Pau d’arco

These are the amounts published trials administered — not a recommendation, and not a dose to copy. Trial participants were screened, supervised and given a characterised preparation. What is in a retail bottle is frequently not what was studied, and the amount that suits one person is not general advice.

• Studied for General supplement use

  500–1000 mg

  Not enough

  Bark powder or extract capsule

  Trial dosing is not established for pau d’arco. These are retail label amounts with no controlled human study supporting them, and bark lapachol content varies enormously between batches and species.

This is general information about food, not medical advice. It cannot diagnose, treat or replace guidance from a clinician who knows your history.

None of the timings below were directly compared in a trial. They reflect how the research happened to dose, or what the pharmacology implies — which is not the same as a timing being better.
