What the interaction means

The NIH ODS calcium fact sheet names dolutegravir, levothyroxine, lithium, and quinolone antibiotics as its documented drug interactions -- CoQ10 is not among them. NCCIH's CoQ10 page names exactly three interaction concerns -- warfarin, insulin, and some cancer treatments -- and calcium is not among them either.

No documented interaction between Calcium and CoQ10 (Coenzyme Q10) was identified in the authoritative sources reviewed. This is not a guarantee that no interaction exists for every dose, formulation, or individual -- it means the sources checked did not document one.

Practical context

Calcium's NIH ODS fact sheet and NCCIH's CoQ10 page were checked directly, full text, in both directions. Neither source names the other.
