How much should you feed?

Bearded dragons are omnivorous desert lizards whose diet flips as they grow: babies are insect-hungry protein machines, while adults eat mostly leafy greens and vegetables. Getting the insect-to-greens ratio right for the age is the single most important feeding decision.

Frequently asked questions

How much should I feed a bearded dragon?

Babies eat mostly insects (as many as eaten in 5-10 minutes, two to three times daily) plus some greens; adults eat mostly greens daily with insects only 3-5 times a week. Use the calculator to estimate insect counts by weight.

What do bearded dragons eat?

A mix of gut-loaded, calcium-dusted insects (dubia roaches, crickets, BSFL) and leafy greens and vegetables. The ratio shifts from insect-heavy in babies to greens-heavy in adults.

How often do adult bearded dragons eat insects?

About 3-5 times a week, alongside a fresh salad every day. Feeding adults insects daily leads to obesity.

Why does my bearded dragon need calcium powder?

To prevent metabolic bone disease. Dusting gut-loaded insects with calcium and vitamin D3, combined with proper UVB lighting, ensures the dragon can build and maintain healthy bone.
