The evidence in words
The interaction
Activated Charcoal and Oral contraceptives — a timing interaction. Adsorbs oral drugs — separate by hours to avoid failure.
What to do
They are fine to use in the same regimen, but not at the same time. Separate the doses (typically by 2–4 hours) so one does not block the other's absorption.
About Activated Charcoal
Activated charcoal is a highly porous carbon that adsorbs many substances in the gut.
The bigger picture
Supplement–drug and supplement–supplement interactions are the reason a stack should be read as a system, not a list. This platform's interactions graph maps them; the medication side always belongs with the person who prescribes it.
