Because of the fact that feeding bearded dragons large quantities of spinach may actually block calcium from getting into their bodies, it will be a good idea to limit how much you give them. As long as you only give your bearded dragon a small amount of spinach you should be fine.

In spinach there are a lot of important things for the body, such as Vitamin A, oxalates, vitamin D, and antioxidants which can fight off toxins in the body as well as bacteria which can make one sick. In order to keep your bearded dragon as healthy as possible you should avoid feeding them too much spinach.
