Reptile World Calcium with added D3 is a great way to help support your reptile's/amphibian's calcium intake. Your reptile/amphibian needs calcium to grow and develop a healthy skeletal structure and the Vitamin D3 in this mix does just that. Vitamin D3 helps assimilate the calcium into the body of your reptile/amphibian. This supplement contains both calcium and D3, giving them everything they need to keep MBD (metabolic bone disease) at bay. We also highly recommend using a UV D3 light as an essential, as it helps assimilate even further. There should be no phosphorous contribution from this supplement, as the calcium is phosphorous free.
