Bearded dragons are omnivores, which means their diet can include both plant matter and insects. But that does not mean everything in your refrigerator, garden, or backyard is safe for your beardie.
A healthy diet requires variety, proper nutrition, and knowing which foods should be regular staples, which should be occasional treats, and which should be avoided altogether.
Everyday Greens and Vegetables
Leafy greens should play an important role in an adult bearded dragon's diet.
Good choices include collard greens, mustard greens, dandelion greens, and turnip greens. These provide valuable vitamins and minerals and can be rotated to give your beardie nutritional variety.
Vegetables such as butternut squash and bell peppers can also be incorporated into a balanced diet.
As bearded dragons mature, plant foods generally become a larger portion of their diet than they were during the rapid growth of their younger years.
Don't Forget the Insects
Insects provide important protein, particularly for young and growing bearded dragons.
Dubia roaches are a popular feeder because they provide protein without some of the disadvantages associated with fattier feeder insects.
Hornworms can also be offered, particularly as an occasional treat.
Whatever feeder insects you choose, proper sourcing and nutrition matter. Avoid feeding insects collected outdoors because of possible exposure to pesticides, parasites, or other contaminants.
Fruit Is a Treat, Not a Staple
Bearded dragons may enjoy fruit, but enjoying something does not necessarily mean they should eat it every day.
Foods such as blueberries, mango, and strawberries can be offered occasionally and in small amounts.
Think of fruit as a treat rather than a major component of the diet. Too much fruit can add unnecessary sugar and may contribute to nutritional or digestive problems.
Foods Bearded Dragons Should Avoid
Knowing what not to feed your bearded dragon is just as important as knowing what to put in the food bowl.
Avocado should not be fed to bearded dragons.
Fireflies should never be fed. They contain toxins that can be extremely dangerous and potentially fatal to reptiles.
Foods such as onions and garlic should also be avoided.
Iceberg lettuce offers very little nutritional value compared with healthier leafy greens and can contribute to loose stools when consumed in quantity.
Spinach is another food generally best limited or avoided as a regular dietary item because compounds within it can interfere with calcium availability.
Calcium Is Especially Important
Calcium deserves special attention in bearded dragon care.
A proper diet works together with appropriate UVB exposure and husbandry to support healthy bones and normal development. Depending on your beardie's age, diet, health, and veterinary recommendations, feeder insects may need to be appropriately supplemented with calcium.
Long term nutritional deficiencies can contribute to serious health problems, including metabolic bone disease.
Variety Is the Key
There isn't one magical food that creates a healthy bearded dragon.
The goal is an appropriate balance of nutritious greens, vegetables, properly raised feeder insects, occasional treats, and proper supplementation based on the animal's age and needs.
Just as importantly, pay attention to your individual beardie.
Changes in appetite, weight, stool, activity, or eating behavior can sometimes be early indications that something isn't right.
A thoughtful diet is one of the most important things you can provide your bearded dragon throughout its life.
Feed for health, offer variety, and remember that what's safe for us isn't necessarily safe for our reptiles.
