What does it do? The mineral, strontium, is not classified as essential for the human body, although it has been shown in research 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.
Strontium has been used in connection with the following conditions (refer to the individual health concern for complete information):

and relatively consistent scientific data showing a substantial health benefit. Contradictory, insufficient, or preliminary studies

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
