Frequency
Once per week maximum
Role
Provides vitamins A, B complex, and E that are not present in sufficient quantities in feeder insects even with gut-loading. Vitamin A toxicity is well documented in reptiles — do not exceed weekly use and do not stack multiple supplement products without checking for D3 and vitamin A overlap.

Calcium powder with D3 is used every feeding (juveniles) / every other feeding (adults). Primary defence against Metabolic Bone Disease.
Plain calcium (no D3) is used always available in a small open dish. Many geckos self-regulate calcium intake by licking a small dish voluntarily.
D3 adjustment if using UVB is used reduce d3 supplementation accordingly. Leopard geckos are crepuscular and get limited UV exposure naturally, but captive geckos with proper UVB lighting (5–7% UVB, 10–12 hours/day) will synthesise D3 through their skin.
