From my understanding it's the calcium tablets that have a bit of a rethink. I was alarmingly low in Vitamin D when I first checked (blood tests fine,no other deficiencies), and many Australian women are - it may not only be your diet (I thought mine was pretty healthy), it may be partly to do with less time in the sun. All sorts of benefits re skins, skin cancer etc, but human beings were designed for sunlight and too little has a negative effect too. I burn easily and stay covered, so that's part of the problem. I have however shrunk my calcium tablet intake, as I think I get enough from low fat milk and yoghurt. As I am on femara and my bones are definitely showing the impact (but not osteoporotic yet) I am wary of not keeping my calcium levels sufficient for bone purposes, eating healthily is unlikely to fully offset the femara all by itself. Swings and roundabouts!
