The Complete Bearded Dragon Diet Guide (2026)

Bearded dragons are omnivores with dietary needs that change dramatically as they grow. Getting the diet right is the single most important thing you can do for your beardie's health, coloration, energy level, and lifespan. This guide covers everything — insects, vegetables, fruits, supplements, feeding schedules, and common mistakes — based on the latest veterinary recommendations and experienced keeper knowledge.

Diet Ratio by Age

Best Insects for Bearded Dragons

#1: Discoid Roaches — Daily Staple

20% protein, 7% fat, 0.77:1 Ca:P. The ideal daily protein feeder. Silent, odorless, cannot climb or bite. Gut-loads exceptionally well. Legal in all 50 states including Florida (unlike dubia roaches). Available in small, medium, and large.

#2: Silkworms — Premium Low-Fat Supplement

1% fat (lowest of any feeder), 83% moisture, zero chitin, serrapeptase enzyme. The leanest feeder for preventing adult beardie obesity. Also the best feeder for picky beardies that refuse other food. Feed 2-3x per week.

#3: BSFL / Black Soldier Fly Larvae — Calcium Powerhouse

9,340 mg/kg calcium, 6.92:1 Ca:P ratio. The ONLY feeder that does not need calcium dusting. Feed 1-3x per week for natural calcium supplementation that prevents MBD.

#4: Hornworms — Hydration Treat

85% moisture, 3:1 Ca:P. The feeder that makes beardies go wild. Bright color triggers explosive feeding response. Excellent for hydration and appetite stimulation. Feed 1-3x per week.

Occasional Treats

Superworms: 1x per week max for adults only. 18% fat. Mealworms: 1-2x per week for adults only. Not for juveniles (impaction risk). Waxworms: Very rarely — once every 2 weeks max. 25% fat, highly addictive.

Best Vegetables for Bearded Dragons

Daily Staple Greens (offer every day)

• Collard greens — high calcium, the #1 beardie green
• Mustard greens — high calcium, readily eaten
• Turnip greens — strong Ca:P ratio
• Dandelion greens — outstanding nutrition (pesticide-free only)
• Endive and escarole — good variety options

Other Good Vegetables

• Butternut squash, acorn squash (high vitamin A)
• Bell peppers (red, yellow, orange — vitamin C)
• Green beans, snap peas
• Carrots (grated — vitamin A)
• Zucchini, yellow squash

Vegetables to Avoid or Limit

• Spinach: High oxalates bind calcium — use sparingly
• Iceberg lettuce: Almost no nutritional value
• Avocado: Toxic — never feed
• Rhubarb: Toxic — never feed

Fruits (Treats Only — 10% of Diet Max)

• Blueberries, strawberries, raspberries
• Mango, papaya (vitamin A)
• Apple slices (remove seeds)
• Grapes (cut in half)
• Banana (sparingly — high sugar)

Fruits are high in sugar and should be offered as treats, not daily staples. A few pieces mixed into the salad 2-3 times per week is plenty.

Supplementation

The Ideal Weekly Schedule (Adult Beardie)

• Monday: 10-15 discoid roaches (Ca+D3 dusted) + collard green salad
• Tuesday: Salad only — collard greens, squash, bell pepper, few blueberries
• Wednesday: 2-3 hornworms + 5 roaches + salad
• Thursday: Salad only
• Friday: 5-8 silkworms (Ca dusted) + salad
• Saturday: 10-15 roaches + 10-15 BSFL (no dusting) + salad
• Sunday: Salad only or light insect feeding

Common Diet Mistakes

• Mealworm-only diet: 13% fat, poor Ca:P (0.04:1), impaction risk for juveniles. Use roaches instead.
• Cricket-only diet: Smell, noise, bites, escapes, poor Ca:P. Switch to discoid roaches.
• Overfeeding adults: Insects every other day, not daily. Obesity is the #1 health issue in adult beardies.
• Skipping vegetables: Adults need 60% of diet from greens. Offer daily even if initially refused.
• Waxworm addiction: Beardies become addicted and refuse other food. Avoid or use very rarely.
• No UVB: Without UVB, calcium cannot be absorbed regardless of diet. Non-negotiable.
