Supplements guide · Australia

Dust smarter, not more.

Supplements are the cheap part of keeping reptiles and the part most often done by guesswork. A simple routine, matched to your lighting, prevents both deficiency and overdose.

Buying guideUpdated October 2026Written for Australian keepers

Snakes eating whole prey

What each powder does

Calcium builds bone and shell. Vitamin D3 lets the body use calcium — your UVB light helps make it naturally. Multivitamins cover vitamin A and trace minerals insects lack.

Dust lightly, then feed fast

Shake insects in a container with a pinch of powder until they look lightly dusted, then feed straight away before it falls off. Gut-load insects for 24 hours beforehand with greens and a quality insect diet.

Common mistakes

  • Leaving a dish of calcium with D3 in the enclosure — D3 can be overdosed.
  • Using a multivitamin every feed.
  • Relying on supplements to fix poor UVB.
  • Storing powders in a humid spot where they clump and degrade.

Questions keepers ask

How often should I dust crickets for a bearded dragon?

Many keepers dust most feeds for juveniles with plain calcium, use calcium with D3 once or twice a week and a multivitamin weekly. A reptile vet can tailor it.

Do blue-tongues need calcium?

Yes — dust insect and some plant portions, especially for growing animals, alongside good UVB.

Can you overdose calcium?

Plain calcium is hard to overdo; vitamin D3 and vitamin A can be overdosed, which is why schedules matter.
