Types of Calcium Supplements

Types of Calcium Supplements

Various types of calcium compounds act as supplements with varied absorption characteristics, including the following:

Calcium Carbonate

The most commonly used form of calcium for supplementation.

Calcium carbonate has the greatest elemental calcium content and requires stomach acid for effective absorption. It is best to take it with meals for optimal absorption.

Also, it acts as an antacid to relieve heartburn, acid indigestion, and upset stomach.

Calcium Citrate

This form is more easily absorbed by the body, making it a suitable option for individuals with low stomach acid or those taking acid-reducing medications. 

It can be taken with or without food.

Other forms

Calcium lactate, calcium gluconate, and calcium phosphate are less common forms of calcium supplements. 

They contain lower amounts of elemental calcium and may require larger doses to achieve the desired intake.

As compared to other forms, calcium carbonate has a higher chance of deposition in soft tissues, leading to blockage when taken excessively, especially in the absence of magnesium, phosphorus, vitamin K and D.
