What It Does
Calcium citrate is the calcium salt of citric acid, formed by reacting citric acid with a calcium source such as calcium carbonate. Unlike calcium carbonate, it is notably more soluble in water and does not require an acidic environment for absorption or dissolution, making it a preferred calcium source in formulations where neutral to mildly acidic pH is maintained. In cosmetic and functional water applications, its fine powder form disperses readily, contributing a subtle mineral character and ionic complexity that mimics the mouthfeel profile of natural calcium-rich spring waters without introducing turbidity or off-notes.

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