Calcium Plus HyD is the high-D3 version of Repashy's all-in-one dusting powder, formulated for animals that receive little or no UVB exposure and therefore depend entirely on dietary vitamin D3 to metabolise calcium.
When HyD Is the Right Choice
Vitamin D3 lets reptiles and amphibians actually use the calcium in their diet. Animals under good UVB lighting synthesise their own D3 through their skin; animals without UVB cannot, and need it supplied in food. HyD exists for exactly these setups: nocturnal and crepuscular species traditionally kept without UVB (leopard geckos, fat-tailed geckos, many amphibians), rack-based breeding collections, and any enclosure where UVB provision isn't practical.
If your animals are under strong UVB, HyD is the wrong choice — combining high dietary D3 with full UVB synthesis risks oversupplementation. Use the standard Calcium Plus or the LoD version instead.
How to Use
Identical to the standard formula: lightly coat feeder insects by shaking them gently with powder in a bag or cup, and feed immediately. Use at every insect feeding — the formula is balanced for everyday use, not weekly rotation. It carries the same complete vitamin and trace element profile as standard Calcium Plus, including vitamin A as both retinol and carotenoids.
Common Applications
Leopard gecko keepers are the classic HyD users — a hugely popular species, most often kept without UVB, and prone to metabolic bone disease when D3 supplementation is missed. Amphibian keepers feeding dusted crickets or fruit flies to frogs without UVB are the other major group. If you culture your own feeder insects or feeder roaches, HyD is the final dusting step before feeding for no-UVB setups.
Ideal for: leopard and fat-tailed geckos without UVB; amphibian collections; rack systems; any insectivore kept without UVB lighting.
Not ideal for: animals under strong UVB — use Calcium Plus LoD.
