What it is

Highly refined fish oil is a liquid made from fatty fish like anchovies, sardines, and mackerel. The fish are cooked, pressed to separate oil from solids, and then purified through processes like filtering, bleaching, and deodorizing to remove impurities, odor, and flavor.

Why it's used

It is added to foods as a source of omega-3 fatty acids, specifically EPA and DHA, which are beneficial fats. It is often added to fortified foods like milk, yogurt, and eggs to boost their nutritional value.

Health notes

Highly refined fish oil is generally recognized as safe (GRAS) by the FDA when used as intended. Omega-3 fatty acids are recognized for their role in heart and brain health. JECFA and EFSA have evaluated omega-3 fatty acids. Some people may experience mild side effects like fishy aftertaste or digestive upset.

Allergen info

Fish is one of the 9 FDA major allergens. Highly refined fish oil is derived from fish and is therefore considered a major allergen.
