Calcium is an important mineral supplement for reptile and amphibian health. Calcium is necessary for proper lizard bone growth and the prevention of metabolic bone disease, for viable egg production, nerve function, and hormone synthesis.
Calcium for reptiles is available in several forms -
Reptile calcium powder made from phosphorous-free oyster shell calcium carbonate is made to be sprinkled on food.
Liquid calcium for lizards is for dispensing into water or food, or directly into the animal's mouth.
Calcium sprays for reptiles are designed to be sprayed on foods.
