No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Copper and Progesterone 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.

Copper and Progesterone

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 Progesterone and Copper 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.

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.

How we checked

Why No Interaction Is Listed for Progesterone

Interactions in our licensed database are recorded against drug classes, not just single drug names. Progesterone is filed under 3 classifications — including topical drugs, cytochrome p450 3a4 (cyp3a4) substrates. Copper has documented interactions with 2 drug classes — the most serious being penicillamine (cuprimine, depen) (moderate) and contraceptive drugs (minor) — and none of Progesterone’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

Keep it in perspective

What to actually watch for

What Copper Itself Has Been Linked To

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

  • Numbness or tingling / A skin rash Additional detail

    “Contact dermatitis caused by copper has been reported rarely. A case report describes a 5-year-old male who developed recurrent fingertip dermatitis and a positive skin test to copper after playing with toy cars made with a copper-containing alloy.”

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

Special populations

Copper in Pregnancy & Breastfeeding

Pregnancy Likely Safe

When used orally in doses exceeding the UL. Higher intake can cause liver damage.

Lactation Likely Safe

When used orally and appropriately. Copper is safe in amounts that do not exceed the tolerable upper intake level (UL) of 8 mg daily for those 14-18 years of age or 10 mg daily for those 19 years and older.

Everything else you take

See Every Supplement That Interacts With Progesterone

This page covers Copper only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Progesterone page lists 126 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Grapefruit (major), St. John's Wort (major), Acacia Rigidula (moderate), Adrafinil (moderate) and African Wild Potato (moderate).

By severity: 2 major · 91 moderate · 33 minor.

From our pharmacist’s overview on the Progesterone page

“Many people take progesterone (Milprosa) to support a pregnancy during fertility treatment or as part of hormone therapy, which is exactly when St. John's wort for mood or a morning glass of grapefruit juice can feel harmless.”

About Copper

What is Copper?

  • Preventing or treating copper deficiency
  • Supporting red blood cell formation
  • Bone and connective tissue health
  • Immune support
  • Antioxidant defense
  • Balancing high zinc intake

Copper is an essential trace mineral your body needs in small amounts for making red blood cells, supporting nerves and bones, and helping enzymes work. Most people get enough copper from food, and supplements are mainly useful for diagnosed deficiency. Too much copper can be harmful, so do not take high doses without medical advice.

Copper is an essential trace mineral (element Cu) · Tablets, capsules, multivitamin/mineral products; forms include copper gluconate, copper sulfate, copper citrate, and cupric oxide

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

Copper: dosing

There is no single "best" supplement dose for everyone. The amount your body needs each day is small and is usually met through diet. If you take a supplement, it is best to use the amount on the product label or the amount your doctor recommends.For diagnosed copper deficiency, a doctor will choose the right dose and monitor your levels. Do not try to self-treat a suspected deficiency with high doses.Because copper can be harmful in excess, avoid taking more than the labeled amount, and avoid stacking several products that all contain copper. A pharmacist can help you check the total copper in your supplements.

About Progesterone

What Is Progesterone Used For?

Brand name: Milprosa

Progesterone capsules (including Prometrium) are used to prevent endometrial hyperplasia (abnormal thickening of the uterine lining) in postmenopausal women with a uterus who are taking estrogen, and to treat secondary amenorrhea (missed periods not caused by pregnancy).

Progesterone injection is indicated for amenorrhea and abnormal uterine bleeding caused by a hormonal imbalance. Crinone vaginal gel is used as part of Assisted Reproductive Technology (ART) for progesterone supplementation or replacement, and Crinone 4% is also indicated for secondary amenorrhea. Vaginal inserts — including Endometrin and other progesterone vaginal insert products — are used to support embryo implantation and early pregnancy as part of an ART treatment program for infertile women.

Most-Reported Side Effects for Progesterone

From FAERS, the FDA’s public side-effect reporting system (22,803 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Interactions in our licensed database are recorded against drug classes. Progesterone is filed under 3 classifications, and Copper has documented interactions with 2 drug classes — none of Progesterone's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Copper interact with any other medications?
Yes. Copper has 31 documented drug interactions in our database — Progesterone is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Progesterone interact with any supplements?
Yes. Progesterone has documented interactions with 126 supplements in our database — Copper is not one of them. The Progesterone interaction page linked on this page lists every one, ranked by severity.
