1500 mg: 1500 mg is the recommended calcium intake for women with low estrogen levels, including women who have gone through menopause, had a hysterectomy with ovaries removed, or are taking meds like Arimidex that lower estrogen levels. Because vitamin d is necessary to absorb calcium, taking a 1000-2000 iu of vitamin d3 is a good idea as well.

1000 mg: Arimidex markedly lowers estrogen levels and thereby increases bone loss. About 1000 mg calcium daily with adequate vitamin d gives partial protection but osteoporosis medication may be necessary if the bone density is low.

1200 mg a day.: You're 39 and on arimidex. I suppose you already had a bilateral oophorectomy? Or are also taking Lupron or zoladex?1200 mg of calcium and 800 international units (iu) of vitamin d daily are suggested. To make it easy, patients can take something like caltrate that has 600 mg calcium per pill and 400 to 500 iu vitamin d per pill. Patients usually take one pill twice a day. All the best, hk.
