What Are the Best Calcium Supplements for Leopard Geckos?

If you’ve ever wondered whether your leopard gecko is getting enough calcium, you’re not alone. Proper calcium supplementation is one of the most important aspects of gecko care. Without it, they risk developing serious health problems like Metabolic Bone Disease (MBD). But which calcium supplements are best, and how do you use them? Let’s dive in.

Why Calcium is Essential for Leopard Geckos

Calcium isn’t just a nice-to-have—it’s a must. Leopard geckos need calcium to build strong bones, support muscle function, and prevent MBD, a condition that weakens their skeletal system and can cause deformities.

While feeder insects like crickets and mealworms are great for protein, they’re notoriously low in calcium. That’s why supplementation is so critical. It bridges the nutritional gap and ensures your gecko stays healthy.

Types of Calcium Supplements

Not all calcium supplements are the same, and choosing the right one depends on your gecko’s environment. Here are the three main types:

1. Plain Calcium Powder (Without Vitamin D3)
   This type is ideal for geckos in enclosures with UVB lighting, as UVB helps them naturally produce vitamin D3.
2. Calcium With Vitamin D3
   If your gecko doesn’t have UVB lighting, this type is essential. It provides the D3 they need to absorb calcium properly.
3. Multivitamin Blends
   These all-in-one powders combine calcium, D3, and other vitamins. They’re convenient but should be used sparingly to avoid overdosing on vitamins.

Here are some of the most recommended options:

• Zoo Med Repti Calcium Without D3

• Fluker’s Repta Calcium With D3
  A reliable choice for setups without UVB lighting, ensuring your gecko gets both calcium and D3.
• Repashy Calcium Plus
  A favourite among reptile owners, this all-in-one blend includes calcium, D3, and other essential nutrients.

How to Use Calcium Supplements

Supplementing calcium doesn’t have to be complicated. Here’s how to do it effectively:

• Dust the Feeder Insects
  Place your feeder insects in a small container, add a pinch of calcium powder, and shake gently to coat them evenly.
• Provide a Calcium Dish
  Some geckos will lick calcium when they need it. Place a shallow dish of plain calcium powder (without D3) in their enclosure.
• Follow a Supplementation Schedule
  Use plain calcium for most feedings, calcium with D3 twice a week, and multivitamins once a week. This balance ensures they get what they need without overdoing it.

Common Mistakes to Avoid

Even experienced gecko owners make mistakes. Here’s what to watch out for:

• Overloading on Vitamin D3
  Too much D3 can harm your gecko. Stick to a regular schedule and follow the product’s instructions.
• Skipping UVB Lighting Without D3 Supplements
  If you’re not using D3 supplements, UVB lighting is critical for helping your gecko absorb calcium. Learn more in our post on Do Leopard Geckos Need UV Light?.
• Using Expired Products
  Supplements lose potency over time. Always check expiration dates and replace old powders as needed.

Choosing the Right Supplement

The best calcium supplement depends on your gecko’s setup. If you use UVB lighting, stick to plain calcium powder. No UVB? Go for a supplement with D3. And if you prefer simplicity, an all-in-one like Repashy Calcium Plus is a great choice.
