I read somewhere about strontium being important for bones, so I was looking into supplementation. Found this article. It has me scared of strontium supplements. http://saveourbones.com/strontium-demistyfied/ I don't know if the article is true. The author appears to think she is an expert and wants to sell information. However, on WebMD they say "Strontium is chemically similar to calcium" so I think it may be bad to supplement like calcium seems to be.
