I use the Calcium Plus product created by Allan Repashy, and so far, it's working out really well for me. I am raising a male leopard gecko with this product and he is growing extremely well and has very nice colors...vibrant and beautiful. My rescued citrus bearded is also doing very well on it. She's very active and alert and has a great appetite. If you do use this product, you do not need to supplement with anything else. It has all the calcium and other minerals and vitamins that a bearded needs. I dust the prey insects every time I feed them roaches or other insects. This product is designed to help round out the nutritional value of the insects, in the case that it's deficient in some vitamins or minerals. For the veggies I use the Veggie Dust, also created by Allen Repashy. The Veggie Dust and Calcium Plus are two different products. You cannot use them interchangeably! A lot of people made that mistake. Hope this help! :wink:
