  • Why Strontium Is Not Advised for Bone Health

     · (Strontium may remain in the bones for as long as 7–10 years after the last dose.) Strontium has a chemical similarity to calcium and will replace calcium as the mineral in bone. Because strontium atoms are heavier than calcium atoms, swapping some of the calcium atoms with strontium atoms will make the bone mineral density appear to increase.
