Leopard geckos need calcium to build strong bones and prevent metabolic bone disease. When it comes to picking a calcium supplement, a common question is whether to choose one with or without vitamin D3.
If you’re short on time, here’s the quick answer: go with a calcium powder that contains D3 twice a week, and use a D3-free calcium 5 days a week.
In this comprehensive article, we’ll cover everything you need to know about leopard gecko calcium and D3. You’ll learn about the role of calcium and vitamin D, how much to use, and recommendations for the best calcium powders for your pet.
The Role of Calcium for Leopard Geckos
Supporting Bone Health
Calcium is crucial for leopard geckos to maintain proper bone health and prevent metabolic bone disease (MBD). Here are some key reasons why calcium is so important:
- Calcium makes up a large part of a leopard gecko’s skeletal structure. It gives their bones strength and rigidity.
- Calcium is essential for normal bone growth and development in young, juvenile leopard geckos.
- Adult leopard geckos also need calcium to maintain and repair their bones as needed.
- A calcium deficiency can lead to soft, brittle bones that are prone to fractures and deformities.
Leopard geckos get calcium primarily from their feeder insects. Crickets, mealworms, dubia roaches and other feeders naturally contain some calcium in their bodies. But the amount is usually too low to meet a gecko’s needs.
This is why it’s recommended to give feeder insects a calcium supplement prior to feeding.
Preventing Metabolic Bone Disease
Metabolic bone disease (MBD) is a serious condition caused by inadequate calcium levels. MBD causes a range of bone abnormalities and disabilities in leopard geckos. Here are some ways that optimal calcium intake helps prevent MBD:
- Getting enough calcium prevents the body from needing to leach calcium from the bones. This maintains bone integrity.
- Adequate dietary calcium also allows proper vitamin D3 utilization and absorption of calcium in the digestive tract.
- Sufficient calcium inhibits excess parathyroid hormone production, which causes the body to break down its own bone.
- Meeting calcium needs through supplements prevents the need to rely solely on internal calcium stores.
Leopard geckos with MBD may exhibit bumpy joints, soft jaws, rubbery legs, paralysis, and other deformities. But with proper calcium and vitamin D3 supplementation, these abnormalities can often be reversed, especially when caught early.
Providing adequate calcium is key to keeping geckos healthy and active.
Age | Calcium Recommendation |
---|---|
Hatchlings under 1 year | Calcium 3-5 times weekly |
Juveniles 1-2 years | Calcium 2-3 times weekly |
Adults over 2 years | Calcium 1-2 times weekly |
Most experts recommend dusting feeder insects with a pure calcium supplement free of phosphorus and vitamin D3 several times per week. The exact frequency depends on the gecko’s age (see table). Adults may only need it once or twice weekly.

The Role of Vitamin D for Calcium Absorption
Allowing Calcium Uptake from the Gut
Vitamin D plays a vital role in enabling leopard geckos to absorb calcium from their diet. It promotes calcium uptake in the small intestine by influencing the cells lining the gut to express a calcium-binding protein.
This protein, known as calbindin, ferries calcium from the intestinal lumen into blood vessels underneath. So in essence, vitamin D flicks the “on switch” to activate calcium absorption.
Without sufficient vitamin D levels, gut cells cannot properly synthesize calbindin. The calcium transport chain breaks down, preventing adequate uptake from occurring even when excess calcium is present in the gut. Blood calcium levels then plummet over time, leading to hypocalcaemia.
Regulating Calcium Levels in the Body
On top of its role in the intestines, vitamin D also regulates calcium homeostasis throughout the body. It works in tandem with parathyroid hormone (PTH) to tightly control blood calcium within a narrow optimal range.
When serum calcium drops too low, vitamin D production is ramped up under influence from PTH. This promptly restores calcium absorption efficiency to bring levels back up.
Conversely, elevated calcium triggers reduced vitamin D activation to prevent toxicity. This feedback loop maintains balance, ensuring a constant supply of calcium for essential bodily functions like bone mineralization and muscle contraction.
Without this regulatory axis, uncontrolled fluctuations in blood calcium can occur in leopard geckos. Abnormally high levels lead to lethal calcification of soft tissues, while chronically low concentrations cause poor bone health and metabolic bone disease.
Calcium Powder Guidelines and Frequency
With D3 Calcium Recommendations
Calcium powders containing vitamin D3 are essential for providing optimal calcium absorption and preventing metabolic bone disease in leopard geckos. Here are some key recommendations when using D3 calcium:
- Use a calcium powder that contains calcium carbonate as the calcium source along with vitamin D3. Popular brands like Repashy and Zoo Med Repti Calcium contain both.
- Dust prey items with D3 calcium 3 times per week for juvenile leopard geckos under 1 year old. This provides crucial support for bone growth and development.
- For adult leopard geckos over 1 year old, use D3 calcium once or twice per week. The frequency depends on the individual gecko’s health status.
- Use only a light dusting that slightly coats the prey item. Excessive D3 can cause toxicity.
- After a couple months on a D3 schedule, it’s a good idea to get a check up to ensure proper bone health and look for early signs of metabolic bone disease.
By following these D3 calcium guidelines, leopard gecko owners can promote strong bones, prevent bone deformities, and support their pet’s optimal well-being.
Without D3 Calcium Recommendations
Calcium without vitamin D3 also plays an important role in a leopard gecko’s nutritional regimen. Here are some tips on using plain calcium:
- Use a plain calcium carbonate powder without vitamin D3 added. Reptile brands like Zoo Med and Fluker’s offer these products.
- Feed plain calcium much more frequently than D3 calcium – 4-5 feedings per week is a good target.
- This provides a steady calcium source to balance out the phosphorus levels from feeder insects.
- Excess plain calcium is not toxic, so geckos can lick it directly from a dish in their tank at any time.
- Plain calcium is crucial for egg-laying female leopard geckos to help form healthy eggshells.
- Use plain calcium alongside D3 on feedings when extra calcium is needed, such as after egg-laying.
In combination with proper D3 supplementation, offering regular access to plain calcium gives leopard geckos the optimal calcium intake their bodies need.
Tips for Picking the Best Leopard Gecko Calcium Powders
Calcium to Phosphorus Ratios
When selecting a calcium supplement for your leopard gecko, it’s crucial to pay attention to the calcium to phosphorus ratio. The optimal ratio is around 2:1 – that means there should be about twice as much calcium as phosphorus in the powder.
Too much phosphorus can inhibit calcium absorption and lead to metabolic bone disease. On the flip side, too little phosphorus isn’t good either as both are needed for proper bone growth and maintenance.
Some great calcium powders like Repashy’s Calcium Plus have a calcium to phosphorus ratio very close to the ideal 2:1. Checking the guaranteed analysis on the label will tell you the exact amounts.
Additional Ingredients to Support Bone Health
In addition to calcium and phosphorus levels, pay attention to other bone-beneficial ingredients like vitamin D3, magnesium and manganese.
Vitamin D3 aids with calcium absorption and bone mineralization. Many experts recommend using a calcium powder with D3 no more than 1-2 times a week, as too much can cause vitamin toxicity.
Magnesium plays a vital role in bone formation and manganese is involved in bone metabolism. Including some magnesium and manganese along with balanced calcium and phosphorus is the ideal combo.
Some top calcium supplements like Repti Calcium with D3 contain added magnesium, vitamin D3, and manganese for maximum support.
Powder Texture and Taste
When dusting feeder insects, the texture and taste of the powder matters too. Finely ground powders stick better to insects and are more palatable to geckos.
Avoid powder clumps and go for a smooth, ultra-fine powder that insects can walk through. This leads to better supplementation each feeding.
Taste is something to consider too. While we can’t ask leopard geckos how something tastes, it’s best to go with a reputable powder brand that geckos seem to like.
Watch to see if your leopard gecko eagerly licks powder off feeders vs hardly touching dusted insects. This can give you an idea of which calcium powder has the best taste and appeal.
Signs of Calcium or Vitamin D3 Deficiency
Twitching and Muscle Spasms
Lack of calcium can lead to muscle twitching, spasms, and tremors in leopard geckos. This happens because calcium is essential for proper muscle contraction and nerve functioning. Without adequate calcium levels, the gecko may experience random muscle twitches, spasms in the legs, tail, or jaw, and overall shakiness.
Additionally, geckos deficient in vitamin D3 may show similar symptoms since D3 aids in calcium absorption. If the twitching and tremors persist, it likely signals a major calcium deficiency issue.
Bent Legs and Bone Deformities
Another clear sign of calcium deficiency is bent or deformed legs and bones. Calcium is crucial for proper bone formation and strength. Low levels can cause a condition called metabolic bone disease (MBD) where the bones become soft, weak, and malformed.
Geckos with MBD often have bent femurs and tibias, causing the back legs to be splayed out instead of tucked under the body. The front legs may also bend at odd angles. In severe MBD cases, the jaw and spine curve abnormally too.
MBD can be very painful and debilitating if not treated promptly with calcium supplements.
Changes in Appetite and Activity Levels
Lack of calcium and vitamin D3 may cause changes in a leopard gecko’s appetite and activity levels. A gecko getting insufficient calcium often loses interest in food and has a poor appetite. Loss of appetite results from the nutrients deficiency making the gecko feel unwell.
Lethargy and inactivity can also occur when calcium levels drop. The gecko will seem weak, move less, and sleep more than usual. Again, this relates back to the importance of calcium for muscle and nerve function. Without enough calcium, the gecko lacks energy and motivation to move around normally.
Appetite and activity levels should return to normal after restoring adequate calcium and D3 intake.
Conclusion
Providing the right calcium supplements, both with and without D3, is crucial for leopard geckos. By following the dosing guidelines outlined and choosing a high quality powder, you can support strong bones and prevent metabolic bone disease.
With the information in this guide, you now have everything you need to pick the perfect calcium for your leopard gecko and keep them healthy long-term.
