Calcium powder with D3: How Bearded Dragons Use It
Frequency
2x per week if using adequate UVB; consult a vet on dosing if not running UVB
Role
Supports D3 synthesis and calcium absorption alongside dietary intake. Because most bearded dragon setups run mandatory UVB, dietary D3 needs are lower than in species kept without it — over-supplementing D3 causes toxicity, so don't stack it with every feeding once UVB is in place.

Calcium powder without D3 is used every insect feeding, and lightly dusted on the daily salad. The primary defence against Metabolic Bone Disease, which remains the most common serious health problem in captive bearded dragons.
Multivitamin powder is used once per week. Provides vitamins and trace minerals not fully covered by gut-loaded insects and fresh produce alone.
D3 adjustment based on UVB strength is used reduce dietary d3 as uvb output increases. Bearded dragons are strongly diurnal, high-UV baskers in the wild and have a real physiological need for UVB — this isn't optional the way it can be for more nocturnal species.
