What it is

Flax oil, also known as linseed oil, is a vegetable oil extracted from the seeds of the flax plant (Linum usitatissimum). The seeds are typically pressed to extract the oil, which is then often refined. It is a source of alpha-linolenic acid (ALA), an omega-3 fatty acid.

Why it's used

Flax oil is used as a dietary supplement and as an ingredient in foods like salad dressings, mayonnaise, and yogurt. It is added for its nutritional profile, particularly its omega-3 content. It can also act as a source of healthy fats in various food products.

Health notes

Flax oil is generally recognized as safe (GRAS) by the FDA for use in food. It is a source of ALA, an essential fatty acid. Some studies suggest potential benefits for heart health, but research is ongoing and evidence is mixed. JECFA has evaluated flaxseed oil and established an acceptable daily intake.
