Calcium carbonate, also known as marble, is a metamorphic rock composed of coarse crystalline grains formed when chalk or limestone recrystallizes under high temperature and pressure. You can create calcium carbonate by adding carbon dioxide to calcium hydroxide solutions, or you can create it from marble.
Calcium Carbonate Properties:

How does it work:
The inorganic salt calcium carbonate is used as an antacid. In gastric secretions, it neutralizes hydrochloric acid by acting as a basic compound. As pH increases, pepsin may be inhibited. Increasing bicarbonate ions and prostaglandins may have cytoprotective effects as well.
Applications Or where it is used:
The calcium carbonate supplement is used when your diet does not contain enough calcium. The body needs calcium for healthy bones, nervous system, muscles, and heart. As an antacid, calcium carbonate helps with heartburn, acid indigestion, and upset stomach.
Calcium carbonate has three crystalline polymorphs: calcite, aragonite, and vaterite. In the carbonation process, these crystals can be produced by changing various conditions such as concentration and temperature of lime milk, introduction rate of CO2 gas, and whether or not chemicals are added.
How to use:
You should take calcium carbonate exactly as directed. Make sure you do not take it in excess, less, or more often than prescribed by your doctor. Take this medicine with food or after eating when used as a dietary supplement. Chewable tablets should be chewed thoroughly before swallowing them. Do not swallow whole chewable tablets.

Warnings and precautions while using this product:
During pregnancy, calcium carbonate should be used with caution if the benefit outweighs the risk. Studies of animals show risk, but human studies have not been conducted.
