Hope vitamin D helps....... I have had significant problems with OI for a couple of years now.....in September my Vit D level was checked for the first time - it was 7. I understand that 32-100 is the normal range.......I was started on Vit D 5000 iu every other day (doc said to start slow).....8 weeks later it is up to 23....I don't feel any better yet, but I can still hope I guess.....I understand 60 to 100 is better for people like us? Anyone been told what a good level would be? I mean 32-100 is a rather large range...... I tried a beta-blocker to help OI a couple of years ago, but could not tolerate it at all. Wasn't offered Florinef - can't remember why, but it was not thought to be an option for me.
