matcha is unrated

Whole-leaf powder carries a lower, unstandardized catechin concentration than a standardized extract, so mg of powder and mg of extract are not equivalent doses; no human comparison was verified, so it is not ranked.

Why Decaffeinated green tea extract is unrated

Caffeine removed (relevant to stimulant load, since caffeine is tracked as its own compound); no human comparison of catechin efficacy or safety vs caffeinated extract was verified, so it is not ranked.

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.
