Are Mealworms Good for Bearded Dragons?
Mealworms are one of the most common feeders offered to bearded dragons, but "common" doesn't automatically mean "ideal." Whether they're a good fit depends on your dragon's age, how often you feed them, and whether you're pairing them with proper supplementation.
This guide breaks down exactly where mealworms fit into a bearded dragon's diet. For general mealworm care, see our mealworm care guide.
Quick answer: Mealworms are fine for adult bearded dragons as part of a varied diet, but they're a poor choice as a primary staple due to their tough exoskeleton and poor calcium-to-phosphorus ratio — and they're generally not recommended for young juveniles at all.
The Calcium Problem
Mealworms carry a notably phosphorus-heavy calcium-to-phosphorus ratio compared to feeders like crickets or woodies. Bearded dragons need more calcium than phosphorus in their overall diet to avoid metabolic bone disease, so mealworms fed without calcium dusting work against that balance rather than toward it. Dusting every feed largely offsets this.
The Exoskeleton Concern
Mealworms have a noticeably tougher, more chitin-heavy exoskeleton than crickets or woodies. This is harder for a bearded dragon to digest, and it's the main reason mealworms aren't recommended for young juveniles, whose digestive systems are still developing. Adults tend to handle it without issue.
Age Matters
Avoid mealworms for hatchlings and young juveniles — stick to softer-bodied feeders like appropriately sized crickets or woodies until your dragon is more established. Sub-adults and adults can handle mealworms comfortably, and by adulthood mealworms make a reasonable occasional feeder.
Young dragons can also get 'hooked' on mealworms. Causing them to become picky eaters, and limiting them to a less-than-ideal feeder option.
Staple or Occasional Feeder
Given the calcium ratio and exoskeleton toughness, as well as being a more fatty feeder, mealworms are better used as one part of a rotating diet rather than the main feeder. Pairing them with crickets or woodies as staples, and keeping mealworms as a regular but secondary option, gets the convenience without the nutritional downsides of relying on them alone.

Final Thoughts
Mealworms are suitable for adult bearded dragons in moderation, as part of a varied diet, when dusted regularly. But they're not the feeder to build a whole diet around, and they're not appropriate for young juveniles. Used with that in mind, they're a genuinely convenient addition to the rotation.
