Dr. XXXXXXX At this point, I have not had a level done in over a year, but I was told by my doctor to continue the $50K/wk because she was concerned about me low level and getting osteoporosis. I have osteopenia in one hip and some loss of bone density in the lower back. Prior to taking the Replesta, I had taken a prescription Vit D for my low D levels. I don't think my level has ever been as high as 30.
