Can Bearded Dragons Eat Banana?

Bearded dragons should not eat bananas. While they could eat banana
occasionally, banana can also make them sick. Bananas are high in phosphorus, which is known to bind with calcium in the digestive system. They are also very high in vitamin K, which can be toxic if dragons eat too much of it.

If your beardie eats a lot of banana, it can become calcium deficient. This will weaken their bones and cause Metabolic Bone Disease.

So, while eating banana very occasionally will not kill your dragon, there are many other safer options out there to feed it as an alternative.
