Does your chameleon have vitamin A deficiency?
Vitamin A deficiency is a common health concern in captive chameleons, especially in species like the Veiled Chameleon (Chamaeleo calyptratus).
Deficiency in this essential nutrient can lead to a variety of health problems, and severe deficiencies can lead to chameleon death if not treated.

What Will I Learn?
The Role of Vitamin A in Chameleon Health
Vitamin A plays a crucial role in various physiological processes for chameleons, just as it does for many other animals. Here are some of its primary functions:
Visual Health
Vitamin A is essential for the health of the retina and contributes to good vision. In chameleons, a deficiency in vitamin A can result in issues like cloudy eyes or even vision loss.
Skin and Mucous Membranes
Vitamin A helps maintain the health of skin and mucous membranes, which can be particularly important for chameleons that shed skin and are prone to skin infections.
Immune System Support
Vitamin A supports the immune system, helping the chameleon fend off infections and diseases.
Reproductive Health
Vitamin A is essential for reproductive health and is particularly important for gravid (pregnant) female chameleons to ensure the healthy development of the eggs.
Respiratory Health
Vitamin A helps to maintain the cells in the lungs and respiratory tract, making it easier for the chameleon to breathe.
Symptoms of Vitamin A Deficiency
Symptoms may include eye problems, lethargy, skin disorders, respiratory issues, or weakened immune function. Severe deficiencies can lead to death if not addressed.
Here are the signs to look for…
Signs of Vitamin A Deficiency in Chameleons
- Eye issues: Swollen or closed eyes, difficulty shedding around the eyes, or a persistent eye infection.
- Respiratory problems: Wheezing, coughing, or other signs of respiratory distress.
- Loss of appetite.
- Skin issues: Poor or incomplete shedding.
- Growth deformities in young chameleons.
Ways to Give Your Chameleon Vitamin A
If you suspect your chameleon is deficient in vitamin A, here are the ways to treat it.
1. Consult a Veterinarian
Consult with a veterinarian who specializes in reptiles (often referred to as a herpetological vet) before administering any supplements or medications. They can provide appropriate dosages and determine the best form of vitamin A for treatment.
2. Give Your Chameleon Supplements
There are two primary forms of vitamin A that can be used for supplementation:
- Preformed Vitamin A (Retinol): This is the animal-based form of vitamin A found in foods like liver. It can be toxic in large amounts, so it’s important not to overdose.
- Provitamin A (Beta-carotene): This is the plant-based form and is converted into retinol in the body as needed. It’s generally considered safer because it’s less likely to cause an overdose.
Commercially available supplements often contain a mix of vitamins and minerals, including vitamin A.
Examples include:
Zoo Med Reptivite: A mix of vitamins and minerals that include vitamin A acetate. Vitamin A acetate falls in the category of “preformed vitamin A” but is less bioactive than retinol. Note that even though it is less bioactive, vitamin A acetate can still pose a risk for toxicity if consumed in large amounts, similar to other preformed types of vitamin A like retinol
Rep-Cal Herptivite: A multivitamin for reptiles. The vitamin A content in Herptivite is from beta carotene, so there is no threat of vitamin A toxicity.
3. Other Dietary Sources
Another method to ensure your chameleon gets adequate vitamin A is by gut-loading feeder insects with foods high in vitamin A or beta-carotene.
This can include:
- Carrots
- Sweet potatoes
- Leafy greens like kale and spinach
4. Injections
In severe cases of vitamin A deficiency, a vet might prescribe vitamin A injections.
Vitamin A Deficiency Prevention
Balanced Diet
Give your chameleon a varied and balanced diet. This often includes gut-loaded insects (like crickets, roaches, and silkworms) and occasional safe fruits and vegetables.
Regular Supplementation
Use a calcium supplement without D3 for almost every feeding and a calcium with D3/vitamin supplement about twice a month or as recommended by a vet.
Regular Vet Check-ups
Regular visits to a veterinarian can help catch potential deficiencies early.
Educate Yourself
The fact that you’re on this page means you’re smart and proactive. Different species of chameleons may have slightly different needs. It’s good to learn the specific requirements of the chameleon species you’re keeping.
While it’s important to ensure that your chameleon receives enough vitamin A, it’s also vital not to over-supplement, as this can lead to a vitamin A overdose…
Vitamin A Overdose Symptoms in Chameleons
Hypervitaminosis A, or vitamin A toxicity, can occur in chameleons if they consume too much of this vitamin through their diet or supplements.
Here’s a list of symptoms your chameleon may experience if it ingests too much vitamin A (Note that the symptoms might not be immediate and could develop over time.)
- Skin Problems Overdosing on vitamin A can lead to skin issues, such as excessive shedding or even lesions.
- Swelling: Particularly around the eyes and mouth, which can be indicative of edema or fluid buildup due to vitamin toxicity.
- Lethargy: Affected chameleons may become sluggish or inactive as a result of toxicity.
- Digestive Issues: Diarrhea, vomiting, or decreased appetite can be symptoms of hypervitaminosis A.
- Neurological Issues: In severe cases, neurological symptoms like seizures or tremors could manifest.
- Bone and Joint Issues: Chronic exposure to excessive vitamin A can result in bone and joint deformities, and in some extreme cases, bone fractures due to weakened structural integrity.
- Respiratory Distress: In extreme cases, high doses can lead to respiratory issues.
- General Poor Health: Weakness, weight loss, and a decrease in growth rate can also be symptoms of vitamin A toxicity.
- Reproductive Issues: Overdose can lead to reproductive problems, which may be difficult to notice unless the chameleon is in a breeding condition.
Treatment and Management
- Immediate Vet Attention: If you suspect that your chameleon has consumed too much vitamin A, consult a vet experienced in reptile care immediately.
- Dietary Review: Under the guidance of a veterinarian, you may need to revise the diet to reduce vitamin A levels.
- Fluid Therapy: In severe cases, the veterinarian might recommend fluid therapy and other treatments to help flush out the excess vitamin A from the system.
- Regular Monitoring: Continued observation and possibly additional tests will be necessary to ensure that the chameleon recovers fully.
Given the potential severity of vitamin A toxicity, prevention is always better than cure. Ensure that the diet and any supplements you provide are well-balanced and appropriate for your chameleon’s species and life stage. Always consult a qualified veterinarian for precise advice tailored to your pet’s needs.
