Calcium citrate is a white, odorless, fine powder with a neutral taste. It is usually supplied as the tetrahydrate (CAS 5785-44-4) with about 21% calcium. It dissolves only slightly in water, but its neutral taste makes it easy to use in food. In the EU, it carries the E number E333.
Food and beverage producers use it to fortify juices, plant-based milks, cereals and dairy alternatives, because it adds calcium without a chalky taste. It also works as an acidity regulator, sequestrant and firming agent. Producers of nutritional products and pharmaceutical companies use it in tablets, capsules and powders, where regulations in each market govern its use.
Compared with Calcium gluconate, calcium citrate offers more than twice the calcium content. Calcium acetate and Magnesium citrate are related mineral salts for other applications.
