HelloPharmacist Bottom Line
Our Pharmacist Explains
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.

Trioxsalen (Trisoralen) works by making skin extra sensitive to UVA light for psoriasis and vitiligo treatment, and that mechanism is exactly why this list deserves careful reading rather than a skim. Twenty of the 37 supplements and herbs on file add a photosensitizing effect of their own on top of the drug's, raising the odds of a burn-like reaction, and the one major-rated entry, activated charcoal, can adsorb the drug in the gut and blunt the treatment itself.

The remaining 17 entries also change how oral medicines are absorbed, mostly bulky fibers such as glucomannan that can slow or shrink the dose that actually reaches you. Space those well apart from the tablet and let the full report fill in the specifics. With 26 moderates and 10 minors sitting behind that single major, charcoal deserves your attention first, and anything that adds sun sensitivity, chlorophyll included, comes a close second.

What 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) Trioxsalen is classified into the pharmacology categories it belongs to, (2) every supplement interaction documented against any of those categories is inherited by Trioxsalen, 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.

Trioxsalen sits in 2 interaction categories. Open any one to see what the group means:

Photosensitizing Drugs 20 ingredients

Medications that make skin more sun-sensitive. Supplements with the same property can compound it.

20 of the supplement ingredients on this page reach Trioxsalen through this category.

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 Trioxsalen through this category.

Trioxsalen & Supplements: Common Questions

What supplements interact with Trioxsalen?
In our interaction database, 37 supplement and herbal ingredients have an interaction with Trioxsalen on file — 1 rated major, 26 moderate, and 10 minor. That number sounds scarier than it is: severity matters far more than the count, which is why the list on this page is ranked instead of alphabetical. Start at the top. The highest-ranked right now: Activated Charcoal, Bergamot, Chenopodium Oil.
Which Trioxsalen supplement interactions are the most serious?
Focus on the major group: Activated Charcoal. A major rating means the combination can be clinically significant, not that harm is guaranteed — but it's exactly the kind of thing to run past your pharmacist before your next dose, not after. Jump to the ranked list.
Can I take vitamins or supplements while on Trioxsalen?
That depends entirely on which supplement. The honest answer for Trioxsalen is in the ranked list above — and if what you take is a combination product with a dozen ingredients, don't check them one by one: photograph the label with our scanner and we'll check the whole thing at once. Try the label scanner or the interaction checker.
Do brands like Trisoralen have the same supplement interactions as Trioxsalen?
Yes — Trisoralen all contain Trioxsalen, so everything on this page applies to them equally. Interactions belong to the active drug, never to the brand on the box; the same is true of generics.
Where do these interaction ratings come from?
Every rating comes from the Natural Medicines database — the same evidence-graded reference pharmacists and hospitals use — and each interaction carries three separate grades: severity (how bad it can be), likelihood (how well it's documented in studies and case reports), and an evidence level. Our pharmacists review the content; we never let an AI decide an interaction. See how to read the ratings and our editorial policy.
What about Trioxsalen and my other medications?
This page covers Trioxsalen against supplements and herbal ingredients. Checking Trioxsalen against your other prescription or OTC medications is a different tool — our drug interaction checker covers that side. Head to the drug–drug interaction checker.
