Reptile Systems Calcium Ultra

Reptile Systems Calcium Ultra is a high-grade calcium supplement formulated for reptiles, amphibians, and other animals that require reliable dietary calcium support. Ultra-fine, phosphorus-free, and highly bioavailable, it is designed to adhere effectively to feeder insects or be dusted directly onto food items — making supplementation straightforward for keepers at every level. Available in a range of sizes to suit everything from small vivarium setups to larger collections.

Why Calcium Matters

Calcium is fundamental to bone and shell development, muscle function, and a wide range of essential bodily processes. Without consistent, adequate calcium intake, reptiles and amphibians are at genuine risk of Metabolic Bone Disease (MBD) and other hypocalcemia-related conditions. Calcium Ultra is formulated to address this directly, providing a clean, concentrated source that integrates easily into any feeding routine.

Key Ingredients

Calcium Ultra is built around two core compounds:

• Calcium Carbonate — A naturally occurring form of calcium found in limestone and chalk, and the standard bioavailable source used in reptile supplementation. Reptile Systems source a high-grade, impurity-free calcium carbonate to ensure consistent quality and absorption.
• Magnesium Carbonate — An essential mineral that supports calcium absorption and plays a role in regulating nerve and muscle function, as well as hundreds of other biochemical processes. Calcium Ultra contains a balanced level of magnesium specifically calibrated for optimal calcium uptake and storage.
