What is Strontium?

Strontium is a silvery metal found naturally as a non-radioactive element. About 99% of the strontium in the human body is concentrated in the bones.

Several different forms of strontium are used as medicine. Scientists are testing strontium ranelate to see if it can be taken by mouth to treat thinning bones (osteoporosis). Radioactive strontium-89 is given intravenously (by IV) for prostate cancer and advanced bone cancer. Strontium chloride hexahydrate is added to toothpaste to reduce pain in sensitive teeth.

Strontium chloride is the most common form of strontium found in dietary supplements. People use supplements for building bones. But there isn't much scientific information about the safety or effectiveness of strontium chloride when taken by mouth.

Effective for...

  • Bone pain related to bone cancer. Research shows that a special prescription form of strontium (strontium-89 chloride) given intravenously (by IV) reduces pain from metastatic bone cancer.
  • Sensitive teeth. Research shows that using strontium chloride with strontium acetate in toothpaste relieves pain in sensitive teeth. Brushing twice daily seems to work best.

Possibly Effective for...

  • Osteoporosis ("bone thinning"). Some evidence shows that taking strontium ranelate by mouth appears to reduce the risk of vertebral and nonvertebral fractures and increase bone mass postmenopausal women with osteoporosis.
  • Prostate cancer. Some research shows that giving a special prescription form of strontium (strontium-89 chloride) intravenously (by IV) slows the growth of prostate cancer that is resistant to treatment and also relieves pain.

Insufficient Evidence to Rate Effectiveness for...

  • Osteoarthritis. Early research suggests that taking strontium ranelate by mouth for 3 years improves back pain and helps prevent spinal osteoarthritis from becoming worse in some postmenopausal women.
  • Dental cavities.
  • Other conditions.
More evidence is needed to rate the effectiveness of strontium for these uses.

Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
