How does Strontium work?

A special form of strontium called strontium ranelate can increase bone formation and prevent bone loss when used in postmenopausal women with osteoporosis. It's not known if strontium contained in dietary supplements has these effects.
A radioactive form of strontium may kill some cancer cells. This type of strontium is not available in dietary supplements.

Are there safety concerns?

The forms of prescription strontium are safe when used under the supervision of a healthcare provider. Strontium ranelate might cause side effects such as stomach pain, diarrhea, and headache in some people. But there's not enough information to know if the form of strontium contained in dietary supplements is safe.

There is some concern that very high doses of strontium might damage the bones.

Strontium supplements might not be safe for children.

Do not use strontium if:
  • You are pregnant or breast-feeding.
  • You have kidney problems.
  • You have a history of blood clots.
  • You have Paget's disease of the bones.
