TC Calcium – Ultra-Fine No D3 is a 3 oz calcium powder designed for reptile keepers who dust feeder insects before mealtime. The ultra-fine texture helps the powder cling to smooth feeder surfaces, making it easier to lightly coat Dubia roaches, crickets, mealworms, superworms, hornworms, red runner roaches, and other feeder insects.
Use this no-D3 calcium option when your animal’s care plan already accounts for vitamin D3 through proper UVB exposure, diet, or a separate supplement recommended for the species. Dusting should be light: place feeders in a cup or bag, add a small amount of powder, gently shake until coated, then feed right away. Avoid over-coating feeders or leaving dusted insects in the enclosure for long periods.
Calcium powder is one part of good feeder nutrition, not a replacement for species-appropriate husbandry, gut-loading, hydration, UVB lighting, or veterinary guidance. For many insect-eating reptiles, feeder insects naturally need calcium support, and keepers commonly combine gut-loaded insects with careful dusting.
Pair TC Calcium with live feeders from TC Insects, including Dubia roaches, live crickets, mealworms, superworms, hornworms, and red runner roaches. Store the jar closed in a cool, dry place, and check your reptile’s species-specific feeding schedule before choosing a calcium, multivitamin, or D3 routine.
FAQ’s
Does TC Calcium contain D3?
No. TC Calcium Ultra-Fine is a no-D3 calcium powder. Use it as part of a species-appropriate supplementation plan, especially when vitamin D3 needs are already addressed through UVB, diet, or a separate supplement.
How do I dust feeder insects with calcium powder?
Place feeder insects in a cup or bag, add a small amount of calcium powder, gently shake until lightly coated, and feed soon after dusting.
Does calcium powder replace gut-loading?
No. Calcium dusting should be used alongside proper feeder care, gut-loading, hydration, and species-specific reptile husbandry.
