What it is

Flax seed oil is extracted from the seeds of the flax plant (Linum usitatissimum). The seeds are typically pressed or solvent-extracted to yield the oil, which is then often refined. It is a source of alpha-linolenic acid (ALA), a plant-based omega-3 fatty acid.

Why it's used

Flax seed oil is used as a dietary supplement and as an ingredient in foods like salad dressings, sauces, and baked goods. Manufacturers may add it to boost the omega-3 content of products. It is also found in some energy bars and snack foods.

Health notes

Flax seed oil is generally recognized as safe (GRAS) by the FDA when used as a food ingredient. It is a source of ALA, which the body can convert into EPA and DHA, though this conversion is inefficient. Some research suggests potential benefits for heart health and inflammation, but evidence is mixed and more studies are needed. JECFA has evaluated flax seed and flax seed oil and established specifications for their identity and quality.

Allergen info

Flax seed is not one of the FDA's 9 major allergens. It does not contain gluten.
