In studies of parrots, Omega 3 fatty acids were associated with a reduced incidence of atheriosclerosis. In another interesting study, the hatchlings of parents fed flax oil were found to have higher levels of antibody production.

Only premium Northern-grown flax seed is used for AviFlax. Flax seed is not usable whole and must be ground to release beneficial fatty acids. If ground too aggressively, nutrients can be lost due to oxidation and other damage, so AviFlax is gently milled to retain maximum nutritional benefit. While flax oil contains Omega 3, whole milled seed is better for birds as it provides the fiber, antioxidants, lignans and proteins missing from oil in an easy to feed form.
