Globemallow + Ferric Citrate
Ferric Citrate brand name: Auryxia.
We found no known interaction between Globemallow and Ferric Citrate in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the label for Ferric Citrate states a food rule worth keeping to.
Globemallow and Ferric Citrate
We checked these two against our interaction database. Here is what we found.
No Known Interaction Found
We did not find a documented interaction between Ferric Citrate and Globemallow in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.
Worth understanding: our licensed dataset holds no drug-interaction record for Globemallow at all — not against Ferric Citrate, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.
If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.
Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.
Globemallow safety at a glance
Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Some Ferric Citrate Products Have a Food Rule — Globemallow Should Not Break It
At least one FDA label for a product containing Ferric Citrate says to take it with food. If you take Globemallow on an empty stomach out of habit, keep them separate — and take Ferric Citrate with a meal where the label says to.
This may not be true of your version. Food instructions belong to the product, not the ingredient: two Ferric Citrate products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.
( 2.2 ) 2.1 Dosage for Hyperphosphatemia in Chronic Kidney Disease on Dialysis The recommended starting dose is 2 tablets, swallowed whole, 3 times per day with meals.
From the Dosage and Administration section of the FDA label we read for Ferric Citrate — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›
A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

From our pharmacist’s overview on the Ferric Citrate page
“Ferric citrate (Auryxia) does its work in the gut, binding dietary phosphate in kidney disease or supplying iron, and all 17 supplements on this list can interfere with how oral medicines get absorbed. That is worth real caution, starting with the single major-rated entry, activated charcoal, which adsorbs many drugs directly and can m…”

Where Globemallow and Ferric Citrate Sit Against Everything Else
Out of every supplement and medication people look up on HelloPharmacist, here is where these two land this week — and which way each has been moving.
#757 of 1,452 supplements looked up here in the last 7 days
#1,788 of 2,830 medications looked up here in the last 7 days
Position among everything looked up on this site, not a measure of how commonly either one is used or how important it is. A supplement can climb this list because of a news story. It counts every request to the page, automated ones included, and nothing here identifies anyone.
Where does our data come from?
- Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Globemallow is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
- Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Globemallow reference on this page ↓
- Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Globemallow and Ferric Citrate records this page draws on were last updated June 22, 2026.
- What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.
About Globemallow
What is Globemallow?
- Soothing skin irritation
- Cough and sore throat
- Digestive upset
- Minor wounds and inflammation
- Mouth and throat soothing
Globemallow refers to plants in the genus Sphaeralcea, which have a long history of traditional use among Indigenous peoples of the Americas, mainly as a soothing remedy for skin, throat, and digestive complaints. There is very little modern scientific research on its safety or effectiveness, so its benefits remain unproven. Talk to your pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or taking other medicines.
Sphaeralcea · Malvaceae · Leaves, flowers, roots, and whole aerial parts · Tea, poultice, dried herb, infusion
