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.

Fruquintinib (Fruzaqla) is an oral targeted therapy for advanced colorectal cancer, which means keeping its blood level steady is part of what makes it work, and I would treat this supplement list with genuine care. Of the 168 ingredients on file, the large majority interact through CYP3A4, the liver enzyme that clears the drug, so they can push its level up or drag it down. Grapefruit raises it and St. John's wort lowers it, and both rank among the six major-rated entries.

A second group of 38 ingredients, including regular beer or wine, adds strain to a liver that is already processing a cancer medicine. A smaller set of 17, with activated charcoal the standout, can blunt absorption of anything swallowed, so space such products well apart from your dose. The 124 moderate and 38 minor entries mostly repeat these same mechanisms with less force; the six majors carry most of the real risk here.

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

Fruquintinib sits in 3 interaction categories. Open any one to see what the group means:

Cytochrome P450 3A4 (Cyp3A4) Substrates 121 ingredients

A drug-metabolism group: these medications are processed by the named liver enzyme (a cytochrome P450). Supplements that speed this enzyme up or slow it down can lower or raise the medication's levels in your body.

121 of the supplement ingredients on this page reach Fruquintinib through this category.

Hepatotoxic Drugs 38 ingredients

Medications with known liver considerations. Supplements that can stress the liver add to the load.

38 of the supplement ingredients on this page reach Fruquintinib 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 Fruquintinib through this category.

Fruquintinib & Supplements: Common Questions

What supplements interact with Fruquintinib?
Our database currently documents 168 ingredients with a known Fruquintinib interaction (6 major, 124 moderate, 38 minor). The practical move: scan the major group first, then look up the exact supplements you take rather than reading all 168. The highest-ranked right now: Grapefruit, Siberian Cocklebur, Activated Charcoal.
Which Fruquintinib supplement interactions are the most serious?
The 6 major-rated combinations — led by Grapefruit, Siberian Cocklebur, Activated Charcoal, Beer and St. John's Wort — deserve real caution: these are the ones generally best avoided, or used only with your prescriber watching. If you take any of them today, don't panic and don't stop anything abruptly — call your pharmacist first. Jump to the ranked list.
Can I take vitamins or supplements while on Fruquintinib?
Plenty of supplements coexist fine with Fruquintinib; a shorter list does not. Rather than memorizing it, check the specific ingredients on your labels — the ranked list above covers every one we've checked, and multi-ingredient products can be checked label-by-label with our scanner. Try the label scanner or the interaction checker.
Do brands like Fruzaqla have the same supplement interactions as Fruquintinib?
Yes — Fruzaqla all contain Fruquintinib, 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 Fruquintinib and my other medications?
This page covers Fruquintinib against supplements and herbal ingredients. Checking Fruquintinib against your other prescription or OTC medications is a different tool — our drug interaction checker covers that side.
