Can Bearded Dragons Eat Kale: The Benefits and Risks of Feeding Kale to Bearded Dragons

Yes, bearded dragons can eat kale in moderation as part of a balanced diet. However, kale should not be the primary source of vegetables in a bearded dragon’s diet, as it is high in calcium oxalates that can bind to calcium, making it unavailable to the dragon and potentially leading to metabolic bone disease.

It is important to provide vegetables and fruits to your bearded dragon, including leafy greens such as collard greens, mustard greens, turnip greens, squash, carrots, bell peppers, and berries. Variety is key to providing your bearded dragon with a balanced and nutritious diet.

The Benefits of Feeding Kale to Bearded Dragons

Vitamins and Minerals

Kale is a leafy green vegetable that is a source of vitamin A, which is important for the health of the eyes, skin, and immune system. Vitamin A helps to maintain healthy mucous membranes, which can protect against respiratory infections and also supports the development of healthy bones.

This vegetable is also high in vitamin C, an antioxidant that can help protect against cellular damage caused by free radicals. Vitamin C is valuable for immune system function and can help promote iron absorption from plant-based foods. Kale also has potassium, which is important for maintaining healthy fluid balance and blood pressure levels and plays a role in muscle function and nerve transmission.

Further, kale is a rich source of vitamin K, which plays a role in blood clotting and bone health. Vitamin K is essential for the synthesis of osteocalcin, a protein that is important for bone mineralization. It also contains a good amount of calcium, which is important for developing and maintaining healthy bones and teeth. Calcium also plays a role in muscle contraction and nerve function.


Kale contains both soluble and insoluble fiber. Soluble fiber dissolves in water and creates a gel-like substance in the digestive tract, which can help slow down nutrient absorption and regulate blood sugar levels. Soluble fiber can also lower cholesterol levels and promote the growth of beneficial gut bacteria.

Insoluble fiber does not dissolve in water and adds bulk to the stool, which can promote regular bowel movements and prevent constipation. Insoluble fiber can also help promote the feeling of fullness, aiding in weight management. When bearded dragons eat kale, the fiber in the vegetable passes through the digestive tract largely undigested, adding bulk to the stool and promoting regular bowel movements. 

This can help prevent constipation, a common problem in bearded dragons. Additionally, the soluble fiber in kale can help regulate blood sugar levels and promote the growth of beneficial gut bacteria, contributing to overall digestive health. 


Kale is a nutritious and flavorful addition to a bearded dragon’s diet, which can help to add variety to their meals. It has a slightly bitter and earthy taste, which can add variety to a bearded dragon’s diet and provide them with a new flavor to enjoy. Bearded dragons can become bored with a monotonous diet, so adding new flavors to their meals can help to keep them interested in their food.

The said vegetable also has a unique texture that is different from many other vegetables that bearded dragons eat, such as carrots or squash. The leaves are slightly tough and chewy, which can provide a different texture experience for the bearded dragon.

As mentioned, kale is a rich source of many vitamins and minerals that bearded dragons need for optimal health, including vitamins A, C, calcium, and potassium. Including kale in their diet can provide different nutrients that may not be present in other vegetables they are eating.

Bearded dragons can become bored with the same feeding routine, so feeding kale differently can provide a new experience. For example, kale can be fed raw or cooked, torn into small pieces or chopped, or made into a puree or smoothie.

The Risks of Feeding Kale to Bearded Dragons

High Calcium Oxalate

While kale can provide many nutritional benefits to bearded dragons, it is important to be aware of its high levels of calcium oxalate. Calcium oxalate is a compound that can bind with calcium, making it unavailable for absorption by the body. Here’s how the high calcium oxalate content in kale can harm bearded dragons:

Bearded dragons are prone to developing kidney disease, and the high levels of calcium oxalate in kale can exacerbate this condition. When bearded dragons consume high levels of calcium oxalate, the compound can accumulate in their kidneys and cause damage to the kidney tissue.

As calcium oxalate binds with calcium, it can make calcium unavailable for absorption by the body. This can cause calcium deficiency, which can cause a range of health problems in bearded dragons, including metabolic bone disease, seizures, and even death.

The high levels of calcium oxalate in kale can also cause digestive issues in bearded dragons, including bloating, gas, and diarrhea. In extreme cases, consuming too much calcium oxalate can lead to gastrointestinal obstruction.

Other calcium-rich vegetables, such as collard greens, mustard greens, and turnip greens, may be better options for providing calcium to bearded dragons without the risk of calcium oxalate accumulation. Additionally, bearded dragons should always have access to clean water, as dehydration can exacerbate kidney disease and other health issues.


Goitrogens are a group of compounds found in certain foods, including kale, that can interfere with the function of the thyroid gland. The thyroid gland regulates bearded dragons’ metabolism, growth, and development. Goitrogens in kale can interfere with the function of the thyroid gland by inhibiting the uptake of iodine, which is necessary for the production of thyroid hormones.

Bearded dragons rely on thyroid hormones for proper growth and development. Exposure to high levels of goitrogens in kale can lead to stunted growth, delayed development, and other developmental issues in bearded dragons. Thyroid hormones also play a role in the reproduction of bearded dragons. Exposure to goitrogens in kale can lead to reduced fertility, decreased hatch rates, and other reproductive issues.

It’s important to note that not all bearded dragons are affected by goitrogens similarly. For example, some bearded dragons may be more sensitive to these compounds than others, and the effects can vary depending on the individual animal’s health status and overall diet.

Digestive Issues

Kale is high in fiber, which can be difficult for bearded dragons to digest in large amounts. Unfortunately, too much fiber can lead to bloating, gas, and diarrhea, which can be uncomfortable and even painful for bearded dragons.

As previously mentioned, kale also contains high levels of calcium oxalate, which can lead to gastrointestinal issues in bearded dragons. In addition, the compound can cause irritation and inflammation in the digestive tract, leading to digestive upset and even obstruction.

In addition, If kale is not properly washed before feeding, it may contain pesticide residues that can also cause digestive issues in bearded dragons. In addition, pesticides can irritate the digestive tract and cause diarrhea, vomiting, and other gastrointestinal symptoms. 

To avoid digestive issues caused by kale, bearded dragons should only be fed kale in moderation as part of a balanced diet. It’s also important to wash all produce thoroughly before feeding to remove any pesticide residues that may be present.
