Additionally, strontium could replace calcium within the active site of the human enzyme tissue-nonspecific alkaline phosphatase (an alkaline phosphatase involved in the control of hydroxyapatite formation and bone mineralization) and modify its configuration, as shown in a crystal structure study (Llinas et al., 2006). There is no immediate cost to the implementation of this guideline. PRODUCT SPECIFICATION.

Strontium is stored in kerosene or mineral oil to increase its shelf life and avoid reaction with water or air. Sufficient levels of calcium and vitamin D in the body can lower the amount of strontium incorporated into bones, decreasing the likelihood of adverse effects on the bones of children that have adequate calcium and vitamin D status. Reduced foetal calcium without skeletal malformations in rats following high maternal doses of a strontium salt. In fact, bone effects are more prominent in young rats than in adults, supporting the choice of the sensitive subpopulation (Storey, 1961, 1962; Svensson et al., 1985, 1987; Neufeld and Boskey, 1994).

The binding of strontium, a larger atom than calcium, and the higher carbonate content of the mineral can expand and change the structure of the apatite lattice, decrease crystal formation and growth, and increase the hydroxyapatite solubility—possibly decreasing the bone matrice stability during bone resorption processes, increasing dissolution (Skoryna, 1981; Christoffersen et al., 1997; Cabrera et al., 1999; Verberckmoes et al., 2004; Oste et al., 2005).
