Niacin (vitamin B3) supports energy metabolism, digestive health, and nervous system function in your budgie. It is involved in over 400 enzymatic reactions in the body, more than any other vitamin-derived coenzyme. Niacin helps maintain healthy skin and mucous membranes (including the crop and digestive lining) and supports proper circulation. Seeds and grains provide moderate niacin levels for budgies.
A teaspoon of sunflower seeds provides roughly 0.2mg of niacin — your budgie's feed should contain approximately 30-60 mg of niacin per kilogram, which translates to roughly 0.1-0.4mg per day. A varied seed mix with occasional vegetables meets niacin needs comfortably.
0.02% of daily nutrient intake
Vitamin B3 (Niacin) makes up 0.02% of your budgerigar's total daily nutritional requirements by weight. That's a tiny amount — but it matters.
Inflamed tongue and mouth (black tongue disease in severe cases), poor feather condition, digestive problems including diarrhea, leg weakness, reduced appetite, and general failure to thrive.
Niacin excess from food sources is extremely rare and well tolerated. Water-soluble B vitamins are readily excreted.
