Which Vitamins Are Essential for Your Birds?

If you have birds as pets then you would know they require different care to cats and dogs. It’s essential that you have all the necessary items to ensure they have a healthy, happy life from food and vitamins to safe bird toys, along with lots of attention. Depending on the type of pet bird you have, they can be low-maintenance animals when you keep a close eye on them but underlying issues, such as a vitamin deficiency, commonly go unnoticed.

Malnutrition is one of the most common problems vets encounter with birds. Owners not giving the right kind of food that provide essential vitamins and minerals for birds, along with picky eaters, often are all contributing factors.

Pet birds typically have a seed-based diet and, although these seeds can be rich in oil and carbohydrates, they’re mostly low in protein, minerals, vitamins, and essential amino acids. It is important owners closely watch their birds’ diet and add essential nutrition where it is lacking through a balanced diet curated with their trusted vet.

Common Vitamin Deficiencies in Pet Birds

When it comes to essential vitamins for birds, deficiencies are not uncommon. They also often have significant health effects on your bird.

Vitamin A

A Vitamin A deficiency often goes unnoticed, but it is the most common deficiency pet birds have. Birds that mostly have a seed-based or nut-based diet often lack a variety of vitamins, not just vitamin A and are more prone to this problem.

Vitamin A is important for growth, hormone production, a healthy immune system, and the healthy formation of vascular and mucous membranes. It is also important for good vision and healthy pigment of birds, especially parrots. Some bird species, such as lorikeets, may, however, need less Vitamin A in their diet to avoid iron storage disease.

This deficiency affects respiratory, digestive, and reproductive systems. You may notice signs like anorexia, difficulty breathing, nasal discharge, nasal cavities, swollen eyes, plaque, and large and infected abscesses leading to suffocation. As a result, your bird may develop chronic health issues or experience more frequent conjunctivitis, pododermatitis and sinusitis.

Vitamin D & Calcium

Just like humans, birds get their Vitamin D from the sun, but this can be an issue if they are always kept inside. Additionally, calcium is tied to Vitamin D as Vitamin D helps birds absorb calcium. These nutrients are needed for muscle functions, bone health, brain activity and egg formation. Imbalances of Vitamin D and calcium can cause metabolic bone disease, hyperthyroidism, and changes in mood.

Vitamins E, B, K, C

Vitamins E, B, K and C are also important for birds. In fact, they are essential for a healthy functioning nervous system, energy production, growth, immune functions, and collagen production.

Amino Acids & Protein

Both amino acids and protein are needed for feather, bone, muscle, enzyme and hormone growth and function. A lack of proteins and amino acids in birds can lead to serious health issues like unhealthy growth and development, which can unfortunately lead to even death.


A seed-based diet usually lacks Iodine, which is essential for maintaining thyroid hormones and healthy thyroid gland function. Iodine deficiency can cause goitres, especially for budgies.

What to Watch Out for: Symptoms of Vitamin Deficiency

Like people, birds may not always show the same symptoms or any at all when they are unwell or lacking a certain nutrient. Therefore, you need to monitor your pet’s behaviour closely and be aware of key symptoms that could indicate vitamin deficiencies.

However, it is important to note that symptoms tend to be easier to spot with birds that are more physically active and vocal since it’s more obvious when you see changes in their behaviour. But the changes can still be subtle.

Regularly look out for signs like:

  • Overall unhealthy appearance
  • Poor feathering
  • Feather discolouration
  • Appearance of cracks and flakes on beak
  • Overgrown toenails and beak
  • Clear discharge or dry crust around nostrils
  • Swelling around eyes
  • Underweight or overweight
  • Changes in stool
  • Feather plucking and picking
  • Low activity, irritability, and moodiness
  • Inability to fly
  • Anorexia
  • Difficulty breathing
  • Constant infections

What Can Happen If You Don’t Act: Complications From Vitamin Deficiencies

Vitamin deficiencies and malnutrition can be easily fixed with the right diet and treatments. However, if it’s spotted too late or ignored, it can lead to more complicated and serious health issues for your pet bird.

Bone Structure & Strength

A healthy bird has a strong bone structure, allowing them to enjoy life. For this though, they need plenty of calcium to maintain their bone health. A lack of calcium in a bird’s diet can not only lead to weak bones but bone diseases, such as metabolic bone disease, and even death.

Poor Feathering

Feathers are one of the main features of a bird that we all admire and notice. They protect birds from various weather conditions, including keeping them warm. Therefore, healthy feathers are essential to your birds overall wellbeing. Changes in feather appearance can be one of the more obvious and easy-to-spot symptoms of a poor diet.

When birds lack certain vitamins it can lead to them picking and plucking at their feathers, as well as discoloration of the feathers. Good feather health requires good nutrients, which includes balanced levels of amino acids, correct calorie intake, fats, vitamins, and minerals.

Respiratory Infections

Poor diet can lead to a weaker immune system causing all sorts of respiratory infections in birds as they find it harder to fight off illnesses. As a result, they may also develop breathing issues. Maintaining a healthy immune system can prevent these infections but also help them fight off any illness more easily when they do get sick.


Overfeeding your pet bird can be quite common — it can be hard to know the right portion size. While we may assume our pets will stop eating when they’re full, it’s not always the case. Similarly, another common mistake amongst owners is feeding birds only seeds. This too can cause obesity. Obesity can be dangerous; it can lead to fatty liver disease, arthritis, and heart disease, when a variety of nutrition isn’t incorporated into their daily feeding routine.

Poor Reproduction

A weak diet can interfere with your bird’s mating habits and can lead to the loss of them being unable to reproduce overall. This often causes lethargy, especially amongst parrots; depression; moodiness and irritability.

Inability to Fly

A malnourished bird often lacks energy and pet owners notice slower or less movement from their birds. Protein is essential to form strong muscles, which are needed for flying. An imbalanced diet often occurs because pet owners think all birds require the same diet, when it often varies between species.

Some eat more or less than their own body weight, others require more of a specific vitamin. It can be hard to find this information yourself, so it’s best to talk to an expert, such as your vet, to be sure you have the right facts.

What Can You Do to Treat & Prevent Vitamin Deficiencies?

Making sure your bird is getting those essential nutrients often comes down to diet and lifestyle. For instance, a diet with kale, sweet potatoes and capsicum can provide the correct levels of Vitamin A.

Similarly, ensuring your bird gets some sunlight, whether through a window without UV protection or time spent safely outside, does wonders for their Vitamin D levels. Where possible, opt for more natural methods rather than supplements as this will be easier for you and your bird to maintain.

Changes you can make include:

  • Incorporating nutritious fresh fruit, vegetables, and nuts into your bird’s regular diet, as well as treats. You may need to experiment with a variety if your bird is a picky eater.
  • Swapping from seeds to a specially formulated pellet diet created for your bird’s species.
  • Feeding your bird balanced portions to avoid overeating. You can also encourage your bird to forage or eat from various locations to get them moving around more and stimulated.
  • Changing the areas where your bird spends most of their time to allow for adequate sunlight.
  • Visiting your vet regularly for check-ups to catch any issues early to allow for the best and most effective treatment. This is also a wonderful time to ask about specific dietary requirements for your bird’s species.

As you make changes to your bird’s diet, ensure that any food you give to them is healthy and safe for them. In general, birds should not be fed chocolate, alcohol, milk products, avocados, apple seeds or caffeinated beverages.

Make Sure Your Bird Has the Best Diet

No pet owner wants their bird to be lacking, whether it’s love and affection or essential nutrients. Look for a pet shop that can provide everything you could need to give your bird the best life possible.
