Overview

Swanson's Activated Charcoal supplement packs 260mg of activated charcoal powder per capsule, with a 520mg dose delivered across two capsules per serving, in a 120-capsule bottle aimed at digestive comfort.

Activated charcoal is used in supplement form for occasional digestive discomfort, working by binding to substances in the gut rather than through a nutrient or vitamin mechanism. The listing's 520mg per-serving figure implies a two-capsule serving size even though each individual capsule carries 260mg, which is worth checking against the label before dosing.

  • 260mg activated charcoal powder per capsule
  • 520mg per two-capsule serving
  • 120 capsules per bottle
  • Positioned for digestive comfort support

Who it's for

Adults wanting an activated charcoal capsule for occasional digestive support. Not intended as a treatment for ongoing digestive conditions, which should be discussed with a doctor.
