Zoo Med Repti Calcium with D3

Overview

What it is and who it suits

Zoo Med Repti Calcium with D3 is a finely milled phosphorus-free calcium supplement formulated specifically for reptiles and amphibians kept in captivity, where natural sunlight and varied wild diets are unavailable. Because captive reptiles cannot always synthesize or obtain adequate calcium through diet alone, this powder is designed to be lightly dusted onto feeder insects, greens, or other food items before offering them to your pet. The inclusion of vitamin D3 is essential, as it allows reptiles to properly absorb and utilize the calcium even when exposure to UVB lighting is limited, making it a practical solution for indoor enclosures and a wide range of species including bearded dragons, leopard geckos, chameleons, turtles, and tortoises.

Calcium deficiency is one of the most common and preventable health issues in pet reptiles, often leading to metabolic bone disease, soft or deformed shells, muscle tremors, and lethargy. Zoo Med Repti Calcium with D3 directly addresses this risk by providing a concentrated, bioavailable source of calcium that supports strong skeletal development, proper nerve and muscle function, and healthy shell formation in chelonians. The phosphorus-free formula is particularly important because excess phosphorus can interfere with calcium absorption, so this supplement helps maintain the correct calcium-to-phosphorus ratio that is critical for long-term reptile health, especially for growing juveniles and reproductively active females who have elevated calcium demands.

Packaged in a resealable shaker-top container, this supplement is easy to incorporate into a regular feeding routine, allowing keepers to lightly coat crickets, mealworms, dubia roaches, or chopped vegetables with a fine, adhesive powder that reptiles readily consume along with their food. Zoo Med, a trusted name in herpetological care products, designed this formula to be used several times a week depending on species-specific needs and existing UVB exposure, making it a staple in comprehensive reptile husbandry. Whether you're maintaining a desert-dwelling lizard, a tropical gecko, or an aquatic turtle, Repti Calcium with D3 serves as a foundational supplement that helps replicate the nutritional balance these animals would naturally obtain in the wild, supporting long-term vitality and reducing the risk of diet-related health complications.
