Monterey Pine + Ferric Citrate

Ferric Citrate brand name: Auryxia.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Monterey Pine 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.

Monterey Pine 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 Monterey Pine 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 Monterey Pine 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.

What Monterey Pine Itself Has Been Linked To

This is not an interaction — nothing below involves Ferric Citrate. It is the side-effect record for Monterey Pine on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Monterey Pine, this list is the first place to look.

Everything above comes from the Natural Medicines adverse-effect record for Monterey Pine — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Ferric Citrate’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Ferric Citrate column appears here.

How to take them

Some Ferric Citrate Products Have a Food Rule — Monterey Pine Should Not Break It

At least one FDA label for a product containing Ferric Citrate says to take it with food. If you take Monterey Pine 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. See the Ferric Citrate drug page ›

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…”

About Monterey Pine

What is Monterey Pine?

Monterey Pine
  • Antioxidant support
  • Skin and aging concerns
  • Circulation support
  • Inflammation
  • Respiratory comfort

Monterey Pine is mainly a timber tree, and human evidence for its use as a supplement is very limited. Some pine bark extracts are studied for antioxidant effects, but most claims specific to Monterey Pine are not well proven. Talk to a pharmacist or doctor before using any pine-based product.

Pinus radiata · Pinaceae · Bark, needles, and essential oil · Bark extract supplements, essential oil, needle tea

An interaction check asks whether these two react with each other — it does not ask whether Monterey Pine is a good idea for someone in your situation. Here is what our Monterey Pine record says about it on its own.

Monterey Pine: dosing

There is no established standard dose for Monterey Pine. Because products vary widely in strength and form, a safe, proven amount has not been set.If you choose to use a pine-derived product, follow the directions on the label and do not exceed them. Essential oils are for external or aromatherapy use only unless a professional advises otherwise.
