Hmmm, maybe you need Calcium by itself. Here is why I asked:
Vitamin D toxicity
If you have calcium supplements and you also take vitamin D medicines separately along with it, it could lead to vitamin D toxicity. The normal vitamin D levels in your body is 30-70 ng/ml and if it goes above 100 ng/ml, it is known as vitamin D toxicity which is caused by the build-up of calcium in your blood. The symptoms of vitamin D toxicity are nausea, weakness, frequent urination and loss of appetite. In the long run, it could lead to kidney problems.
