The best food for a bearded dragon is a rotating mix of protein-rich feeder insects, leafy greens, and a calcium supplement, adjusted for your dragon's age. Young beardies eat mostly insects like crickets and dubia roaches, while adults lean more on plants. The ten picks below cover every part of that plan, from staple feeders and high-value treats to a complete prepared diet and the supplements that keep bones strong. Every product is stocked at HardyPaw, so you can build a full feeding routine in one place.
Here is what actually belongs in the bowl, and why.
Key Takeaways
What Your Bearded Dragon Needs Before You Shop
Bearded dragons are omnivores, so their diet changes a lot as they grow. Babies and juveniles are building bone and muscle fast, so they need protein at almost every meal. Adults slow down and shift toward plants, with insects becoming more of a supporting player.
A quick guide to keep in mind:
- Baby (0 to 5 months): roughly 80% insects, 20% greens, fed several times a day.
- Juvenile (5 to 18 months): about a 50/50 split, fed once or twice a day.
- Adult (18+ months): roughly 25% insects, 75% plants, fed once a day or every other day.
Two rules matter no matter the age. Never feed anything wider than the space between your dragon's eyes, since oversized prey can cause choking or impaction. And dust feeders with calcium, because a beardie's biggest dietary risk is metabolic bone disease (MBD).
With that settled, here are the ten foods worth stocking.
The 10 Best Foods for Your Bearded Dragon
1. Live Crickets
Live crickets are the classic staple feeder, and for good reason. They are high in protein, widely accepted by even picky dragons, and their movement triggers natural hunting behavior that keeps your pet active and mentally engaged. Gut-load them for 24 hours and dust with calcium right before feeding to turn a good feeder into a great one. Choose a size that matches your dragon so you stay inside the eye-width rule.
Best for: All ages.
2. Dubia Roaches
If you want a daily staple that outperforms crickets on nutrition, reach for dubia roaches. They carry more protein and meat per bug, less fat, and a better meat-to-shell ratio, which means more usable nutrition per feeding. They also do not smell, chirp, or escape easily. For most owners, dubia roaches for bearded dragons are the easiest staple to keep and feed.
Best for: All ages.
3. Black Soldier Fly Larvae (Grubs)
Black soldier fly larvae, often sold as grubs or calci-worms, are one of the few feeders with a naturally strong calcium-to-phosphorus ratio. That makes them a smart pick for growing juveniles and any dragon you want to support against MBD. The canned format keeps them ready to serve with none of the upkeep of live insects.
Best for: All ages, especially juveniles.
4. Silkworms
Silkworms are soft-bodied, hydrating, and packed with nutrients while staying low in fat. They are gentle on digestion, which makes them a great option for a dragon that is recovering, shedding, or simply being fussy about food. Rotate them in when you want variety without adding extra fat to the diet.
Best for: All ages.
5. Superworms
Superworms are high in protein and high in fat, which makes them a treat rather than a daily food. Use them to help an underweight dragon gain condition or to rebuild reserves after brumation. Feed them in moderation and stick to the eye-width rule, since superworms run large.
Best for: Adults and larger juveniles, in moderation.
6. Canned Cockroaches
Variety keeps a dragon interested and covers more of the nutritional bases, and canned cockroaches are an easy way to add it. They deliver solid protein in a shelf-stable can, so you can offer a different feeder on rotation without keeping another live colony. Think of them as a reliable change of pace.
Best for: All ages, as a rotation feeder.
7. Complete Prepared Omnivore Diet
For the plant side of an adult's diet, a prepared omnivore diet gives you a fortified, ready-to-serve base. It is handy on days when fresh greens are running low, or as a consistent foundation you build fresh produce on top of. It does not replace variety, but it makes the plant portion far easier to hit.
Best for: All ages.
8. Bearded Dragon Pellets
Fortified pellets round out an adult's routine with added vitamins and minerals in a shelf-stable form that portions easily. They work best as a supplement to fresh food rather than a sole diet, and most dragons take to them more readily when the pellets are lightly rehydrated. Keep them as one part of a varied plate.
Best for: Adults, as a supplement.
9. Calcium and Vitamin D3 Supplement
A calcium supplement with D3 is the single most important thing you add to the bowl. Dusting feeders keeps calcium levels where they need to be and is your main defense against metabolic bone disease. Follow your vet's guidance on how often to dust, since it varies with age and your setup's UVB lighting. This one is a mealtime essential, not an optional extra.
Best for: All ages.
10. Multivitamin and Gut-Load Formula
A reptile multivitamin or gut-load formula fills the small nutritional gaps that even a good feeder rotation can leave behind. Used once or twice a week, a multivitamin covers trace micronutrients, while a gut-load boosts the value of the crickets and roaches you feed. Together, they complete a plan.
Best for: All ages.
How Often and How Much to Feed
Matching food to life stage is what turns a good grocery list into a healthy dragon. Use this as a quick reference:
|
Life stage |
Insects |
Plants |
Frequency |
|
Baby (0 to 5 mo) |
~80% |
~20% |
3 to 5 times/day |
|
Juvenile (5 to 18 mo) |
~50% |
~50% |
1 to 2 times/day |
|
Adult (18+ mo) |
~25% |
~75% |
Once a day to every other day |
Dust insects with calcium at most feedings for babies and a few times a week for adults, and always keep fresh water available.
Tip: Chop greens small and serve them in a shallow dish separate from live feeders. Salad set out early in the day, once your dragon has warmed up under its basking light, gets eaten far more readily than food offered when the tank is still cold.
Foods to Avoid
A few foods do real harm, so keep these off the menu:
- Fireflies and lightning bugs, which are toxic to reptiles
- Avocado and rhubarb
- Wild-caught insects, which can carry pesticides and parasites
- Iceberg lettuce, which offers almost no nutrition
- Large amounts of high-oxalate greens like spinach
When you are unsure whether something is safe, check with a reptile veterinarian before offering it.
Building the Right Diet Is Simple
Feeding a bearded dragon well comes down to three habits: rotate a couple of staple feeders, serve the right ratio of plants for your dragon's age, and dust with calcium. Do that consistently, and you support strong bones, good energy, and rich color for years. You can stock every food on this list, from live feeders to supplements, in the bearded dragon and reptile food range at HardyPaw, with fast delivery and autoship savings to keep the bowl full.
Frequently Asked Questions
Q1: What is the best food for a bearded dragon?
Ans: The healthiest diet rotates staple feeder insects like crickets and dubia roaches, adds leafy greens and vegetables, and includes calcium supplementation. No single food covers everything, so variety across protein and plants is what keeps your dragon balanced.
Q2: What do baby bearded dragons eat compared to adults?
Ans: Babies eat mostly insects, around 80% of their diet, to fuel rapid growth and bone development. Adults flip that ratio and eat mostly plants, around 75%, with feeder insects offered as a smaller supporting portion of each meal.
Q3: How often should I feed my bearded dragon?
Ans: Babies eat several times daily, juveniles once or twice a day, and adults once daily or every other day. Adjust the frequency based on activity, body condition, and season, as appetite naturally dips before and during brumation.
Q4: Can bearded dragons eat superworms and mealworms every day?
Ans: No. Both are high in fat and work best as occasional treats rather than staples. Use lower-fat options like dubia roaches or crickets for daily feeding, and save superworms for weight gain or brumation recovery.
Q5: Do I need to dust food with calcium?
Ans: Yes. Dusting feeder insects with a calcium and D3 supplement is the primary way to prevent metabolic bone disease, one of the most common and serious health problems seen in captive bearded dragons. Follow your vet's dosing guidance.
Q6: What foods are toxic to bearded dragons?
Ans: Avoid avocado, rhubarb, fireflies, and wild-caught insects, which can carry pesticides or parasites. Skip iceberg lettuce, too, since it adds water and bulk without meaningful nutrition. When unsure about any new food, check with a reptile veterinarian first.
Q7: Where can I buy safe bearded dragon food online?
Ans: HardyPaw stocks staple feeders, treats, complete diets, and supplements for bearded dragons in one place. Browse the reptile food collection to build a full routine, with reliable sourcing, fast delivery, and autoship savings to keep the bowl full.
