IRONUse CautionAbsorption Competition

Calcium inhibits both heme and non-heme iron absorption by 50-60% when taken together. These minerals compete for the same absorption pathways. Separate by at least 2 hours or formulate for different serving times.

ZINCNoteAbsorption Competition

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

MAGNESIUMNoteAbsorption Competition

Calcium and Magnesium compete for absorption at high doses. While they can be combined at moderate levels, high-dose formulations should separate them or use chelated forms.

CITRIC ACIDNotePrecipitation

High Calcium + Citric Acid can form calcium citrate precipitate in beverages, causing cloudiness or sedimentation. Manageable with proper formulation (sequestrants, pH control), but test stability.
