What does it do?
Strontium is a mineral that is not classified as essential for the human body.
There is research that strontium has been shown to promote strong, osteoporosis-resistant bones,1 lessen the risk of
dental cavities,2 and reduce the pain of bone
lesions that occasionally develop in association with certain cancers.3 The type of strontium used as a
supplement is not the radioactive type.
Where is it found?
Strontium is widely distributed throughout nature. Strontium levels in the soil determine
how much strontium will be in the foods grown in particular areas. Areas with strontium-rich
soils also tend to have higher levels of strontium in the drinking water.
Strontium has been used in
connection with the following conditions (refer to the individual
health concern for complete information):
Who is likely to be deficient?
Strontium is not an essential mineral, so deficiencies are not seen with this mineral.
How much is usually taken?
No recommended intake levels have been established for strontium, since it is not
considered essential for humans. However, preliminary research in humans suggests that
600–1,700 mg of strontium, taken as a supplement in the form of strontium salts, may
increase bone mass in the vertebrae of people with
osteoporosis.4
Are there any side effects or interactions?
No consistent toxicities from strontium supplements have been reported.
At the time of writing, there were no well-known drug interactions
with strontium.
