Vitamin D Program
A four-tier vitamin-D3 line — High, Medium, Low and No-D — so you match supplementation to a species' UV exposure instead of over- or under-dosing a single formula.
High · Medium · Low · No-D tiers

The manual · ZC-D
Most supplements ship one D3 level and hope. A UV-flooded bearded dragon and a fossorial, UV-shy species have opposite needs — and the wrong dose causes metabolic bone disease or D3 toxicity.
Our program splits D3 into four matched tiers — High, Medium, Low and No-D — so the keeper dials supplementation to the animal's real UV exposure. The flagship of the Kirkland line.
