In captive reptiles and amphibians, a significant dietary issue is the deficiency of calcium. It is considered equally important for nutrition to maintain a proper ratio of calcium to phosphorus (Ca:P) of 1.5:1 in their diet, as it is to consume an adequate amount of calcium. Therefore, in most cases, the issue is an incorrect Ca:P ratio rather than insufficient calcium.
If the enclosure of reptiles and amphibians has appropriate UVB lighting, this supplement is suitable for use since it lacks vitamin D3. However, it is not recommended to use this product with reptiles that do not have UVB lighting.
Using a calcium supplement that also adds phosphorous makes no sense, as an adequate Ca:P ratio can never be achieved. Bone meal contains phosphorous.
