Flax seed oil is a rich source of the essential fatty acid alpha-linolenic acid (ALA), which is thought to convert to the omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). The benefits of omega-3 fatty acids for horses are to reduce body-wide inflammation and to support immune function with specific applications for allergies, skin conditions, respiratory issues, and joint health.
