The currently available evidence does not demonstrate the benefits of strontium formulations that can be obtained for oral supplementation over the counter. Though clinical evidence is lacking, the available preclinical evidence suggests that strontium could improve bone strength (preventing bone loss and fractures related to bone loss).[1][2][3]
When used as an additive to toothpaste or creams and applied topically, strontium has been shown clinically to reduce dental and skin sensitivities or irritation.[4][5][6][1][7][8][9]
