Pantothenic acid (vitamin B5) is a building block of coenzyme A (CoA), one of the most important molecules in metabolism. CoA sits at the crossroads of energy production — it is required for breaking down carbohydrates, fats, and proteins into usable energy, and for synthesizing fatty acids, steroid hormones, and hemoglobin. For your budgie, this translates to steady energy for flight, active foraging, and the constant vocal activity that budgies are famous for.
Pantothenic acid also supports the adrenal glands, which produce hormones that help your budgie cope with stress — whether from a cage move, a new companion, handling, or illness. Adequate B5 helps maintain a balanced stress response rather than an overreaction.
For feather growth specifically, pantothenic acid is involved in keratin production and the formation of healthy feather structure. During the annual molt, when your budgie replaces every feather on its body over several weeks, the demand for B5-dependent metabolic pathways increases substantially. Seeds and grains provide reasonable B5 levels, and cooked egg yolk is an excellent concentrated source.
A small amount of cooked egg yolk (about 2-3g) provides roughly 0.03-0.05mg of pantothenic acid — your budgie's feed should contain approximately 10-20 mg of pantothenic acid per kilogram, which translates to roughly 0.04-0.12mg per day from their 4-8g food intake. A varied diet of seeds, egg, and fresh vegetables comfortably meets B5 requirements.
0.0% of daily nutrient intake
Vitamin B5 (Pantothenic Acid) makes up 0.0% of your budgerigar's total daily nutritional requirements by weight. That's a tiny amount — but it matters.
Dermatitis on the feet and around the beak, poor feather quality (rough or brittle feathers), reduced growth in chicks, reduced egg hatchability, lethargy, irritability, and impaired stress tolerance. True clinical deficiency is uncommon because pantothenic acid is widely distributed in foods.
Pantothenic acid is water-soluble and excess is readily excreted. Toxicity from dietary sources has not been reported in birds. Even supplemental doses well above normal intake appear safe.
