Thanks so much @windyshores for your response. Now that you mention it, I don't think my endocrinologist knows that about Strontium. All I said during the appointment was that it weighs more than Calcium.

I have been trying for years to strengthen my bones the natural way. I have been taking the minerals that AlgaeCal recommends, although I buy a better product from Now Foods. Last year I broke 2 bones, so I added Strontium to the minerals I was already taking. This year I broke 2 more bones, so I decided I should take medicine. My endo recommended Tymlos. I couldn't tolerate a full dose last Spring. Thanks to your posts, I learned that I could take a lower dose and work my way up.

I asked my endo to put in a prior authorization several times last fall, but it never happened. I stayed at 20 mcg because I didn't know if insurance would pay for Tymlos. Now with the good DEXA scores it probably won't. My endo thinks that my improvement is from Tymlos. I was going to increase it, but he said not to. My blood pressure is low, running 90/56, which is a concern. You are right I don't know what helped my DEXA score and I don't know if my bones are much better as far as not breaking.
