Essential Vitamins for Bearded Dragons

A bearded dragon’s diet is vitally important to their health and longevity. Like all living creatures, bearded dragons need a variety of vitamins and minerals to stay healthy. There are a few key vitamins that every bearded dragon owner should be aware of. Understanding what vitamins bearded dragons need and which foods contain those vitamins is crucial for keeping your reptile companion happy and healthy. In this article, we will explore the most important vitamins for bearded dragon.

Vitamin A


Vitamin A is essential for bearded dragons. It plays a crucial role in maintaining healthy eyesight, promoting proper bone development, and supporting a strong immune system. Vitamin A deficiency can cause a host of problems including poor vision, weak bones, and increased susceptibility to infections.

The best sources of vitamin A for bearded dragons are dark leafy greens like kale, dandelion greens, collard greens, and mustard greens. Sweet potatoes and carrots are also packed with beta carotene, which the body converts into vitamin A. Make sure to feed your bearded dragon vegetables like these 2-3 times per week to provide sufficient vitamin A.

Supplementing with a calcium powder that contains vitamin A is also recommended. Repashy’s Calcium Plus is a good all-in-one supplement that provides vitamin A, along with calcium and other key nutrients. Dust insects with this supplement 1-2 times per week to round out your bearded dragon’s vitamin A needs.

Vitamin D3

Vitamin D3, also known as the “sunshine vitamin,” is another essential nutrient for bearded dragons. Vitamin D3 allows the body to properly absorb and utilize calcium. It also promotes bone growth and development.

Since bearded dragons are cold-blooded reptiles, they rely on UVB light for synthesis of vitamin D3 rather than direct sunlight like humans. Make sure your bearded dragon habitat has a linear UVB light bulb so they can activate vitamin D3. Coil-type compact fluorescents bulbs do not produce UVB rays and should be avoided.

You can also provide vitamin D3 by gut-loading insects with supplements before feeding them to your bearded dragon. Dusting insects directly with D3 supplements is recommended too. Repashy’s Calcium Plus contains vitamin D3 for balanced supplementation.

Vitamin B Complex

The family of B vitamins are all important for bearded dragons. Vitamin B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6, B7 (biotin), and B12 are all essential for energy production, eye health, immune function, growth, and development.

Leafy greens, vegetables, fruits, and insects all naturally provide B vitamins. Supplementing with a multivitamin containing B vitamins is recommended too. Herptivite by Repashy contains a full spectrum of vitamins including vitamin B for comprehensive vitamin support.

Vitamin E

Vitamin E functions as an antioxidant in the body. It helps neutralize harmful free radicals and prevent cell damage. Vitamin E also supports a healthy immune system in bearded dragons.

Good natural sources of vitamin E include leafy greens like kale, dandelion greens, collard greens, parsley, and basil. You can also find vitamin E supplements to help meet your bearded dragon’s needs.


In additional to vitamins, bearded dragons also need a variety of minerals to stay healthy. Calcium and phosphorus are crucial for bone health. Magnesium supports enzyme function and muscle health. Sodium, chloride, potassium, iron, zinc, manganese, copper, iodine, and selenium are all important too.

Feeding a varied diet of greens, vegetables, fruits, and insects will provide a range of vitamins. Using supplements like Repashy Calcium Plus and Herptivite will help fill any nutritional gaps.


Ensuring your bearded dragon receives the right balance of vitamins is one of the most important aspects of care. Vitamins like A, D3, B complex, and E all serve vital roles in your bearded dragon’s health and wellbeing. Feed a diverse diet, provide proper lighting, and use supplements to cover all your bearded dragon’s vitamin needs. With the right vitamin sources, your beardie will thrive for years to come!
