Why is calcium important in a tortoise’s diet?

Calcium is essential for shell strength, bone development, and overall health in tortoises. A calcium deficiency can lead to metabolic bone disease, soft shells, and poor growth. Calcium is best provided through natural food sources and supplements like cuttlebone or calcium powder. Proper UVB lighting is also necessary, as it helps tortoises absorb calcium efficiently. A balanced calcium intake supports long term skeletal health.
