Can Bearded dragons eat grapes is your question? Then here is the answer to it. Bearded dragons can eat grapes, but only sometimes. If your bearded dragon has eaten a single grape, then it’s not toxic or will not cause any metabolic change in the body. Grapes are of great nutritive value and consist of water and carbohydrates. Grapes consumption in less quantity, i.e., one or two, will not cause any change in the body of the bearded dragon, but it can cause toxicity if given in more quantity. The oxalic acid compounds in the grapes combine with the calcium eaten by the bearded dragon, inhibiting its absorption. So let’s take a brief description related to the consumption of grapes by bearded dragons.

What Are the Components Present in Grapes? Can Bearded Dragon Eat Grapes?

Components Present in Grapes

Grapes consist of many components that are essential as well as harmful to the bearded dragon. So here is the list of the components with their importance in the diet of the bearded dragon. can bearded dragons eat grapes?


Water is the biggest component in the grapes. There is around 80% of water in the grapes that you consume. Water can cause diarrhoea and some dehydration problems in your bearded dragon. But this can happen only if your bearded dragon consumes the grapes frequently or consumes more than one, so if you think that bearded dragons can eat grapes, then it’s yes.


The percentage of carbohydrates is around 18.1 g, and it is the second most common component in grapes. Consumption of a lot more grapes can cause hyperglycemia in your bearded dragons and can lead to dehydration. However, dehydration does not directly correlate with hyperglycemia.

Oxalic acid:

It is one of the toxic components that are present in grapes. Oxalic acid is digested in human beings, but the metabolism is different in bearded dragons. The bearded dragons consume the grapes, and the oxalic acid combines with the calcium leading to bony disorders. But if the grapes are given in less quantity, then they are no more harmful to your bearded dragons.

Calcium to the Phosphorous Ratio:

The grapes have a calcium-to-phosphorous ratio of around 1:2. The ideal requirement for the calcium-to-phosphorous ratio is 2:1, and it is opposite to what is expected or required. So here comes the problem. The phosphorous helps the absorption of calcium by combining it with calcium. So 2 molecules of phosphorous are required for the absorption of calcium. The deficiency of phosphorous leads to bony disorder, i.e., metabolic bone disease.

What Are the Serious Problems with Feeding Bearded Dragons with Grapes?

There can be many serious problems if you are feeding your bearded dragon with grapes in large quantities. The components such as water, carbohydrates, and oxalic acid increase the risk of developing these disorders in the bearded dragon and can lead to deformity in your beardie. So here are the disorders provided below with their details and how the components contribute to having such conditions. So let us start;

MBD(Metabolic Bone Disease): 

This is the most common disorder that your bearded dragon can suffer from frequent consumption of grapes in large quantities. MBD is a bone disorder in which the bones become fragile. The main components that keep the bones strong are calcium and phosphorous. However, phosphorous helps the active absorption of calcium and is not directly involved in bone formation. Calcium is responsible for bone formation. The main problem with your bearded dragon starts here.

Oxalic acid is one of the most important components present in grapes. The oxalic acid, in combination with the calcium, decreases the absorption of the calcium from the gut of the bearded dragon. And without calcium absorption, the blood calcium becomes less. This is related to the decrease in osteoporosis and the bones becoming fragile. So as a consequence, the bones of your beard will become less strong and will sometimes get broken easily. This will result from the walking deformity of your bearded dragon. This way, grapes can become toxic due to the oxalic acid component present in them.


Diarrhoea is not a serious issue that is caused by the consumption of grapes by a beaded dragon. As grapes are the most common source of water as well as carbohydrates, there are chances that there can be diarrhoea due to the absorption of more water and the removal of the same. Consumption of a lot of grapes can lead to diarrhoea.

Ideal Diet for My Bearded Dragon

Bearded dragons are omnivorous, i.e., they can eat both vegetarian as well as non-vegetarian diets.

You can give the mixed fruit and vegetable diet to your bearded dragon. The leafy vegetables or the leaves of certain plants are the favourite food of beardies.

Animal-based diet: Initially, in the first few days of the bearded dragon’s life, you must be quite sophisticated about providing the animal-based diet. Once your bearded dragon is well grown, you can provide 60 to 70 % of the diet included as the animal-based diet.
