calcium+vitamin supplement substitute?

[whopper]

lately my beardie whopper has decided he does not wish to hunt apon white crickets, and he will not even show interest in them, but if i put an un-dusted cricket in with all the white ones he'll pick out the brown one and then i get the stick eye until i put more brown ones in :| ive heard of a liquid calcium supplement, but nothing about a vitamin supplement. what is the liquid calcium like? how do you get it in your beardie ect. any help would be appreciated, whoppers only about 2 months old so i know these supplements are crucial at this age and he hasnt been ingesting them for about a week.
