Additional Information

Bone meal is a natural source of Calcium Phosphate, a composition of Calcium and Phosphorus known as hydroxyapatite. Hydroxyapatite, found in teeth and bones, confers rigidity to these structures and is wellabsorbed from the digestive tract. Phosphorus is necessary for the production of bone tissue and plays an integral role in the maintenance of the body’s acid-base balance.
