Feeding a bearded dragon is one of the most rewarding parts of being a reptile owner, but it can also be one of the most confusing. These charismatic lizards are omnivores, which means they need a balanced mix of animal protein and plant matter to stay healthy. As they grow from tiny hatchlings into impressive adults, their nutritional requirements shift significantly. While a baby dragon needs plenty of protein to fuel its rapid growth, an adult dragon should primarily eat its veggies.
The Foundation: Leafy Greens and Vegetables
For an adult bearded dragon, about eighty percent of their diet should consist of fresh greens and vegetables. This provides the fiber, vitamins, and minerals they need for long-term health. However, you cannot just grab any bag of salad from the grocery store. Some greens are nutritional powerhouses, while others are essentially just water or, worse, can block calcium absorption.
Staple Greens to Feed Daily
You should aim for a variety of the following greens to ensure your dragon gets a wide range of nutrients:
– Collard Greens: These are arguably the best staple for a bearded dragon. They are packed with calcium and have a great calcium-to-phosphorus ratio.
– Mustard Greens: Another excellent choice that most dragons find quite tasty. They are rich in vitamins A, C, and K.
– Turnip Greens: These are very high in calcium and are a favorite for many reptiles.
– Dandelion Greens: If you can find them in the store or pick them from a chemical-free lawn, these are fantastic for hydration and minerals.
– Escarole and Endive: These provide good variety and are very safe for daily consumption.
Vegetables to Mix In
While leafy greens are the base, adding other vegetables provides extra texture and vitamins:
– Butternut Squash: This is a fantastic staple vegetable because it is high in fiber and vitamin A.
– Bell Peppers: Red, orange, and yellow peppers are great for vitamin C, and many dragons are attracted to their bright colors.
– Green Beans: These should be chopped small and are a good source of fiber.
– Carrots: These are fine in small amounts, but they are high in vitamin A, so do not overdo it.
Avoid iceberg lettuce, as it has almost no nutritional value. You should also limit spinach and beet greens, because they contain oxalates that bind to calcium and prevent your dragon from absorbing it.

The Protein Source: Live Insects
Insects are the highlight of any bearded dragon’s day. They provide the protein and fats necessary for muscle development and energy. The most important rule for feeding insects is to ensure they are no larger than the space between your dragon’s eyes to prevent impaction or choking.
Best Staple Insects
– Dubia Roaches: These are widely considered the gold standard. They are high in protein, low in chitin, and they do not jump or climb smooth surfaces.
– Crickets: A classic choice that encourages hunting behavior. They are readily available and nutritious, but they can be noisy.
– Black Soldier Fly Larvae: Often sold as NutriGrubs or Phoenix Worms, these are naturally very high in calcium.
Treats for Occasional Use
– Mealworms: These have a tough outer shell that can be hard for younger dragons to digest.
– Superworms: Much like mealworms, these are fatty and should be used sparingly.
– Waxworms: These are basically sticks of butter for reptiles, great for putting weight on a skinny dragon.
– Hornworms: These are excellent for hydration because they are full of moisture, but they are low in protein.
The Importance of Supplements and Gut-Loading
Even the best diet can benefit from a little help. Most captive environments cannot perfectly replicate the variety of food found in the wild. This is why calcium and multivitamin powders are essential. You should lightly dust your dragon’s insects with a calcium supplement several times a week.
Furthermore, you should always “gut-load” your insects. This means feeding the bugs high-quality vegetables and fruits for twenty-four hours before offering them to your dragon. Whatever the insect eats goes directly into your lizard, so feeding the bugs healthy scraps turns them into a much more nutritious meal.
Hydration and Feeding Tips
Bearded dragons often get most of their water from their greens, but it is still important to provide a shallow water dish. You can also mist their greens with water to help keep them hydrated. When feeding, try to offer the salad in the morning so the dragon has all day to digest under their basking light. Digestion is a heat-dependent process, so a cold dragon cannot properly process their food.
Conclusion:
By providing a diverse menu of high-calcium greens and lean, gut-loaded insects, you are giving your bearded dragon the best possible chance at a long, vibrant life.
