Risks of feeding sweet potatoes to bearded dragons 

Vitamin A toxicity

Overfeeding vitamin A-rich foods to your bearded friend is not sufficient to cause vitamin A toxicity. Your main concern should be Vitamin A supplements. 

If the Vitamin A supplications are coupled with overfeeding foods rich in Vitamin A, then the toxicity is inevitable. Some of the symptoms of this toxicity include nausea, vomiting, loss of appetite, and abdominal pain.

Unbalanced calcium to phosphorus ratio

Sweet potatoes provide 30 mg of calcium and 47 mg of phosphorus per 100g which is not a healthy balance at all. The ideal calcium to phosphorus ratio is 2:1 while 1:1 is considered safe or acceptable. 

Phosphorus binds with the calcium and hampers its absorption from the intestines. Feeding calcium-poor foods to the bearded dragon, if continued over some time,  leads to Metabolic Bone Disease

This disease is characterized by paralysis, deformity, shrunken limbs, and lethargy in bearded dragons. If left untreated, it may even cause death.

How often should bearded dragons eat sweet potatoes?

Considering the high Vitamin A content and the poor calcium to phosphorus ratio of the sweet potatoes, they can be fed once per week to your lizard. To make the salad bowls wholesome and interesting, mix the sweet potatoes with other nutritious fruits or vegetables.

How to feed sweet potatoes to your bearded dragon?

Organic sweet potatoes may be a bit expensive but they are the best choice when it comes to feeding bearded dragons. It is because inorganic sweet potatoes are loaded with insecticide or fungicide residues that are toxic for your lizard. 

Therefore, your best bet is organic sweet potatoes but thoroughly washed inorganic sweet potatoes will also do.

There is no need to cook the sweet potatoes before serving them to your lizard friend. Bearded dragons can easily gobble up raw sweet potatoes. 

To prevent the sweet potatoes from becoming a choking hazard for your lizard friend, cut the tuber into small bite-sized pieces that your bearded friend can easily devour. Alternatively, grate the sweet potatoes or cut them into thin strips.

But first, peel, and thoroughly wash the sweet potatoes. Because the peel is too rough for your bearded friend to eat while the washing reduces the pesticide load of the tuber.

Can bearded dragons eat unpeeled sweet potatoes?

Yes, bearded dragons can eat unpeeled sweet potatoes. But it is not recommended especially for young bearded dragons whose throats are too fragile to ingest the rough peel of the tuber. 

Therefore, the best and the safest option is to feed raw, peeled, and cut sweet potatoes to your bearded friend.
