Copper-deficiency anemia support
This is anecdotal, and there isn't strong clinical evidence that it works for everyone.
Copper is required for iron metabolism, connective tissue formation, and nervous system function. Deficiency most commonly occurs after prolonged high-dose zinc use or malabsorption.
Form: Copper bisglycinate
Typical dose studied: 1–2 mg/day when indicated
Timing: With food; separate from high-dose zinc supplements
Only supplement if deficiency risk exists. Do not combine with high-dose zinc without balancing copper.
Pairs well with:
Only relevant if taking zinc at a high dose or long-term — copper needs may increase — Chronic high-dose zinc intake can impair copper absorption and status over time.
✓ Well-established
Interacts with: Separate from high-dose zinc
Already taking it? Assess zinc-to-copper balance. Wilson disease (a rare genetic copper-accumulation disorder) is a real but very rare contraindication -- copper supplementation would directly worsen it.
