In brief: 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.

In brief: 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.
