A vitamin/mineral supplement specifically formulated as a high calcium "balancer " for insectivorous reptiles and birds, to assist in correcting the inadequate levels of calcium present in live insectivorous foods such as crickets and mealworms.

It is particularly important for those species fed primarily on insects such as mealworms or locusts, used as a dusting powder. Some species fed mainly lean meat also benefit, as will growing chelonia which need calcium for their shells and the larger lizards and crocodilia for their normal bone development. Large lizards and chelonia also benefit from ACE-High.
