Yes.

Superworms contain unusually high amounts of phosphorus, which can prevent your pet from absorbing calcium properly. For perspective, the ideal dietary Ca:P ratio for most captive reptiles is 2:1, and superworms have an average ratio of 1:13.5.

You can resolve this issue by dusting superworms with high-quality, superfine calcium powder before feeding. Stick the worms in a paper or plastic bag with calcium powder inside and gently shake until they are evenly coated.
