Metabolic bone disease (MBD) is one of the most serious and common health problems seen in captive reptiles and amphibians. It causes pain, deformity, weakness, and in severe cases, death — yet in almost all cases it is entirely preventable. The Arcadia Guide to MBD and Its Elimination in Captivity is a clear, practical, and scientifically grounded book designed to help keepers understand exactly what MBD is, why it happens, and how to stop it. This full-colour hardback explains the biological role of calcium, vitamin D₃, and UVB lighting in reptile health, showing how incorrect lighting, poor diet, or hydration can disrupt bone development and lead to disease. Rather than relying on outdated myths or guesswork, the book presents modern, evidence-based husbandry principles that can be applied in real home vivariums. It covers diet, hydration, supplementation, lighting technology, and enclosure design in a way that is easy to understand and put into practice. Written by Arcadia Reptile — one of the world’s leading authorities on reptile lighting and welfare — this guide provides a reliable framework for preventing MBD and supporting long-term skeletal health in captive reptiles and amphibians. Whether you are caring for a bearded dragon, gecko, snake, amphibian, or any other captive species, this book gives you the knowledge needed to create a safer, healthier environment and avoid one of the most damaging conditions in reptile keeping.
