Calcium citrate

physical science Maturity 11-13 Next article →

Calcium citrate is a type of salt. It is made from citric acid. People use it as a food additive. This means it is added to food to help it. It can act as a preservative to keep food fresh. It can also add flavor.

This salt is also used in health supplements. These pills help people get more calcium. Calcium is a part of this salt. In one form, it makes up 24.1% of the mass. In another form, it makes up 21.1%. One form is found in nature. It is a mineral called Earlandite.

Making this salt is a set of steps. First, a fungus makes citric acid. Then, limewater is added to the liquid. This makes the calcium citrate form a solid. Workers filter the solid and wash it.

Calcium citrate is easy for the body to use. This is called bioavailability. It means the body can take in the calcium well. It does not change the acid in your stomach. Some other salts can make the stomach produce too much acid. This can be hard to digest. But calcium citrate is a gentler choice for many people.
