My Doctor Wants Me To Take A Calcium Supplement Of

My doctor wants me to take a calcium supplement of 1200 mg. I had a bone density test and was slightly on the low level but it was not serious. I get 500 mg from cheese per day and am taking a supplement every other day that has 300 mg. I eat a well balanced diet and get additional calcium from other foods but have never measured this. My doctor did not want to listen to my concerns. What are your suggestions for a solution? Thank you.
