Thiamine (vitamin B1) is essential for your budgie's nervous system function and energy metabolism, helping convert carbohydrates from seeds and grains into usable energy. It plays a critical role in nerve signal transmission and brain health. Budgies with their rapid metabolism and high energy demands need a steady supply of B vitamins. Seeds, especially sunflower seeds and millet, provide reasonable thiamine levels, and a varied diet with grains and legumes ensures adequate intake.
A small pinch of sunflower seeds (about 1g) provides roughly 0.015mg of thiamine — your budgie's feed should contain approximately 2-4 mg of thiamine per kilogram, which translates to roughly 0.01-0.03mg per day. A varied seed mix supplemented with occasional grains and legumes provides adequate thiamine.
0.0% of daily nutrient intake
Vitamin B1 (Thiamine) makes up 0.0% of your budgerigar's total daily nutritional requirements by weight. That's a tiny amount — but it matters.
Neurological symptoms including head tilt (star-gazing or opisthotonos), loss of coordination, seizures, lethargy, reduced appetite, and in severe cases, paralysis. Thiamine deficiency can develop rapidly in small birds because their high metabolic rate depletes B1 stores quickly.
B vitamins are water-soluble and excess is readily excreted in droppings. Thiamine toxicity from food sources is not a practical concern for budgies.
