Strontium

Strontium is a mineral that is not classified as essential for the human body.

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):

Science Ratings	Health Concerns
	Osteoporosis
	Dental cavities
Reliable and relatively consistent scientific data showing a substantial health benefit. Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit. For a herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support and/or minimal health benefit.

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.¹

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.
