Simply the best calcium product for your captive reptiles. 

Calcium deficiency is a major dietary problem with captive reptiles and amphibians. Maintaining a correct
calcium:phoshorous (Ca:P) ratio in the diet of 1:1 to 1.5:1 is equally important nutritionally as adequate
calcium intake. Commonly used food sources such as Crickets, Meal Worms and Mice contain high levels of
Phosphorous and low levels of calcium.  Australian Calcium assists in balancing the Ca:P ratio by providing a natural phosphorous free calcium source together with vitamin D3 to assist in absorption from the intestinal
tract.

Australian Calcium is manufactured from natural oyster shell ground to a ultrafine powder with added vitamin D3.

Active Constituents:
350mg/g Calcium (as Calcium Carbonate)
