Repashy SuperCal NoD is a calcium supplement designed for reptiles and amphibians, especially those exposed to UVB light and who do not require additional vitamin D3 supplementation. "NoD" stands for "No D3" , which means this product does not contain vitamin D3, in contrast to other calcium supplements such as Calcium Plus , which contain vitamin D3 to aid in calcium absorption.
 SuperCal NoD is therefore ideal for reptiles that have sufficient exposure to UVB light, which allows them to synthesize their own vitamin D3 and absorb calcium naturally. This supplement is designed to provide only calcium , without the risk of vitamin D3 overdose, which is especially important for reptiles like crested geckos, bearded dragons, or other species that benefit from exposure to UVB light.
