Having used the product for over a decade Nutrobal is the preferred brand of calcium and multivitamin supplement of Professional Zoologist Will Thomas. Since the availability of high output reptile UV sources like the Arcadia T5 range care should be taken when using Calcium supplements with added Vitamin D3 in conjunction with high output UV sources. Here’s what the manufacturer says about their product:

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.

The Calcium:Phosphorus ratio is very important in ensuring healthy bone growth, and reproductive function and this potent supplement with a Ca:P ratio of 46:1 is extremely valuable in correcting deficient diets.

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.
