Are Mealworms Good For Bearded Dragons


Bearded dragons are popular pets known for their unique appearance and docile nature. These reptiles require a balanced diet to thrive, consisting of various insects, fruits, and vegetables. One insect that is commonly debated as a food source for bearded dragons is mealworms. In this article, we will explore the benefits and drawbacks of feeding mealworms to bearded dragons. By examining their nutritional value, potential health risks, and appropriate feeding guidelines, we aim to provide a comprehensive answer to the question: Are mealworms good for bearded dragons?

The Nutritional Value of Mealworms

Protein Richness

Mealworms are incredibly rich in protein, making them an attractive food source for bearded dragons. Protein is crucial for the growth, development, and overall health of these reptiles. According to a study conducted by the University of Florida, mealworms have a protein content of approximately 20%-50%, which is higher than many other insects commonly fed to bearded dragons, such as crickets or dubia roaches. This high protein content ensures that bearded dragons receive the necessary amino acids for proper muscle and tissue development.

Essential Fatty Acids

Another nutritional benefit of mealworms is their abundance of essential fatty acids. These fatty acids, particularly omega-3 and omega-6, play a crucial role in maintaining healthy skin, promoting proper organ function, and supporting the immune system. Mealworms contain a favorable ratio of omega-3 to omega-6 fatty acids, which aids in maintaining a balanced diet for bearded dragons.

Vitamins and Minerals

Mealworms also provide essential vitamins and minerals that contribute to the overall well-being of bearded dragons. They are rich in vitamin B12, which is crucial for the proper functioning of the nervous system and the production of red blood cells. Additionally, mealworms contain minerals such as calcium and phosphorus, which are vital for bone health and muscular function in bearded dragons.

Potential Health Risks of Feeding Mealworms

While mealworms offer several nutritional benefits, there are potential health risks associated with feeding them to bearded dragons. It is crucial to consider these risks and take appropriate precautions when incorporating mealworms into their diet.

Chitin Content

One concern with feeding mealworms to bearded dragons is their high chitin content. Chitin is a polysaccharide that forms the exoskeleton of insects. While bearded dragons can digest chitin to some extent, excessive consumption may lead to impaction, a condition where undigested material accumulates in the digestive tract, potentially causing blockages and discomfort. Therefore, it is important to ensure a balanced diet that includes a variety of other insects and foods to minimize the risk of chitin buildup in bearded dragons.

High Fat Content

Mealworms have a higher fat content compared to other insects commonly fed to bearded dragons. While the essential fatty acids in mealworms are beneficial, excessive fat intake can lead to obesity and related health issues in bearded dragons. It is essential to feed mealworms as part of a well-rounded and diverse diet, ensuring that fat intake remains within healthy limits.

Lack of Calcium

While mealworms provide various nutrients, they are deficient in calcium. Calcium is essential for bearded dragons, as it plays a significant role in bone development and overall health. Therefore, relying solely on mealworms as a primary food source may lead to calcium deficiency in bearded dragons. It is crucial to supplement their diet with other calcium-rich foods, such as leafy greens and calcium powder, to maintain proper calcium levels.

Feeding Guidelines for Mealworms

To ensure the proper incorporation of mealworms into a bearded dragon's diet, following these feeding guidelines is essential:

1. Moderation is key: Mealworms should be offered as a treat rather than a staple food source. The excessive consumption of mealworms can lead to nutritional imbalances and health issues.
2. Variety is crucial: Bearded dragons require a diverse diet to obtain a wide range of nutrients. Feeding mealworms alongside other insects, such as crickets, dubia roaches, or black soldier fly larvae, ensures a balanced nutritional intake.
3. Gut-loading and dusting: Gut-loading involves feeding the mealworms with nutritious foods before offering them to bearded dragons. This process enhances their nutritional value. Additionally, dusting the mealworms with a calcium supplement ensures that bearded dragons receive adequate calcium alongside other essential nutrients.
4. Size matters: When feeding mealworms to bearded dragons, it is important to consider their size. Large mealworms may pose a choking hazard, especially for younger or smaller dragons. Therefore, select appropriately sized mealworms based on the size and age of the bearded dragon.


In conclusion, mealworms can be a beneficial addition to a bearded dragon's diet when fed appropriately. Their high protein content, essential fatty acids, and vitamin and mineral content offer several nutritional benefits. However, it is crucial to consider the potential health risks associated with mealworm consumption, such as chitin content and high fat levels. By adhering to proper feeding guidelines, including moderation, variety, gut-loading, and dusting, bearded dragon owners can safely incorporate mealworms into their pets' diet. Remember to prioritize a well-rounded diet consisting of other insects, fruits, vegetables, and calcium-rich sources to ensure optimal health and well-being for these beloved reptiles.
