Flax oil is pressed from flax seeds. Food-grade oil is cold pressed and typically sold refrigerated to maintain stability of its high omega-3 fatty acid content.

Health considerations

Fatty acid profile varies naturally, but flax oil is predominantly composed of polyunsaturated fatty acids, with the majority of these being the omega-3 fatty acid alpha-linolenic acid. Flax oil supplementation has been found to increase circulating and tissue levels of fatty acids with benefits for heart health. See: Flax; Alpha-linolenic acid; Omega-3 fatty acids

Keep in mind

As flax oil is used in a variety of industries including as a pigment binder in oil painting, it is important to buy food-grade flax oil. High heat cooking and even storage in direct light or at room temperature may compromise the fatty acid profile of flax oil.
