@sophies
was I advised by a doctor?
Well, that is an interesting story. I was seeing an endocrinologist; started an osteo drug that was having no effect except to make me ill. The endo had told me about a new drug in Europe with great results; I researched it and found that all it was was strontium joined to an additive that could be patented.
So I dropped the osteo drug; began the strontium citrate and viola no side effects, and my first better dexa. Confessed to my endo; he called a bunch of other experts and said "change nothing". Every dexa was better, no fractures no side effects; that endo released me saying "you don't need me anymore and change nothing".

No, the endo didn't care about the 10 % over read on dexa; he and I both could do the math easily. Plus, now we have TBS and REMS and neither overreads strontium.

Bone is always going to degrade if you stop calcium or lose hormones or in this case stop strontium. I did stop for awhile, and I lost a very small percent of my bone density not even the 10% that I thought it was overreading.

Well, all the research says that strontium is safe and since it is in the ground water of most of the world, most of its food and sometimes higher in ground water than the dose which I take, I think that history shows it is safe with no pockets of cardio problems etc showing up in population studies. There have been instances of short, thicker boned people; what I read was that they were treated with calcium. Can't find that link but I will keep looking; I saw it years ago.

The research on stontium via citrate also shows safety as does the research on strontium via ranelate. There is one population study on strontium via ranelate that seemed to show some cardio problems, but that study included people with cardio problems so duh. Several countries redid the study over a period of several years and found no cardio problems or any other dangerous side effects.

So the calcium /strontium ratio is important....always more calcium.
