HelloPharmacist Scorecard of CU Copper 3 mg by NutraBio

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.
  • “Copper” is listed as a grouped ingredient — the label gives one combined amount (3 mg) without saying how much of each component you get.

CU Copper 3 mg contains one active ingredient: Albion Copper Bisglycinate Chelate, a chelated form of copper designed for absorption. Copper is an essential mineral your body needs for iron metabolism, connective tissue, and nervous system function.

The capsule also contains rice flour and a vegetable-based capsule shell as inactive ingredients.

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

This product doesn't appear to be marketed for a specific use, so we graded Copper's overall clinical evidence instead.

Strong

Strong clinical evidence supports Copper for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Copper deficiency — rated "Likely Effective" (Natural Medicines).

Copper supplementation is likely effective for treating copper deficiency—the clearest use for this product. For Alzheimer disease, the evidence suggests it's possibly ineffective.

For acne, chemotherapy-related anemia, and brain tumors, we don't have enough reliable evidence to rate whether it works. Talk with your doctor about whether supplementing makes sense for your specific situation.

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 in food and standard supplement amounts is safe for most people, but excess copper can be toxic, so stick to recommended doses. Copper is needed during pregnancy and is likely safe at normal levels, though the data also suggests staying within recommended amounts and avoiding high-dose supplements unless your doctor advises otherwise.

The same caution applies to lactation—recommended amounts are considered acceptable. Rarely, contact dermatitis (skin irritation) from copper has been reported, and there's observational evidence that people with diabetes tend to have higher blood copper levels, though it's unclear whether elevated copper contributes to diabetes development or worsening.

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.

If you take penicillamine, separate your copper dose by at least 2 hours to avoid reducing penicillamine's absorption—this is a moderate interaction. If you use oral contraceptive drugs (birth control pills), be aware that copper can increase to higher-than-normal blood levels; discuss this with your prescriber.

Check your exact medications with the tool on this page to be sure.

The bottom line

Scorecard at a glanceFully disclosed formula with strong clinical evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

This supplement is straightforward for someone with a copper deficiency. If you take penicillamine or hormonal birth control, check with your pharmacist first—these combinations need some attention.

Stay within the recommended dose and talk to your doctor before using a high-dose copper supplement, especially if you're pregnant, breastfeeding, or have diabetes.

For each ingredient in CU Copper 3 mg with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.

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.

CU Copper 3 mg by NutraBio: Common Questions

Does CU Copper 3 mg by NutraBio interact with any medications?
Yes. Based on its ingredients, CU 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?
CU 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.
Is copper safe to take if I'm pregnant or breastfeeding?
Copper is likely safe during pregnancy and lactation at recommended amounts, since your body needs it. The caution is to stay within those recommended doses and avoid high-dose supplements unless your doctor advises it. If you're pregnant or nursing, talk with your doctor or pharmacist about the right amount for you.
What is Albion Copper Bisglycinate Chelate?
It's a form of copper that's been bonded to an amino acid to help your body absorb it better. Chelated forms like this are designed to be easier for your digestive system to take up than plain copper salts.
Can copper help with Alzheimer disease?
The evidence suggests copper is possibly ineffective for Alzheimer disease, so it's not a reliable treatment for that condition. If you're interested in supplements for cognitive health, talk with your doctor about what the science actually supports.
What if I have diabetes—should I be cautious about copper?
People with diabetes do tend to have higher copper levels in their blood than those without, but we don't know yet whether elevated copper contributes to diabetes or makes it worse. Given this uncertainty, it's worth discussing copper supplementation with your doctor if you have diabetes.
Are there any side effects I should watch for?
Contact dermatitis (skin irritation from copper contact) has been reported rarely. At standard supplement doses, side effects are uncommon, but taking more than recommended amounts can be toxic. Stick to the label dose and report any unusual symptoms to your pharmacist.
