02Restores deficiency-related anemia

03Restores low neutrophil counts

04May improve neurologic symptoms

Chemical Forms

Recommended

Copper bisglycinate
Copper gluconate
Copper citrate

Avoid

Copper oxide (poorly absorbed)

Expert Note

Soluble forms such as bisglycinate, gluconate, and citrate are generally better absorbed and easier to tolerate than copper oxide, which is less soluble and has poorer bioavailability. Chelated forms may also be gentler on the stomach.

Protocol

Amount

1-2 mg

Frequency

Once daily

When

With food; separate from high-dose zinc or iron by at least 2 hours.

Condition-Based Dosing

Low dietary intake or long-term zinc use

1-2 mg elemental copper daily— Recheck labs if used beyond 2-3 months or if zinc intake remains high.

Confirmed low serum copper or ceruloplasmin

2-4 mg elemental copper daily for 8-12 weeks, then retest and reduce once corrected— Prefer clinician guidance; severe deficiency may need different dosing or IV copper.

After normalization of copper status

Return to diet first, or continue about 0.9-1 mg/day only if intake remains low— Avoid chronic high-dose use unless a clinician is monitoring you.

Safety & Limits

Upper Safe Limit

10 mg/day (IOM UL for adults)

Cycling

Safe for continuous use

Contraindications

Wilson disease — inherited copper accumulation disorder

Active cholestatic liver disease or unexplained high copper — overload risk

Penicillamine or trientine therapy — may counteract copper-lowering treatment

Pregnancy or breastfeeding — avoid high-dose use unless prescribed

Avoid Combining With

✕High-dose zinc (>25-40 mg/day) (induces metallothionein and lowers copper absorption)
✕Iron supplements (take 2+ hours apart — mineral competition may reduce absorption)
✕High-dose vitamin C (separate by a few hours — may reduce copper availability)
✕Large bran or phytate supplements (take separately — can bind minerals)
✕Long-term acid suppressors like PPIs (reduced stomach acid may impair copper absorption)
