A year ago my Vit D level was around 25. My Oncologist Rx'd 60,000 iu weekly in order to get it back up to a reasonable level. I purchased a bottle of Vit D3 (2,000 iu ea dose) and started taking 4 per day. Six months later it was checked again and it had only risen to 40, which is in the low range of normal. I backed off to 3 per day and 6 months later the level was 84. My doctor advised to cut back to 1 per day and we would check it again in December.
There has been a lot written about the possibility that D3 may help discourage PC cells from growing, but that is not the reason I take it. During the 27 months that I was on Lupron, I was not aware of the possibility of bone loss, being a side effect. As a result, I now have severe osteoporosis and must take a biophosphonate (Fosamax) in order to stop the loss and attempt to rebuild new bone. Therefore, I take Vit D3 along with 2,000 mg of Calcium Citrate per day.
Since I am blessed with PC, COPD, Osteoperosis, skin cancer, and who knows what else, am I concerned about OD'ing on D3?. Give me a break.........
