This ingredient serves a specialized role in cosmetic formulations, contributing to the overall efficacy, stability, or sensory experience of the final product.
Ingredient Compatibility
Known Interactions
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.
Zinc and Copper compete for intestinal absorption. Maintain Zn:Cu ratio of 8-15:1 to prevent copper deficiency from zinc supplementation.
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.
High-dose Calcium (>600mg) can reduce Zinc absorption by 30-50%. Consider separating doses or using chelated zinc (zinc bisglycinate) for better absorption.
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.
