HelloPharmacist Scorecard of Cu-1.5 by Bio-Tech Pharmacal

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.

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.

Cu-1.5 is a single-ingredient supplement: copper. This is an essential mineral your body needs for making red blood cells, keeping your immune system working, and building connective tissue.

The capsule also contains microcrystalline cellulose and a vegetable-based capsule material.

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 supplementation and nutrient support.
  • We looked for evidence on: Copper deficiency, Immune function, Red blood cell formation, Bone health.
  • The strongest evidence on file: Copper is rated "Likely Effective" for Copper deficiency (Natural Medicines).

Copper is likely effective for treating copper deficiency—if your doctor has confirmed you're deficient, this supplement addresses that. For Alzheimer's disease, the evidence suggests it's possibly ineffective.

For acne, chemotherapy-related low red blood cell count, and brain tumors, we don't have enough reliable evidence to rate whether it works.

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 from food and standard supplement doses is well tolerated in most people, but excess copper can be toxic. Rarely, contact dermatitis (skin irritation from direct contact) has been reported.

There's evidence that people with diabetes tend to have higher blood copper levels than others, though it's unclear whether elevated copper makes diabetes worse. In pregnancy, copper is needed for fetal development, but stick to recommended amounts and avoid high-dose supplements unless your doctor advises otherwise.

Recommended amounts during lactation are considered safe.

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 your pharmacist if you take penicillamine—a Moderate interaction requires separating doses by 2 hours. Also flag oral contraceptive drugs (birth control), where a Minor interaction may increase copper levels and effects.

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.

Cu-1.5 is straightforward for copper deficiency replacement. If you take penicillamine or birth control pills, check with your pharmacist first—timing matters with penicillamine, and the pill may already be raising your copper levels.

Talk to your pharmacist before starting, especially if you have diabetes or take any regular medications.

Each ingredient & the kinds of drugs it affects

For each ingredient in Cu-1.5 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-1.5 by Bio-Tech Pharmacal: Common Questions

Does Cu-1.5 by Bio-Tech Pharmacal interact with any medications?
Yes. Based on its ingredients, Cu-1.5 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-1.5 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 this help with Alzheimer's disease?
No. The evidence suggests copper is possibly ineffective for Alzheimer's, so we wouldn't recommend it for that reason.
Is copper safe during pregnancy?
Copper is needed during pregnancy and recommended amounts are considered likely safe. But avoid high-dose supplements unless your doctor directs otherwise; stick to what's advised for your prenatal care.
Can copper cause skin problems?
Rarely, contact dermatitis (itchy or irritated skin) from copper has been reported, usually from touching copper-containing objects. Taking the supplement by mouth is unlikely to cause this, but watch for any new rashes.
Is this safe if I have diabetes?
People with diabetes often have higher blood copper levels naturally. It's unclear whether extra copper makes diabetes worse, so talk to your doctor or pharmacist before adding this supplement.
What happens if I take too much?
Excess copper can be toxic. Stick to the dose on the label and don't take more without medical guidance. If you accidentally take too much, contact poison control or your doctor.
