HelloPharmacist Scorecard of Copper 3 mg by NaturesPlus

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 12, 2026

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: copper, a mineral your body needs for nerve function, bone strength, and iron handling. NaturesPlus supplies 3 mg per tablet.

The inactive ingredients are dicalcium phosphate, microcrystalline cellulose, stearic acid, cellulose, magnesium stearate, and pharmaceutical glaze — typical binders and fillers.

Does it work?

Strong evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Strong

Clinical evidence supports at least one of this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Copper nutrient for bone and blood health.
  • We looked for evidence on: Copper deficiency, Osteoporosis, Wound healing, Red blood cell formation, Elastin formation, Connective tissue health.
  • The strongest evidence on file: Copper is rated "Likely Effective" for Copper deficiency (Natural Medicines).
  • Also on file: Copper is rated "Insufficient Reliable Evidence To Rate" for Osteoporosis, Wound healing.

Copper is likely effective for treating copper deficiency, which can show up as anemia or nerve problems if you don't get enough. For Alzheimer disease, the evidence suggests it's possibly ineffective.

For acne, chemotherapy-related anemia, and brain tumors, we don't yet have enough reliable evidence to say whether copper helps.

The evidence, ingredient by ingredient Copper

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Copper at normal supplement doses is well tolerated, but excess copper can become toxic. Rare cases of contact dermatitis (skin irritation) from copper have been reported.

Some studies show people with diabetes have higher blood copper levels than those without, though it's unclear whether elevated copper contributes to diabetes developing or worsening. In pregnancy, copper is needed and standard amounts are considered likely safe, but avoid high-dose supplements without medical guidance.

Recommended amounts during lactation are considered likely safe as well.

Side effects, ingredient by ingredient Copper

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Copper.
  • The most serious interaction on file is rated Moderate.
  • For scale: 31 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Check with us before taking this if you use penicillamine (Cuprimine, Depen) — copper can reduce how much your body absorbs. Also flag it if you're on oral contraceptive drugs, since they raise your blood copper levels.

The bottom line

Scorecard at a glanceFully disclosed formula with clinical evidence supporting its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This supplement makes sense if you have a diagnosed copper deficiency or eat a diet low in copper-rich foods. If you take penicillamine or hormonal birth control, talk to your pharmacist first — timing or monitoring may matter.

Anyone with diabetes should discuss copper supplementation with their doctor.

Formula

Copper aids in the formation of bone, hemoglobin and red blood cells; it works in balance wit zinc and vitamin C to promote the formation of elastin, and important skin protein. It is a vital component of several enzymes involved in energy production, immune system function, red blood cell formation and connective tissue maintenance. Copper promotes cardiovascular health, nervous system function, cellular metabolism and iron absorption.

Copper2 drug types · 31 drugs

Penicillamine (Cuprimine, Depen)

Theoretically, taking copper with penicillamine might decrease the absorption of penicillamine; separate dosing by at least 2 hours.
Copper chelates penicillamine, which decreases its absorption and may reduce its clinical effects.

Likelihood Probable Evidence D
Contraceptive Drugs

Theoretically, taking copper with contraceptive drugs might increase the levels and toxic effects of copper.
A meta-analysis of clinical studies suggests that chronic use of oral contraceptives increases serum copper levels by a mean of 57 mcg/dL. In most people, this resulted in levels above the normal reference range for copper.

Copper 3 mg by NaturesPlus: Common Questions

Does Copper 3 mg by NaturesPlus interact with any medications?
Yes. Based on its ingredients, Copper 3 mg has a known interaction with 31 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Copper 3 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Does copper actually work for Alzheimer disease?
No — the evidence we have suggests it's possibly ineffective. Copper isn't considered a treatment for Alzheimer disease.
Is it safe to take during pregnancy?
Copper is needed in pregnancy and standard amounts are considered likely safe. Don't take high-dose supplements, though, without checking with your doctor first.
What side effects might I notice?
Contact dermatitis (a rash or skin irritation) is rare. Some people with diabetes have been found to have higher blood copper levels, though we don't know yet if supplemental copper worsens blood sugar control.
Why does this interact with birth control?
Oral contraceptives raise your blood copper levels — typically by about 57 mcg/dL. In most people this pushed levels above normal, but it's something to monitor if you're on the pill.
Can I take this with penicillamine?
Copper binds to penicillamine and stops your body from absorbing it properly, which weakens the drug. If you must take both, space them at least 2 hours apart. Talk to your doctor first.
