Brief Answer:
Yes, supplementation can cause high calcium levels.

Detailed Answer:
Hi welcome to HCM,
Yes, supplementation can cause high calcium levels. In fact it is advocated that people on Calcium, D and B12 supplements, monitor their levels frequently. Excess is also bad.
High calcium levels can lead to feeling sick, nauseous, reduced appetite, muddled, tired and irregular heart beat.
Additionally, it can get deposited in various parts of the body and lead especially to hardening of arteries and kidney stones.
Please get your levels tested to see whether they are high. Meanwhile--
You can drink a lot of water to try and flush out excessive calcium.
Other options your doctor may try if needed are--Biphosphonates and Calcitonin.
You can revert back. Regards
