Hi Kath, I have been taking a compounding prescription for the last couple of years - 20,000 ic per week in one capsule.
Despite living in sunny Queensland I work indoors all week and protect my fair skin outside. I have some loss of bone density in my hip so this was recommended. My GP believed it would also help counteract the joint pain side effect of Arimidex. Not sure if this is the case but 2 months in and I don't have any pain. all the best, Jane :)
