Metabolic Bone Disease/Calcium Deficiency in Reptiles

Calcium deficiency in reptiles, also known as Metabolic Bone Disease or MBD, is very common in reptiles, especially if the keeper is inexperienced. All reptiles require a calcium supplement or a UV lamp and sometimes both to ensure that they get the proper vitamins they need in captivity. In the wild they would get these vitamins from sunlight and a more varied and natural diet, but in captivity it's a different story.

Some signs of a calcium deficiency are lethargy, kinky tails, deformed jaw, floppy tail, and brittle bones. Reptiles with an extreme deficiency may also spasm and even become paralyzed in some or all limbs. If they don't get the calcium they need, they will eventually die.

Breeding females are more susceptible to MBD because of the calcium they use up producing eggs. Calcium supplement should always be regularly given to breeding females.

To prevent a MBD in your pet, make sure your reptile is getting a calcium supplement at least every other day either dusted on crickets or sprinkled on its veggies or fruits (depending on your species and its required food).

If your pet already has a calcium deficiency, boost the intake. You can mix some calcium with water and feed with a syringe. Also try special calorie boosting products like Repta-aid. If you don't see a marked improvement in a few days or if it is very serious, visit a reptile vet immediately.
