I went to the doctor earlier this week. He told me that he tells all women to take calcium with vitamin D. He said to build up those bones with all the calcium you can before the body starts losing it. He also told me that there is no reason for a nonsmoker that does not take steroids to get osteoporosis. So, this week I've started taking calcium with D. I'm 37. I also found out I have high cholesterol, but that is a topic for another thread.
