What is this?
The interaction data in the HelloPharmacist supplement database is licensed from Natural Medicines Pro by TRC Healthcare (Therapeutic Research). HelloPharmacist pharmacists often add our own analysis and context on top of that licensed data — such as this Bottom Line summary and the notes on individual interaction pages — and any such commentary is noted as ours.Digitoxin (Crystodigin) is a heart medication with almost no cushion between the dose that steadies a rhythm and the dose that causes harm, so anything that changes how much of it your body absorbs deserves real attention. All 17 supplements on this list interact in exactly that way. Bulk fibers and gums such as psyllium and glucomannan can slow or reduce how much digitoxin reaches your bloodstream, and activated charcoal, the single major-rated entry, can pull the drug out of your system even after it has been absorbed, since digitoxin recycles through the gut.
Seven entries rate moderate and nine minor, most of them theoretical fiber effects, but with this little margin a weakened dose is not a small problem. Space fiber supplements, gums, and thickeners well apart from your digitoxin, and ask a pharmacist before using charcoal in any form.

Full Marshmallow + Digitoxin answerWhat Severity, Likelihood & Evidence Mean
Severity — How Serious It Can Be
- Major. Clinically significant; generally best avoided, or used only under direct professional supervision.
- Moderate. May need monitoring, a dose adjustment, or separating the times you take each one.
- Minor. Generally not clinically significant, but still worth noting and mentioning to your pharmacist.
- No known interaction. Checked against our sources with nothing documented — not the same as proven safety.
Likelihood — How Well It’s Documented
- Likely. Well-controlled human studies have demonstrated the likely existence of this interaction
- Probable. Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
- Possible. Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists
- Unlikely. Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Where This Data Comes From
- Interaction records are evidence-graded and sourced from the Natural Medicines database (TRC Healthcare), the same reference used by pharmacists and hospitals.
- Each entry links to a full report with the clinical detail, likelihood, evidence level, and citations for that exact combination.
- Content is reviewed by licensed HelloPharmacist pharmacists — see our data sources and editorial standards.
How Does Our Interaction Checker Work?
Behind every verdict on this page is a category system. Our source database doesn’t document supplement interactions drug-by-drug — it documents them against groups of medications that behave the same way (for example, “drugs processed by the CYP3A4 liver enzyme” or “blood-thinning medications”).
So the check works in three steps: (1) Digitoxin is classified into the pharmacology categories it belongs to, (2) every supplement interaction documented against any of those categories is inherited by Digitoxin, and (3) each ingredient keeps its own severity, likelihood, and evidence grades from the underlying record. That’s why one supplement can carry several records for one drug — it may interact through more than one category.
Digitoxin sits in 1 interaction category. Open any one to see what the group means:
Oral Drugs 17 ingredients
A pharmacology grouping from our source database: medications in this group share a property that certain supplements are known to interact with, so an interaction documented for the group applies to every drug in it.
17 of the supplement ingredients on this page reach Digitoxin through this category.
