Because the elements are chemically similar, the stable strontium isotopes might not pose a significant health threat — in fact, the levels found naturally may actually be beneficial (see below).

Brighter atoms are strontium and darker ones are titanium.

From strontium onward, the alkali earth metals become denser with increasing atomic mass.

Half the increase in bone density (measured by X-ray densitometry) is discounted because strontium has greater atomic density than calcium, while the other half is a true increase in bone mass.
