What is the cornerstone of a healthy crested gecko diet providing precise nutrition?

Commercially prepared, nutritionally complete meal replacement powder (CGD)

The cornerstone of a healthy diet for crested geckos is identified as a commercially prepared, nutritionally complete meal replacement powder, often abbreviated as CGD. This manufactured food is essential because it supplies the exact, precise balance of proteins, vitamins, and minerals required daily for the gecko to thrive. These powders were specifically engineered to mimic the nutritional profile observed in the wild diet, incorporating necessary sugars usually derived from fruit, as well as vital micronutrients sourced from elements like pollen and nectar. Whole, unprocessed fruits alone cannot reliably guarantee this required nutritional completeness, making the CGD the staple food source, comparable in importance to balanced kibble for other pets.
