Calcium carbonate is many things. First of all, it's a common substance in rocks, shells and eggshells. It's also the cause of hard water. However, calcium carbonate does have some medicinal value, including acting as a calcium supplement and antacid.
Most calcium carbonate is made from pure rocks from a quarry, such as marble. While it can be used in medicine, its main use is building materials or as a part of a cement mixture. It's also used to create iron from ore and as a bridge and filter cake in drilling fluids. Another use is in paints and plastics.
When it comes to health and medicine, calcium carbonate is used as a calcium supplement, antacid or in treating patients with hyperphosphatemia. However, taking too many calcium supplements can cause calcium carbonate chest pain, a symptom of several issues such as milk alkali syndrome. Before you start taking a calcium supplement or start using calcium carbonate in cooking, check the amount of calcium in food items you're already eating. Today, many foods already contain calcium, so it is actually very easy to take too much. As with many things, a little calcium is healthy, and too much can be harmful.
Precipitated calcium carbonate has the same formula as other calcium carbonate, but its atoms are arranged differently. This makes it non-toxic, even in large doses. In fact, the FDA has listed it as safe to use in foods, so it's a great way to get your calcium supplement without taking a vitamin or calcium pill. You can purchase it from any precipitated calcium carbonate wholesale distributer if you plan on using it in large doses or pick it up from a health food store.
There is one use of a calcium carbonate that doesn't involve taking a pill or putting it in food. Magnesium calcium hydrogen carbonate thermal water is often found in spas or other luxury treatments. It helps treat skin illnesses and vein conditions, and it's even been used in therapy for people who have muscular damage.
