The list of what bearded dragons can eat is genuinely long. But knowing the list isn’t enough on its own — the ratios, frequencies, and life-stage rules are what determine whether your dragon is thriving or slowly becoming nutrient-deficient. This guide covers every food category with a clear verdict: daily staple, occasional treat, or never. Think of it as the reference you can bookmark and return to.
Quick Answer: What Do Bearded Dragons Eat?
Bearded dragons are omnivores. Hatchlings and juveniles eat 60–80% insects and 20–40% vegetables daily. Adults (12+ months) flip this: 15–30% insects 2–3 times per week and 70–85% leafy greens daily. Safe staple insects: Dubia roaches, BSFL, gut-loaded crickets. Safe staple greens: collard, mustard, turnip, dandelion. Fruits are treats only (max 10% of vegetable portion). Dust insects with calcium powder at every feeding.
Bearded Dragon Diet Overview — Omnivore by Design
Pogona vitticeps is native to the semi-arid grasslands of central Australia — an environment with high UV radiation, seasonal temperature extremes, and varying food availability. Wild bearded dragons eat opportunistically: beetles, ants, caterpillars, small lizards and their eggs, as well as seasonal vegetation, flowers, and berries.
In captivity, we replicate this mix with feeder insects + fresh leafy greens + calcium supplementation. What changes dramatically between hatching and adulthood is the ratio.
Hatchlings and juveniles need high protein for rapid skeletal growth — insects provide this. Once growth plateaus around 18 months, that same protein load becomes a metabolic burden rather than a fuel source. An adult dragon fed daily insects is at serious risk of gout, fatty liver disease, and obesity. This isn’t a minor nuance — it’s the most commonly mismanaged aspect of bearded dragon nutrition.
According to ReptiFiles’ bearded dragon food and feeding guide, the shift from insect-dominant to vegetable-dominant diet should begin around 6–12 months and be essentially complete by 18 months.
Diet by Life Stage
Hatchling Diet (0–3 Months)
| Parameter | Value |
|---|---|
| Insect : Vegetable ratio | 60–80% insects : 20–40% veg |
| Insect feeding | 2 sessions per day |
| Insect amount | As many as eaten in 10–15 minutes per session |
| Vegetable offering | Daily (offer even if ignored — establish the habit) |
| Calcium dusting | Every insect feeding |
Best insects for hatchlings: small Dubia roaches, small crickets (gut-loaded), black soldier fly larvae (BSFL). Nothing larger than the space between the dragon’s eyes.
Juvenile Diet (3–12 Months)
| Parameter | Value |
|---|---|
| Insect : Vegetable ratio | ~60% insects : ~40% veg (transitioning toward 50:50 by 12 months) |
| Insect feeding | 1 session per day |
| Insect amount | 5–6 head-sized insects per session |
| Vegetable offering | Daily; increase portion as dragon grows |
| Calcium dusting | Every insect feeding |
Avoid mealworms and superworms at this stage — the hard exoskeleton creates impaction risk in juveniles.
Adult Diet (12+ Months)
| Parameter | Value |
|---|---|
| Insect : Vegetable ratio | 15–30% insects : 70–85% veg |
| Insect feeding | 2–3× per week (NOT daily) |
| Insect amount | 3–4 head-sized per session (8–10 medium Dubia equivalent) |
| Vegetable offering | Daily — this is the primary food source |
| Calcium dusting | Every insect feeding + on salads |
Adults that eat primarily insects are at risk of gout, fatty liver, and obesity. Per VCA Animal Hospitals’ bearded dragon feeding guide, the vegetable portion of an adult’s diet should be 80–90% leafy greens.

Safe Fruits — Treats Only
Fruits are high in sugar. They should make up no more than 10% of the vegetable portion of the diet — roughly 5–10% of total diet — and should never replace leafy greens as a primary food source.
Best fruit options:
| Fruit | Notes |
|---|---|
| Cactus fruit / prickly pear | Best fruit option: lower sugar than most; naturally high calcium |
| Strawberries | Popular; limited to 1–2 per feeding session |
| Blueberries | Small size; good antioxidants; occasional |
| Raspberries | Good; small portions |
| Watermelon (seedless) | High moisture; nice hydration treat; low nutrition |
| Melon (cantaloupe) | Moderate nutrition; good occasional treat |
| Figs | Higher calcium than most fruits; excellent option |
| Peaches (peeled) | Seasonal treat; remove pit |
| Apple (peeled, cored) | Remove skin and seeds; occasional |
| Grapes (quartered) | Occasional; sugary |
| Mango | Sugary — limit |
| Papaya | Decent; high moisture |
Avoid: All citrus (lemon, orange, lime, grapefruit) — acidic; digestive upset. Raisins — dehydrated fruit; concentrated sugar.

Gut-Loading — Why It Matters and How to Do It
Gut-loading is feeding feeder insects nutritious food 6–12 hours before offering them to your dragon. Without it, feeder insects are nutritionally hollow — they’re essentially walking protein capsules with poor calcium-to-phosphorus ratios.
A properly gut-loaded cricket or Dubia delivers significantly more vitamin and mineral content than one fed only on cardboard or bran.
What to feed feeder insects:
– Collard greens, mustard greens, dandelion greens
– Sweet potato, carrot, butternut squash
– Spirulina powder (mixed into wet food)
– Commercial gut-load (Repashy Bug Burger, Mazuri Hi-Calcium Gut Load)
What NOT to feed feeder insects: Any food that’s toxic to the dragon (avocado, garlic, citrus) — what the insect eats reaches your dragon.
Timing: Gut-load 6–12 hours before feeding to the dragon. Hungry insects eat the gut-load food more aggressively; offer food in the early morning if you plan to feed the dragon by midday.
For a complete gut-loading guide with timing, product reviews, and different insect requirements, see Bearded Dragon Gut-Loading Guide.
Calcium Supplementation — The Essential Rule
Calcium dusting is the most important single feeding habit in bearded dragon care. Calcium deficiency is the primary driver of metabolic bone disease (MBD) — the most common preventable serious condition in captive dragons.
Rules:
– Dust feeder insects with phosphorus-free calcium powder before every feeding — shake insects in a container or bag with a small amount of powder
– Use D3-containing calcium 2–3× per week for hatchlings and juveniles (less for adults with good UVB exposure)
– Use plain phosphorus-free calcium on the other feeding days
– Multivitamin: 2× per week for hatchlings/juveniles; 1× per week for adults — do not use multivitamin daily (vitamin A toxicity risk with oversupplementation)
– Dust salad greens with calcium powder for adult dragons as well as their insects
Per Falls Road Animal Hospital’s bearded dragon diet guide, consistent calcium supplementation combined with proper UVB lighting is the most effective MBD prevention strategy.

Foods to Always Avoid
The full toxic food list lives at Bearded Dragon Foods to Avoid. The critical items are:
| Food | Why |
|---|---|
| Fireflies / Lightning bugs | LETHAL — even one firefly can kill a dragon |
| Avocado | Toxic (persin) — cardiovascular and respiratory effects |
| Onion, garlic, chives | Toxic — hemolytic anemia risk |
| Rhubarb | Very high oxalic acid — toxic |
| Wild-caught insects | Pesticide contamination, unknown parasite load |
| Citrus fruits | Highly acidic; digestive upset |
| Iceberg lettuce | Nutritionally empty; diarrhea risk |
| Spinach (as staple) | Oxalates — calcium binding; fine occasionally, never a daily food |
Conclusion
Feeding a bearded dragon well comes down to three habits: daily leafy greens, calcium-dusted insects on schedule, and correctly sizing prey items. Once those are consistent, you’re covering the vast majority of nutritional needs.
The food list is large — which means variety is both achievable and encouraged. Rotating through different greens and insects each week provides a broader nutritional profile than relying on one or two staple items.
