Most pet reptiles require some form of dietary supplement to keep them healthy; this is particularly true of lizards and tortoises. The most common supplement is a calcium balancer; this may be in the form of pure calcium or as part of a combined calcium and multivitamin powder. We have a selection of different supplements for use with a wide range of species and under different conditions. The best supplement to use is often determined by two main factors, the species of animal you are keeping and the type of UVB lighting you are providing. If you are still unsure which supplement you need just drop us a message through the contact page with this information and we will be able to make a recommendation for you.
