Ingredient Information
Summary
Calcium Citrate is a form of calcium, an essential mineral that contributes to normal bone and teeth maintenance. It’s more easily absorbed by the body compared to other forms of calcium, making it a popular choice for those needing a supplement. Calcium Citrate is particularly beneficial for individuals who have low stomach acid, such as older adults, or those who have difficulty absorbing calcium from food. It can also be useful for people who are lactose intolerant or follow a vegan diet, as they may not get enough calcium from their diet alone.

What Is Calcium Citrate?
Calcium Citrate, also known as tricalcium dicitrate or E333, is a calcium salt of citric acid with the empirical formula Ca3(C6H5O7)2. It is classified as a mineral supplement and is commonly found in a white, crystalline powder form. Calcium Citrate is typically manufactured by neutralising citric acid with calcium hydroxide or calcium carbonate. It is often used in dietary supplements due to its high bioavailability, meaning it is easily absorbed by the body. Calcium Citrate contributes to normal muscle function and the maintenance of normal bones and teeth.
