What is Alcalak?

Calcium is a mineral that is found naturally in foods. Calcium is necessary for many normal functions of the body, especially bone formation and maintenance. Calcium can also bind to other minerals (such as phosphate) and aid in their removal from the body.

Alcalak is used to prevent and to treat calcium deficiencies.

Alcalak may also be used for purposes not listed in this medication guide.
