What is Strontium?
Strontium (Sr) is a chemical element that is very similar to calcium. Although it is considered a trace element (a substance needed only in small amounts by the body to maintain health), it is actually an abundant chemical found in the soil, rocks as well as in seawater. This metal substance is silvery, soft, alkaline, and non-radioactive. It easily reacts with air and water, so in nature it often occurs combined with other elements or compounds to form more stable compounds such as carbonate strontianite (SrCO3) and sulfate mineral celestite (SrSO4).
In the environment, there are strontium compounds that are water soluble and those that are water-insoluble. Water ...view middle of the document...

What are Strontium Side Effects?
Strontium compounds that are prescribed and available as injections are safe as long as they are used under medical supervision. However, side effects of strontium ranelate may include headache, stomach pain and diarrhea. Very high doses of strontium for osteoporosis may damage the bones, but there are not enough studies to prove this.
Strontium supplements are generally safe when taken in recommended doses and toos containing strontium have gained FDA approval for safety.
Special warnings include:
For pregnant and breastfeeding women – strontium toothpaste is safe, but experts warn against using strontium supplements as well as radioactive strontium.
The safety of strontium supplements for children has not been established.
Individuals with Paget's disease of the bones seem to absorb more strontium than other people, but the health effects are not known.
Strontium must be avoided by people with kidney diease since it may accululate in large amounts when not adequately excreted. Likewise, people who have other serious conditions such as heart disease must avoid its use.
