Like "I'm taking both the calcium and vitamin D. The calcium was started about 5 years ago, because I'm, Lactose intolerent. I don't or can't have dairy products. I had fractured my femur that year that I was told to take calcium supplements. Vitamin D was just prescribed for me last year after a blood test showed I was not getting enough Vitamin D. The Nepherologist scripted a dosage of 50,000 units of vitamin D once a month. Neither Doctor has said anything so far about the use of both of these drugs."
