What do Bearded Dragons eat?

However, as a bearded dragon gets older, you’ll need to reduce the amount of meat he’s eating. As he won’t be getting as much exercise as his wild cousins. Consequently, feeding him too much meat can lead to obesity.

What can’t Bearded Dragons eat?

Iceberg lettuce 

It’s mostly water and as a result, has little nutritional value. So don’t let your Bearded Dragon eat it

Spinach and beet tops 

Some guides will say these are fine for bearded dragons, and they can be in small quantities. However, both contain chemicals that can cause calcium deficiency, which in turn can lead to metabolic bone disease.

However, an occasional taste shouldn’t harm a bearded dragon. But with so many other options available it may be best to choose different greens

Insects captured in the wild

Wild insects may have parasites in them as a result, harming the reptiles.


Bearded Dragons are not supposed to eat this, or any other reptile. In fact, any insect that glows is most probably toxic and can kill reptiles


Chemicals in avocados are toxic for bearded dragons. As a result, a small amount will make reptile ill and a large portion can be fatal


High levels of oxalic acid in rhubarb can be deadly poisonous for bearded dragons

Dubia Roaches

Dubia roaches are one of the best staple insects for bearded dragon in the wild. They are

  • rich in protein
  • low in fat content, and
  • provide an array of valuable nutrients.

Furthermore, this insect feeder is very easy for bearded dragons to digest and come in different sizes depending on its life stage.

Also, they are easy to care for and offer some advantages over crickets:

  • they are quiet and do not make any noise
  • are not as smelly as crickets
  • easily bred for a continuous supply of quality insect feeders
  • cannot climb which makes it nearly impossible for them to escape

  • Protein – 36%
  • Fat – 7%
  • Ash – 2%

Goliath Worms

Goliath worms (or Horned worms) are another excellent choice as a staple insect feeder for your bearded dragons.

These worms can rapidly grow four to five inches in length and are a good source of protein. They typically come in large cups pre-loaded with food and contain mostly 15 – 25 worms.

These worms grow very quickly and bearded dragons feed on them after a couple days growth.

  • Protein – 9%
  • Fat – 3%
  • Calcium – 46.4mg/100mg

Wax Worms

Waxworms are small white-colored worms that are an excellent occasional treat insect for bearded dragons in the wild. However, these worms ought not to be a staple food item, because they tend to be high in fat content.

Naturally, adult bearded dragons are not supposed to eat more than five to six wax worms per day. Because eating too many wax worms can lead to obesity issues later in the bearded dragon’s life.

Nutritional Information

  • Moisture Content – 61%
  • Protein – 15%
  • Fat – 21%
  • Calcium – 28.3mg/100mg


These are a very popular bearded dragon feeder insect. They can grow to a length of about two inches in length and contain a hard outer shell called chitin. Thus, young bearded dragons can have a difficult time digesting the chitin. Therefore, adult bearded dragons should not feed on mealworms only due to the risk of impaction.

Likewise, adult bearded dragons should only eat mealworms (very large mealworms are sometimes called Superworms) as a supplement to staple insects. Five to six mealworms per feeding for an adult bearded dragon ought to be fine.

Nutritional Information

  • Moisture Content – 62%
  • Protein – 20%
  • Fat – 13%
  • Calcium – 13.3mg/100mg


Crickets offer a good amount of protein and calcium. In fact, they are arguably the most well-known feeder insect for bearded dragons.

However, bearded dragons can have some difficulty digesting crickets due to hard body parts, such as the hind legs.

  • Moisture Content – 69%
  • Protein – 21%
  • Fat – 6%

Phoenix Worms (Black Soldier Fly Larvae)

Firstly, these (Black Soldier Fly Larvae are the same thing) are a very good feeder insect for bearded dragons. They have high levels of protein and calcium to offer. Furthermore, they are easy to keep. Also, Phoenix worms are a very good supplemental insect for bearded dragon’s diet.

Due to their very small size, it can be impractical for bearded dragons to have them as a staple food.

Nutritional Information

  • Moisture Content – 68%
  • Protein – 15.5%
  • Fat – 8%
  • Calcium – 43mg/100mg


These are another very small worm (about one inch in length) that offers good amounts of protein and high levels of calcium.

This small nutritious worm is indeed an excellent feeder insect forbearded dragons to have as a supplement.

Nutritional Information

  • Moisture Content – 58.5%
  • Protein – 16%
  • Fat – 5%
  • Calcium – 87mg/100mg

Nutritional Information

  • Moisture Content – 76%
  • Protein – 64%

Locusts are an excellent feeder insect for a bearded dragon to feed on. Thus, they offer high amounts of protein and are relatively low in fat.

Vitamin and Mineral Supplements


Indeed, most commercially raised feeder insects are deficient in calcium. And also, as regards greens, the ability to absorb calcium from different plants sometimes may vary. That is why calcium is an essential supplement for bearded dragon.

Calcium to Phosphorus Ratio

For proper metabolism, it is important to always strive for 1:1 calcium to phosphorus ratio. If you study the nutritional charts, you will notice that many foods, especially feeder insects, have an unbalanced Ca : P ratio. That makes calcium supplementation even more important.

Vitamin D3

Firstly, for a bearded dragon to metabolize calcium, he will need sufficient doses of vitamin D3. Thus, vitamin D3 is actually a hormone-like substance. Which the body synthesizes when it becomes exposed to sunlight. Generally, that is one of the reasons that diurnal lizards bask so often.


This is an element that might be lacking in bearded dragon’s menu in the wild. However, the question of iron is somewhat tricky. A lot of dark leafy greens such as

  • Kale
  • spinach and
  • charts contain desirable levels of it. But at the same time, they contain high amounts of dangerous oxalates.

Vitamin A

Of course, this is very commonly seen in many vegetables and leafy greens in the form of beta-carotene. Therefore, within the body, beta-carotene converts to vitamin A as needed, and the excess flushes out.
