Q: Do Crested Geckos Need Calcium Powder If They Eat a Complete CGD Diet?

Crested geckos eating a complete gecko diet (CGD) like Repashy or Pangea don't need extra calcium powder added to the food — those diets are already formulated with the right calcium and vitamin D3 levels. That said, if live feeder insects are part of the rotation, you still need to dust those insects lightly with calcium powder before every feeding.

Q: Should I Use Calcium Powder With D3 or Without D3 for My Crested Gecko?

If your crested gecko has no UVB lighting, use calcium powder with vitamin D3 — D3 is required for calcium to actually absorb. If your gecko has a proper UVB lamp, go with calcium powder without D3 . The light produces D3 naturally through the skin, and layering extra D3 on top through supplements builds up a risk of vitamin D3 toxicity over time.

Q: How Often Should I Dust Feeder Insects With Calcium Powder for a Crested Gecko?

For baby and juvenile crested geckos under 12 months old, dust feeder insects at every single insect feeding . Adults need dusting 2 to 3 times per week . Breeding females are in a category of their own — egg shell production demands a significantly higher calcium intake. That means dusting every insect feeding and keeping a separate dish of plain calcium without D3 available at all times so they can self-regulate.

Q: What Happens If You Give a Crested Gecko Too Much Calcium Powder?

Too much calcium powder leads to hypercalcemia — blood calcium rising to abnormally high levels, which is genuinely dangerous. What makes it tricky is that calcium overdose symptoms look nearly identical to deficiency: wavy tail , muscle weakness , lethargy , and loss of appetite . Excess vitamin D3 on top of that compounds the damage by putting stress on the kidneys and soft tissues .

Q: What Are the Signs of Calcium Deficiency in Crested Geckos?

Calcium deficiency in crested geckos shows up as a soft or rubbery jaw , spine curvature , swollen limbs , trembling , and in serious cases, inability to walk . The calcium sacs on the roof of the mouth go pale and flat . Left unchecked, the progression leads to Metabolic Bone Disease (MBD) , which causes permanent bone deformities and can be fatal.

Q: Do Breeding Female Crested Geckos Need More Calcium Powder Than Males?

Yes — breeding females need significantly more calcium than males . Every egg requires a substantial amount of calcium to form a proper shell, and females that aren't getting enough supplementation run real risks: egg binding , soft-shelled eggs , brittle bones , and long-term skeletal damage . Breeding females should be getting calcium supplementation 3 to 4 times per week .

Question 7

Can You Leave Calcium Powder in a Crested Gecko's Enclosure for Them to Eat Freely?

Accepted Answer

You can absolutely leave a small dish of calcium powder in the enclosure for free-feeding — just make sure it's plain calcium without vitamin D3. Because you have no control over how much your gecko consumes from a free-feed dish, putting D3 calcium in there creates a slow-building risk of vitamin D3 toxicity that compounds over time.
