Fluker's Calcium with D3 4oz - Pack of 10 Reptile Supplement for Healthy Bones

Calcium supplementation is one of the most important — and most overlooked — parts of reptile husbandry. This 10-pack of Fluker's Calcium with Vitamin D3 gives you a reliable supply of one of the hobby's most trusted supplements, so you're never caught without it.

What it is

Fluker's Calcium with D3 is a fine-powder calcium carbonate supplement fortified with Vitamin D3. It's designed to be dusted directly onto feeder insects or fresh produce before feeding.

What it's used for

Calcium is essential for bone development, muscle function, and metabolic health in reptiles. Vitamin D3 is required for calcium absorption — particularly important for animals that don't receive adequate UVB lighting or are kept in setups where natural D3 synthesis may be limited.

May be appropriate for

• Bearded dragons, leopard geckos, crested geckos, and other insectivores
• Omnivorous species that eat dubia roaches, crickets, or hornworms
• Reptiles in bioactive or low-UVB enclosures where D3 supplementation is part of the care plan

Specs

• Size: 4 oz per container
• Pack of 10 — ideal for breeders, multi-animal keepers, or stocking up
• Active ingredient: Calcium carbonate with added Vitamin D3

Husbandry notes

Dust feeders lightly just before offering — a thin coating is all that's needed. Over-supplementation of D3 can be harmful, so follow a schedule appropriate for your species and lighting setup. If your enclosure provides strong UVB (T5 HO 10.0 or equivalent), consult your care guide on whether a D3-free calcium should be alternated in rotation.

Always research the specific supplementation needs of your species. When in doubt, consult a reptile-experienced veterinarian.
