The most commonly used calcium salt of citric acid is tricalcium dicitrate tetrahydrate, hereinafter referred to as tricalcium citrate. 
In some countries such as USA, tricalcium citrate is simply denominated calcium citrate. 
Tricalcium citrate is produced by complete neutralisation of citric acid with a high purity calcium source such as calcium hydroxide or calcium carbonate.

With its high calcium content of 21%, tricalcium citrate is the most economic calcium salt among the commonly used organic calcium salts.

Tricalcium citrate is supplied as a white, odourless, crystalline powder or fine powder. 
Tricalcium citrate is slightly soluble in water and freely soluble in diluted hydrochloric acid. 
In contrary to other salts, tricalcium citrate is better soluble at lower temperatures (so-called "inverse solubility"). 
Tricalcium citrate is practically insoluble in alcohol.

During heat treatment, Tricalcium citrate is less reactive than other calcium salts due to its inverse solubility. 
With regard to its significantly better bioavailability, tricalcium citrate is preferred over inorganic calcium sources such as calcium carbonate or calcium phosphate.

Tricalcium Citrate (TCC) is produced by complete neutralization of citric acid with a calcium source.
With its high calcium content of 21 %, TCC is the most economic calcium salt among the commonly used organic calcium salts. 
Due to its functional properties, high bioavailability and health benefits, TCC is widely used as a calcium source in foodstuffs, nutrional supplements, dietary products and pharmaceutical applications.
Some calcium phosphates derive from phosphate rocks, calcium from plant sources, and ammonia.

These can be considered vegan. 
Most of the time, however, calcium phosphates are made from ground animal bones.

Calcium phosphate aids in cell functioning and plays a vital role in many different body processes, including bone growth and energy production.

Tricalcium phosphate is effective as a nutritional supplement because Tricalcium citrate is readily absorbed in the body. 
However, there is little evidence to show Tricalcium citrate is more effective than other calcium supplements, in particular, those containing citrate and carbonateTrusted Source.

Tricalcium citrate also has many other uses. 
Tricalcium citrate is found in many household items, including baby powder, toothpaste, and antacids. 
A variety of industries use Tricalcium citrate. 
For example, the biomedical sector uses Tricalcium citrate to make cement or composite to repair bones

Tricalcium citrate is an essential mineral that supports multiple systems throughout the body. 
You need to maintain adequate calcium levels in order for your heart, nervous system, and muscles to function properly.

When you don't get enough calcium from outside sources, such as food or supplements, your body dips into the calcium bank stored in your bones to keep blood levels up. 
Over time, pulling calcium from your bones weakens them and increases the risk of fracture.

Beyond bones, additional possible benefits of calcium supplementation include improvements in blood pressure and weight loss. 
Here's what the research says.

Blood pressure: Although the underlying mechanism is unclear, calcium has been associated with reducing blood pressure in multiple studies.
However, there are rising concerns that excessive calcium through supplements may harden arteries and pose cardiovascular risks.
Weight loss: When people are placed on low-calorie diets, studies show that adding calcium and vitamin D supplements improves their rate of fat loss while preserving muscle and bone mass.
As with many dietary supplements, taking more calcium than we need probably does more harm than good. 
Instead of blindly adding calcium citrate, only purchase a supplement if you know you aren't getting enough from food and beverages.
