HelloPharmacist Scorecard of Copper Bisglycinate by Thorne

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 11, 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.

Copper Bisglycinate is a single-ingredient product — it contains copper bound to the amino acid glycine, a form designed for better absorption. Copper is an essential mineral your body needs for nerve function, immune health, and energy production.

The capsule also holds microcrystalline cellulose, hypromellose, and leucine 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
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 for foundational health.
  • We looked for evidence on: Copper deficiency, Immune function, Bone health, Connective tissue support.
  • The strongest evidence on file: Copper is rated "Likely Effective" for Copper deficiency (Natural Medicines).

Copper supplementation is likely effective for treating copper deficiency, which can happen from long-term parenteral nutrition or certain absorption disorders. For Alzheimer disease, the evidence suggests copper is possibly ineffective — it hasn't been shown to help.

The data we hold doesn't establish whether copper works for acne, chemotherapy-related anemia, or brain tumors, so claims about those uses are not supported.

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 amounts found in food and standard supplements is well tolerated. High doses can be toxic, so stick to recommended amounts and avoid megadoses unless your doctor directs it.

Copper is needed during pregnancy, but stay within recommended intake and don't take high-dose supplements without medical advice. A rare side effect is contact dermatitis from copper exposure; one case report describes a young child who developed fingertip rashes after playing with copper-containing toy cars.

In a small trial of topical copper sulfate on infants, a few children developed superficial burns, though this is topical application, not oral supplements. People with diabetes tend to have higher copper levels in their blood than those without, though it's unclear whether elevated copper worsens diabetes itself.

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 your medications if you take penicillamine — copper can block its absorption and reduce its effectiveness. Also mention birth control pills to your pharmacist, since they can raise your copper levels.

For each ingredient in Copper Bisglycinate 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.
