How dosing is usually reported

Dosages in the literature are reported in a handful of incompatible ways — total compound weight, elemental weight, or weight per kilogram of bodyweight. Two labels can list the same number and mean very different things.

Where a study is cited on this site, the dose is restated in the unit the study used, with the compound form named. Where a product label is referenced, the label's own unit is preserved. See our sourcing notes for how entries are compiled.

  • Elemental vs. compound weight
  • Per-serving vs. per-day
  • Standardized extracts and ratio notation
Nothing on this page is medical advice. Entries describe what the literature reports; they do not tell you what to take.
