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.Ferrous sulfate (Feosol) is a workhorse iron pill for low iron, and its supplement list is short and mild. Just two ingredients are on file, both rated minor, so serious trouble is unlikely for most people, though your prescriber should still know what you take. Both entries come back to iron itself: arum contains oxalate that can grab iron in your gut and cut how much you absorb, while liver extract carries its own heme iron and quietly adds to your total intake.
The two pull in opposite directions. Arum works against the reason you take ferrous sulfate, so if you use it, space the doses well apart. Liver extract stacks iron on iron, which mostly means more stomach upset, though high doses over long stretches could let iron build past what you need. Neither is cause for alarm, just make sure all your iron gets counted.

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) Ferrous Sulfate is classified into the pharmacology categories it belongs to, (2) every supplement interaction documented against any of those categories is inherited by Ferrous Sulfate, 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.
Ferrous Sulfate sits in 1 interaction category. Open any one to see what the group means:
Iron 2 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.
2 of the supplement ingredients on this page reach Ferrous Sulfate through this category.

What supplements interact with Ferrous Sulfate?
Our database currently documents 2 ingredients with a known Ferrous Sulfate interaction (0 major, 0 moderate, 2 minor). The practical move: scan the major group first, then look up the exact supplements you take rather than reading all 2. The highest-ranked right now: Arum, Liver Extract.
Which Ferrous Sulfate supplement interactions are the most serious?
None of the Ferrous Sulfate supplement interactions on file are currently rated major. The most significant are rated minor. Still worth a quick look through the ranked list for anything you take daily. Jump to the ranked list.
Can I take vitamins or supplements while on Ferrous Sulfate?
Plenty of supplements coexist fine with Ferrous Sulfate; 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 Feosol have the same supplement interactions as Ferrous Sulfate?
Yes — Feosol all contain Ferrous Sulfate, 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.
