No Known Interaction

Medically reviewed by Dr. Brian Staiger, PharmD, BCPS · Updated July 2026 · Pair last verified Sep 13, 2026

The bottom line No known interaction

We found no known interaction between Rna And Dna 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.

Interaction report

Rna And Dna 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 Rna And Dna 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 Rna And Dna 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 to actually watch for

What Rna And Dna Itself Has Been Linked To

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

Itching / Swelling Additional detail
“Orally, RNA and DNA are well tolerated when consumed in food or enteral nutrition. Nucleotides seem to be well tolerated when consumed in medicinal amounts for up to 14 days. No adverse effects have been reported. Subcutaneously, RNA can cause itching, redness, and swelling at the injection site.”

Everything above comes from the Natural Medicines adverse-effect record for Rna And Dna — 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 — Rna And Dna Should Not Break It

At least one FDA label for a product containing Ferric Citrate says to take it with food. If you take Rna And Dna 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.

Everything else you take

See Every Supplement That Interacts With Ferric Citrate

This page covers Rna And Dna only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Ferric Citrate page lists 17 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Coffee Charcoal (moderate), European Mandrake (moderate), Glucomannan (moderate) and Guar Gum (moderate).

By severity: 1 major · 7 moderate · 9 minor.

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 Rna And Dna

What is Rna And Dna?

Anti-aging
Energy and vitality
Immune support
Skin health
General cellular support

RNA and DNA supplements contain nucleic acids, usually taken from yeast or fish, and are marketed for anti-aging, energy, and immune support. There is very little solid human evidence that taking these by mouth provides any of these benefits, and the body breaks them down during digestion. They are best avoided by people with gout or high uric acid, and there is not enough safety data to recommend them during pregnancy or breastfeeding.

Nucleic acids (RNA and DNA) typically extracted from yeast, fish, or other animal sources · Tablets, capsules, powders, combination 'nucleic acid' supplements

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

Rna And Dna: dosing

There is no well-established standard dose for RNA and DNA supplements, and no clear evidence on how much, if any, is helpful. Products vary widely in their source and strength.If you choose to use one, follow the directions on the product label and do not exceed the recommended amount.

Taking Rna And Dna and Ferric Citrate Together: Common Questions

Is it safe to take Rna And Dna with Ferric Citrate?

If you take Rna And Dna on an empty stomach out of habit, keep them separate and take Ferric Citrate with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Ferric Citrate products can differ — so check the directions on your own box. This is about absorption, not an interaction.

Does Ferric Citrate interact with any supplements?

Yes. Ferric Citrate has documented interactions with 17 supplements in our database — Rna And Dna is not one of them. The Ferric Citrate interaction page linked on this page lists every one, ranked by severity.
