Brief Answer:
yes...

Detailed Answer:
Hello,

yes, it is possible. The body usually manages calcium excess but consuming too much calcium may cause elevation of its blood levels. Other causes will have to be excluded though.

Your calcium levels are not that high. Most labs consider 10.5 to be marginally normal. The albumin level has to be taken into account as well. If your albumin levels are low then your calcium is definitely high. Otherwise it may be normal. Sometimes other factors may come into play like technical matters during blood drawing.

So in conclusion, although your calcium is not really high, checking the albumin levels first and repeating the test is recommended. If it's high then measuring the PTH (parathormone) levels is the next step. Primary hyperparathyroidism is one of the most common causes. When all significant causes have been excluded then the calcium supplements can be blamed.

I hope it helps!
Kind Regards!
