GNC flax seed oil capsules are made with unrefined cold pressed flax seed oil for maximum potency and purity. Flaxseed oil contains both omega-3 and omega-6 fatty acids, which are needed for health. It is a good source of essential Omega 3, alpha-linolenic acid (ALA), which the body converts into Eicosapentaenoic acid (EPA), and Docosahexaenoic acid (DHA), the omega-3 fatty acids found in fish oil.
