Bearded Dragon Care Guide
Bearded Dragon Food List: What Can Bearded Dragons Eat? (Complete 2026 Guide)
Updated July 31, 2026 · Reviewed against captive reptile husbandry standards
The #1 rule: diet changes with age
The single most common feeding mistake is treating an adult bearded dragon like a baby. Newly hatched dragons need massive protein to grow, but adults are built to eat mostly plants.
| Age | Insects | Greens/Veg | Frequency |
|---|---|---|---|
| Baby (0-3 mo) | 80% | 20% | 2-3x daily |
| Juvenile (3-12 mo) | 70% | 30% | 1-2x daily |
| Subadult (12-18 mo) | 50% | 50% | Daily |
| Adult (18+ mo) | 20% | 80% | Every 2-3 days |
Overfeeding insects to adults causes obesity, fatty liver disease, and a shortened lifespan. If your adult dragon gets mostly bugs, slowly swap the ratio toward greens.
🥬 Best staple greens (feed daily)
These leafy greens are high in calcium and low in harmful oxalates — the foundation of an adult's diet. Rotate several types for balanced nutrition:
- ✅ Collard greens — excellent calcium-to-phosphorus ratio, the #1 staple
- ✅ Mustard greens — high calcium, well accepted
- ✅ Dandelion greens — nutritious, a natural favorite (use pesticide-free)
- ✅ Turnip greens — great calcium source
- ✅ Endive / escarole — good hydration and fiber
Chop greens to roughly the size of the space between your dragon's eyes (especially for babies). Lightly dust with calcium before serving.
🥕 Safe vegetables to mix in
✅ Feed regularly
- • Butternut squash (grated)
- • Acorn squash
- • Bell peppers (all colors)
- • Green beans
- • Cactus pads (nopales)
- • Parsnip (grated)
- • Snap peas
⚠️ Occasionally (high oxalates)
- • Carrots (grated, 1-2x/week)
- • Sweet potato (cooked, rare)
- • Kale (in rotation only)
- • Broccoli (small amounts)
These bind calcium if fed too often.
🍓 Fruits (treats only — 5-10% of diet)
Fruit is candy for bearded dragons. Offer small pieces once or twice a week at most:
Blueberries, raspberries, strawberries, papaya, mango, apple (seedless), peeled pear, and a tiny bit of banana. Always remove seeds/pits and chop small.
🦗 Best feeder insects
Insect quality matters as much as the greens. Always gut-load feeders for 24 hours before offering (feed them nutritious greens and a gut-load formula so the nutrition passes to your dragon). Never feed an insect wider than the space between your dragon's eyes.
| Insect | Use as | Notes |
|---|---|---|
| Dubia roaches | Staple | Best nutrition, low chitin, easy to keep |
| Black soldier fly larvae | Staple | Naturally high in calcium |
| Crickets | Staple | Affordable, gut-load well, but smelly/noisy |
| Hornworms | Treat/hydration | High moisture, great for underweight dragons |
| Mealworms | Occasional | Hard chitin — impaction risk for babies |
| Superworms | Adult treat | Too large/hard for juveniles |
| Waxworms | Rare treat | Very high fat — like junk food |
🚫 Never feed these (toxic or dangerous)
- ☠️ Fireflies / lightning bugs — EXTREMELY toxic; even one can kill a dragon within hours
- ☠️ Avocado — toxic to reptiles
- ☠️ Rhubarb leaves — high oxalic acid, poisonous
- ☠️ Any glowing insect — luminescence signals toxicity
- 🚫 Onion, garlic, chives — damage red blood cells
- 🚫 Citrus fruits — too acidic, causes digestive upset
- 🚫 Iceberg lettuce — almost no nutrition, causes diarrhea
- 🚫 Spinach — calcium-binding oxalates (avoid entirely)
- 🚫 Wild-caught insects — parasites and pesticides
- 🚫 Any human processed food, dairy, meat
🦴 Calcium & supplements
Even a perfect diet is not enough without supplementation. Without calcium and UVB, bearded dragons develop metabolic bone disease (MBD) — a painful, often permanent condition.
- • Most feedings: dust insects with calcium with D3
- • 2-3x weekly: lightly dust salad with calcium without D3
- • 1-2x weekly: dust with a reptile multivitamin (replaces calcium that meal)
- • Provide strong UVB (T5 HO 10-12%) and replace bulbs every 6-12 months
🗓️ Sample daily feeding routine
- Morning: offer a fresh chopped salad (collard/mustard/dandelion greens + grated squash). Mist lightly.
- Midday: for young dragons, offer a bowl of properly-sized, calcium-dusted insects — as many as they'll eat in 10-15 minutes.
- After 15 minutes: remove all uneaten insects (they bite and stress dragons).
- After 4 hours: remove uneaten salad so it doesn't spoil.
- Adults: skip insects 2-3 days per week; salad every day.
