As you can see, sweet potatoes are good source of energy. This makes potatoes a good food for those who are physically active. However, it is important to remember that beardies in captivity are usually not physically active.

Their small environment constrains them from moving freely. In the wild, they used to roam and hunt insects. These things are not available in their artificial habitat.

Consuming high calorie foods is not good if the body does not use it. Physical activities are a way to use it. I suggest that you avoid feeding your beardies too much calorie-rich foods.


Bearded dragons need protein especially the younger ones. About 80% of their diet must be protein. This is the reason why they eat more insects than greens.

Sweet potato does not have enough amount of protein for beardies. This makes potatoes not good as part of bearded dragons’ staple food.

Vitamin A

As you can see, vitamin A is super high in sweet potatoes. Bearded dragons need vitamin A but only in right amount. Having too much of this vitamin is actually harmful to bearded dragons.

Beardies can suffer from vitamin A toxicity if they consumed too much vitamin A-rich foods. This is a serious condition in bearded dragons. It commonly happens when reptiles are given vitamin A supplements while eating vitamin A-rich foods.

Supplements are helpful for bearded dragons. No matter how balanced their diet is, they still need supplements. But just be careful not to overfeed them supplements.


Sweet potatoes also contain calcium. Calcium is beneficial for beardies in developing healthy and stronger bones. The lack of calcium may cause health issues. The most common one is metabolic bone disease.

Metabolic bone disease is a health condition in bearded dragons characterized by weak and brittle bones. This could cause many behavioral issues in beardies too. Trust me, you don’t want to see your beardies suffer from this condition.


Sweet potato is also a good source of phosphorus. This mineral plays a vital role in the maintenance and repair of cells and tissues in the body. Bearded dragons surely need phosphorus.

However, the problem with sweet potato is that it has disproportionate calcium-to-phosphorus ratio. As you can see, the phosphorus level is higher than calcium.

Remember that one of the considerations when choosing foods for bearded dragons is the calcium and phosphorus content.

The ideal ratio is 2:1 (calcium to phosphorus). Unfortunately, sweet potato has higher level of phosphorus than calcium making it inappropriate food for beardies.

If you want to feed your beardies sweet potatoes, make sure that it is not more than a treat. Too much of this food is definitely not a good idea for bearded dragons.
