Best Biotin-Rich Foods for Backyard Birdss

Ranked by biotin content among foods safe for backyard birdss in the Creature Feast catalog.

Sunflower Seeds per 100g: ~66ug biotin Sunflower seeds contain biotin at approximately 66ug per 100g, making them by far the best feeder source of this B vitamin. Biotin is essential for keratin production and fat metabolism in birds. During molt, biotin demand spikes because the keratinization process that transforms soft feather pulp into rigid, flight-capable feather structure is biotin-dependent. Biotin-deficient birds produce weak, frayed feathers.

Peanuts per 100g: ~34ug biotin Peanuts provide about 34ug of biotin per 100g. Biotin supports the carboxylase enzymes involved in gluconeogenesis and fatty acid synthesis, both critical metabolic pathways for birds that must rapidly build fat reserves before migration or winter. Species that cache peanuts access this biotin supply over extended periods.

Oats per 100g: ~20ug biotin Oats contain about 20ug of biotin per 100g. The biotin in oats is relatively bioavailable and supports the constant feather maintenance that wild birds perform through daily preening. Since biotin is water-soluble and not stored in large quantities, regular intake from diverse food sources helps maintain consistent levels.
