Ingredient Compatibility

Known Interactions

COPPERUse CautionAbsorption Competition

Zinc competes with Copper for absorption via metallothionein binding. High zinc supplementation (>40mg) without copper can induce copper deficiency. If combining, maintain a Zn:Cu ratio of 8-15:1.

COPPER GLUCONATEUse CautionAbsorption Competition

Zinc and Copper compete for intestinal absorption. Maintain Zn:Cu ratio of 8-15:1 to prevent copper deficiency from zinc supplementation.

IRONUse CautionAbsorption Competition

Iron and Zinc compete for the DMT1 transporter when taken as inorganic salts at high doses. At supplemental doses (>25mg each), absorption of both is reduced 30-50%. Use chelated forms or separate doses.

CALCIUMNoteAbsorption Competition

High-dose Calcium (>600mg) can reduce Zinc absorption by 30-50%. Consider separating doses or using chelated zinc (zinc bisglycinate) for better absorption.

FOLIC ACIDNoteAbsorption Competition

High-dose Folic Acid may reduce Zinc absorption by forming insoluble complexes. At standard supplemental doses this effect is minimal, but consider in prenatal formulations with high folate.
