I'm new but I have read several post where people question the importance of mammal or human vitamins ove the reptile vitamins suggested by the different
diets. Before I got my suggie I kept reptiles and am trained as a herpetologist btu had to give up several pets because of new laws where I live. Mammal vitamins are typically derived from fruits and vegetables or synthetically made in labs, they work as a daily supplement but are weak compared to ones for reptile vitamins. Things like reptical are actually made from grinding bone from small animals, and the otehr reptile vitamins are usually made from by pulverizing and boiling meat. When you go to a pet store and look on the ingredients for the different types of vitamins and calcium you should see the percent concentration which are very for apart between things made for everyday mammals, and things designed for high end reptiles and other calcium dependent animals.
