What Do Bearded Dragons Eat? Breaking Down the Diet
Bearded dragons‘ dietary needs change with age:
- Hatchlings and juveniles (under 12-18 months): Mostly insects (70-80%) for rapid growth, with daily greens.
- Adults: Shift to mostly plant matter (70-80% vegetables/greens) and fewer insects (20-30%) to prevent obesity.
A typical daily salad for adults should include:
- Staple leafy greens (50%+ of the salad): Collard greens, mustard greens, turnip greens, dandelion greens, endive, and chicory.
- Other vegetables (chop or grate finely): Squash (butternut, zucchini, acorn), bell peppers, carrots, broccoli, and bok choy.
- Fruits (treat only, max 5-10%): Blueberries, strawberries, apple (no seeds), banana, or papaya — offer sparingly as they are high in sugar.

Safe insects (always gut-load them 24-48 hours before feeding with nutritious veggies):
- Crickets, dubia roaches, black soldier fly larvae (excellent calcium source), silkworms, and occasional superworms or mealworms (limit these as they’re fatty).
Essential Supplementation for a Healthy Bearded Dragon Diet
Dust insects and salads lightly with:
- Calcium powder (phosphorus-free, without D3 or with D3 depending on your UVB lighting) — daily for growing dragons, every other day for adults.
- Multivitamin powder — 1-2 times per week.
Proper UVB lighting is crucial because it helps your dragon absorb calcium. Without it, even the best diet can lead to health problems.
Feeding Schedule and Tips
- Feed adults once daily or every other day.
- Offer insects in the morning; remove uneaten ones after 15-30 minutes.
- Provide fresh salad daily in a shallow dish.
- Always chop greens and veggies into small, bite-sized pieces to prevent choking or impaction.
- Variety is key — rotate foods to ensure balanced nutrition.

Foods to Avoid
- High-oxalate greens like spinach or Swiss chard in large amounts (they bind calcium).
- Avocado, rhubarb, onion, garlic, or fireflies (toxic).
- Wild-caught insects (risk of parasites/pesticides).
Final Thoughts on Bearded Dragon Nutrition
A proper bearded dragon diet keeps your pet active, prevents common health issues, and helps them live 10+ years. Always consult a reptile vet for personalized advice, especially if your dragon shows signs of poor appetite or lethargy.
If you’re setting up your first bearded dragon, focus on high-quality UVB, proper temperatures, and fresh food daily.
