5 reasons why bearded dragons cannot eat green onions

If you need more convincing about why not to feed your bearded dragon onions, then here is a list of reasons why bearded dragons cannot eat green onions or any onions for that matter.

High Acidity:

Also, it will create irritation down the throat too. This will result in the beardies not eating anymore.

Low Nutritional Value:

The vegetable’s rather toxic to the creature but has no potentially good nutrients that would make it worth it. Due to how low nutritional values are present in the onion.


Due to how high the acidity of the vegetable is, it will cause serious unwanted health problems. Serious problems like heartburn. This will make the beardie agitated.

Disrupting Digestion:

After ingesting the onions, the contents of the onions will mess up the digestive enzymes beyond recognition and make them inactive.

Eventually, the beardie will get weaker due to poor digestion and absorption of nutrients.

Disproportionate CaP:

The onions have an unbalanced amount of calcium and phosphorus.

We know that the proper ratio between the calcium and phosphorus for the beardies needs to be 2:1 respectively. However, that’s not the case in onions.

This is because there’s too much phosphorus in the onions, and that interferes with the calcium intake of the body for the beardies.
