Vitamins are organic compounds that are vital for regulating bodily functions and supporting overall health. Leopard geckos, like other reptiles, require a variety of key vitamins in their diet. When kept as pets, their vitamin needs must be met through proper supplementation as they do not produce certain vitamins naturally.

Some of the benefits of providing the right vitamins include:

  • Strengthening bones and preventing metabolic bone disease. Metabolic bone disease is a common problem in captive reptiles caused by deficiencies in calcium and vitamin D3.
  • Supporting a healthy immune system and ability to fight off infections. Vitamins A, C, and E all help boost immune function.
  • Promoting proper growth, appetite, and weight gain. B vitamins especially support a healthy metabolism.
  • Ensuring good vision, skin, and muscle function. Vitamins A and E contribute to eye, skin, and muscle health.
  • Increasing energy levels and activity. The B complex vitamins help maintain energy production.

Without proper supplementation, leopard geckos are at risk for developing vitamin deficiencies that negatively impact their health. Providing a varied diet along with vitamin supplements helps prevent this.

Key Vitamins for Leopard Geckos

There are several important vitamins to make sure to supplement for leopard geckos. These include:

Vitamin A

Vitamin A supports skin health, vision, and bodily functions. Signs of deficiency include eye problems, mouth inflammation, and poor skin regeneration. Vitamin A also helps strengthen the immune system. Good sources include liver, carrots, sweet potatoes, dandelion greens, and supplements.

Vitamin D3

Vitamin D3 aids in calcium absorption and bone formation. Without it, leopard geckos are prone to metabolic bone disease. Natural D3 is obtained from UVB exposure, but supplements are needed for geckos without regular UV light.

Vitamin E

This vitamin protects cells and acts as an antioxidant. It contributes to healthy skin, eyes, muscles, and overall wellbeing. Plant oils, nuts, seeds, liver, and supplements provide vitamin E.


Calcium is crucial for strong bones and preventing metabolic bone disease. It is also key for muscle contraction, nerve function, and enzyme regulation. Calcium must be provided with vitamin D3 for proper absorption.

Vitamin B complex

The B vitamins aid metabolism, energy production, appetite, and digestion. Includes thiamine, riboflavin, niacin, B6, B12, biotin, folate, and pantothenic acid. Found in whole grains, meats, eggs, and vegetables.

Vitamin C

Vitamin C boosts immunity and acts as an antioxidant. Helpful but not essential since geckos can produce some vitamin C naturally. Offering veggies high in C provides added benefits.

Providing Vitamin Supplements

The ideal way to provide vitamins is through a varied diet of insects, calcium-rich foods, and veggies. However, supplements are needed to ensure adequate intake of key vitamins and minerals.

The most important vitamin supplements for leopard geckos are calcium with D3 and a general multivitamin. Using a supplemental powder makes it easy to lightly coat insects and mix into food 2-3 times per week. This guarantees your gecko gets all the vitamins they need.

Calcium with D3 is crucial for metabolic bone health. Alternate between calcium and a multivitamin so your gecko does not overdose on calcium. General multivitamins provide an array of vitamins including A, E, B complex, and sometimes C.

Meal replacement powders can also provide balanced nutrition all-in-one but should not fully replace whole foods. Always follow supplement directions and consult your vet on proper usage.

For optimal absorption, use supplements made for reptiles and keep them refrigerated after opening. Also make sure your UVB and heating is setup properly as some vitamins require specific conditions to be usable.


Ensuring your leopard gecko gets all the vitamins they need is an important part of caring for them. Key vitamins like A, D3, E, B complex, calcium, and vitamin C all provide vital health benefits ranging from bone support to boosting immunity. Through a diverse diet and proper supplementation 2-3 times per week” you can supply your gecko with the nutrition they need to be happy and healthy. Consulting your vet on the ideal supplements and servings for your pet is recommended. With the right balance of whole foods and vitamins, your leopard gecko will continue to thrive.
