@olderdiva12345: Personally, I think you are taking way too much calcium, which is 5200 mg daily based on one of your earlier posts.

The recommended daily amount of calcium is 1200 mg , and it's recommended a person should get as much of that through their diet (vs. supplements). It's not recommended to take more than 1200 mg daily, even if one has osteoporosis -- see the "Guidelines if you are taking calcium supplements for osteoporosis" link at https://www.hsph.harvard.edu/nutritionsource/calcium/,

I strongly urge you to review your supplements with your doctor or registered dietician. Taking too much of a vitamin and/or mineral may be dangerous, can cause health problems, and/or be a waste of money, In other words, more is not necessarily better.
