Walk into a pet store looking for bearded dragon food and you’ll find three shelves of options that all claim to be “complete nutrition.” Most aren’t. Some are padded with filler ingredients your beardie can’t digest well. Others are fine as an occasional supplement but disastrous as a staple. This guide covers what to actually buy (feeder insects, greens, commercial pellets) and how to tell a decent product from a bag of marketing.

What to Actually Buy: The Short List

Skip the overwhelm. Here’s what a properly stocked bearded dragon feeding setup actually needs:

• Staple feeder insect: dubia roaches (best) or crickets (close second)
• Calcium powder without D3 (Repashy Calcium Plus LoD or Zoo Med Repti Calcium) for daily dusting
• Calcium powder with D3 for twice-weekly dusting if your UVB setup is borderline
• Fresh greens: collard greens, mustard greens, dandelion greens, turnip greens (rotate, don’t rely on one)
• Occasional treats: squash, bell pepper, small amounts of fruit
• Optional pellets: Zoo Med Natural Bearded Dragon Food or Rep-Cal as a supplement, not a base

That’s it. You don’t need the calcium sand, the vitamin gel cups, or half the accessories the “starter bundle” tries to sell you. Our food database covers safety ratings for 200+ individual foods if you’re checking something specific.

Feeder Insects: Dubia vs. Crickets vs. Everything Else

Dubia roaches win on almost every metric that matters. They’re higher in protein relative to fat than crickets, they don’t smell, they don’t chirp all night in your feeder bin, and they can’t jump out and hide in your carpet. The only downside is availability. Some states restrict roach shipping, and a few keepers just can’t get past the visual.

Crickets are the traditional staple and still work fine. They’re cheaper per unit in most regions and available at literally every pet store, which matters if you run out mid-week. The tradeoff: they die fast in a feeder bin (dead crickets aren’t a safety issue, but a beardie won’t chase a dead one, so you waste some), and the noise gets old.

Black soldier fly larvae (sold as Phoenix worms or NutriGrubs) are worth rotating in since they’re naturally calcium-rich, which cuts down on how much dusting you need. Superworms and mealworms exist but have a harder exoskeleton (chitin) that’s tougher to digest; use them as occasional treats, not a staple, and never for juveniles under 4 months.

Buy feeders in bulk from a dedicated supplier. Dubia.com, Josh’s Frogs, and Fluker’s Cricket Farm all ship live insects with reasonable survival rates. Ordering 500 dubia roaches costs less per roach than buying 20 at a time from a pet store, and you’ll always have feeders on hand.

Greens and Vegetables: The Bulk of the Diet

This is where most new owners underinvest. Insects get all the attention because they’re more visually engaging to feed, but greens should make up the majority of an adult beardie’s plate by volume.

Rotate between collard greens, mustard greens, turnip greens, dandelion greens (if pesticide-free), and endive. Kale and spinach are fine in small, occasional amounts, not as a daily base, since both bind calcium when overfed. Iceberg lettuce is nutritionally close to water; skip it entirely.

Chop greens small. Roughly the width between your beardie’s eyes is the standard sizing rule, and it applies to vegetables just as much as insects. Large, unchopped leaves get ignored or, worse, swallowed in chunks that cause impaction risk.

Commercial Pellets: Useful Supplement, Bad Staple

Pellets are convenient, shelf-stable, and genuinely useful as maybe 10-15% of the diet, not the backbone of it. The problem with pellet-heavy feeding is texture and behavior: bearded dragons are visually-triggered hunters, and a bowl of static pellets doesn’t stimulate the same feeding response as live insects or fresh greens. Beardies raised on mostly pellets sometimes become picky about everything else.

Here’s what new owners often miss: ingredient order matters more than the “complete nutrition” label on the front of the bag. If you use pellets, look for ones where a named protein (not “meat meal”) is the first ingredient, and avoid anything padded heavily with corn or soy filler. Zoo Med’s Natural Bearded Dragon Food and Rep-Cal’s adult formula are reasonable picks. Use pellets to bridge a gap (you’re out of crickets for two days), not as the everyday plan.

Gut-Loading and Dusting

An underfed feeder insect passes almost nothing to your beardie. Gut-loading means feeding your feeder insects nutritious food for 24-48 hours before you feed them out. You’re essentially feeding the food that’s about to feed your beardie. Commercial gut-load products (Repashy Bug Burger, Fluker’s High Calcium Cricket Diet) work well, or you can gut-load with the same fresh greens you’re already buying.

Dusting is separate and non-negotiable. Toss feeder insects in a bag or container with calcium powder right before feeding, shake to coat, and serve immediately. Powder that sits on uneaten insects for hours mostly falls off. Juveniles get calcium powder (no D3) at every single feeding. Adults can go every other feeding. Everyone needs a D3-inclusive formula twice a week, unless your UVB setup is a T5 HO tube at the correct distance, in which case natural D3 synthesis covers most of it and over-supplementing D3 becomes the bigger risk.

Food Ratios by Age

These ratios shift gradually, not on a fixed calendar date. Watch your beardie’s growth rate and body condition instead of treating the age brackets as hard cutoffs.

Where to Buy: Online vs. Pet Store

Pet stores work for emergency top-ups and greens (most grocery stores double as your greens supplier, honestly: collard and mustard greens from the produce aisle are identical to reptile-marketed versions at triple the price). For feeder insects and supplements, online specialty suppliers beat big-box pet stores on both price and quality almost every time.

Dubia.com and Josh’s Frogs both ship live insects with live-arrival guarantees. For calcium and gut-load powders, buy directly from Repashy or Zoo Med rather than a generic Amazon reseller. Counterfeit and expired supplement products are a real problem in third-party marketplace listings.

Feeding Mistakes That Cause Problems

A few patterns show up constantly in beardies with feeding-related health issues:

• Insects too large. Nothing wider than the space between your beardie’s eyes. Oversized feeders are a leading cause of impaction.
• Skipping calcium dusting. This is the single biggest contributor to metabolic bone disease, alongside inadequate UVB.
• Overfeeding fruit. Fruit should be an occasional treat, not a regular menu item. The sugar content isn’t what a beardie’s gut evolved for.
• Feeding spinach or kale as a daily base. Both bind calcium in enough quantity to cause deficiency over time, even with good dusting.
• Not rotating greens. One green forever means one narrow nutrient profile forever. Rotate at least 3-4 different greens weekly.

If your beardie has stopped eating altogether, that’s a different problem worth troubleshooting separately. See our guide on what to do when a bearded dragon won’t eat.

The Bottom Line

Dubia roaches or crickets, rotated fresh greens, calcium dusting on a real schedule, and pellets as a supplement rather than a foundation — that’s the whole system. Everything else on the pet store shelf is optional at best. Get the ratios right for your beardie’s age, don’t skip the dusting, and the rest is mostly consistency.
