There is a beardy, whole food 100% nutritionally complete powdered slurry sold on Etsy. I have been feeding this to my beardy and she loves it! I still feed her insects once in a while with. The powdered slurry contains all the vitamins (including calcium and d3) but is easier for beardies to digest than synthetic supplements, and safer too. My beardy is 3 years old and very healthy. Maybe this would be good for your beardy
