Calcium Citrate Malate vs. Calcium Carbonate: What's the Difference?
Edited by Harlon Moss || By Aimie Carlson || Published on January 11, 2024
Calcium citrate malate is a water-soluble calcium supplement, better absorbed in low acid conditions, whereas calcium carbonate, less soluble, requires stomach acid for absorption.
Key Differences
Calcium citrate malate is a compound combining calcium, citric acid, and malic acid, known for its high bioavailability. Calcium carbonate is a basic calcium salt, found in chalk, limestone, and marble.
Calcium citrate malate is more easily absorbed in the body, especially in people with lower stomach acid. Calcium carbonate requires more stomach acid for absorption, making it less suitable for older adults or those on acid reducers.
Calcium citrate malate is often preferred in dietary supplements due to its higher bioavailability and gentler impact on the stomach. Calcium carbonate, while common in supplements, can cause digestive discomfort in some individuals.
Calcium citrate malate remains effective even in low-acid conditions, beneficial for individuals with reduced stomach acidity. Calcium carbonate is most effective when taken with food, as it relies on stomach acid for absorption.
Beyond supplements, calcium carbonate is widely used in industrial applications, including as a building material and antacid. Calcium citrate malate is primarily used in nutritional supplements due to its absorption properties.
