HelloPharmacist Scorecard of Copper Bisglycinate 8 mg by Dr. Mercola

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.

This product contains one active ingredient: copper (as copper bisglycinate), delivering 8 mg per tablet. Copper is an essential mineral your body needs for several functions, including energy production, connective tissue formation, and iron metabolism.

The inactive ingredients are microcrystalline cellulose, ascorbyl palmitate, silicon dioxide, tapioca maltodextrin, sunflower lecithin, palm oil, and guar gum.

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.
  • We looked for evidence on: Copper deficiency.
  • The strongest evidence on file: Copper is rated "Likely Effective" for Copper deficiency (Natural Medicines).

Copper is likely effective for treating copper deficiency — the clearest use for a supplement like this. For Alzheimer disease, the evidence suggests it may be ineffective.

For acne, chemotherapy-induced anemia, 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 supplements is generally well tolerated in recommended amounts. However, excess copper can be toxic, so don't exceed advised doses.

The data shows copper is needed during pregnancy, but stick to recommended amounts and avoid high-dose supplements without medical guidance. Rare side effects include contact dermatitis from copper exposure.

Additionally, people with diabetes tend to have higher blood copper levels than those without diabetes, 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.

Before you take this, double-check if you're on penicillamine (Cuprimine, Depen) — copper will interfere with how well it works, and you'll need to time your doses carefully. Also flag any oral contraceptive you're using, since copper levels may climb while you're on the pill.

Check your own medication Run your meds through the checker above

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 or are at risk for copper deficiency. If you take penicillamine or oral contraceptives, check your exact medications with the tool on this page before starting.

Stick to the recommended dose — more is not better with copper. Chat with your pharmacist if you have diabetes or any concerns about your copper intake.

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.
