My oncologist prescribed a baseline DEXA prior to my starting on Anastrozole ( an AI like Letrozole) which also may causes bone loss. I consulted an endocrinologist to plan any mitigation strategy I may need. My bones are in relatively good shape. However, My endocrinologist recommends NO calcium supplementation ONLY calcium from food and Vitamin D ( gel tablets are best as D is fat soluble). I also take K2 which she doesn’t start people on but doesn’t suggest stopping if you’ve started as research suggests it “may” be helpful in directing calcium to bones and away from soft tissue as in arterial plaque. CAUTION: check with cardio about K2 as there are two kinds of K and one has cardio implications.

So food based calcium is what I do! Organic Grass fed non fat or lo fat dairy, Parmesan cheese is hi in calcium, green leafy veggies but some like spinach are hi in Oxalates ( binds calcium) but bok choy, kale, and organic calcium fortified plant milks and Uncle Matt’s Organic OJ ( with calcium and Vitamin D has blue label). The internet has many websites listing foods hi in calcium.
