I'm not saying to supplement the CGD with the human multivitamin. That would throw off the balance in the food. I'm saying if you are going to dust the crickets or other prey item with it or using the baby food, using the human multivitamin and calcium supplement is better than the one made for reptiles. It's basically the same. The reptiles stuff is based on the human stuff. There is no study done on reptiles nutrition and all the stuff we assume is based on the human stuff. And, yes, the multivitamin alone doesn't contain enough calcium. You still need to supplement calcium is you are feeding you CG crickets and baby food.
