I was taking Strontium for about two years and recommending it to everyone I knew. My Dexa scans were improving, and I was able to stay off osteo drugs completely. However, my hair started falling out in patches. At first, a possible connection to Stronium didn't even occur to me. Then I came across an article in The British Medical Journal saying that Strontium may cause alopecia. Here's the link: http://www.bmj.com/content/338/bmj.b1494.extract.
Unfortunately, that diagnosis was recently confirmed in my case. I'm passing this information on to all of you just so you know. I'm sure many women who take Strontium will never have this happen, but people should know, nevertheless.
