Cod Liver Oil: Benefits, Uses, and Industry Applications

Introduction to Cod Liver Oil

Cod liver oil is a nutrient-rich dietary supplement extracted from the liver of Atlantic cod (Gadus morhua). Renowned for its high content of omega-3 fatty acids, vitamin A, and vitamin D, cod liver oil has been used for centuries to support overall health, boost immunity, and maintain strong bones. Today, it remains a popular supplement in both consumer and clinical nutrition markets.

What is Cod Liver Oil?

Cod liver oil is obtained by steaming or cold-pressing the liver of cod fish, producing a golden oil that is either consumed as a liquid or encapsulated. Unlike regular fish oil, which is derived from the flesh of various fish, cod liver oil naturally contains high levels of fat-soluble vitamins in addition to essential fatty acids.

Key Health Benefits of Cod Liver Oil

1. Supports Heart Health

Rich in EPA and DHA omega-3 fatty acids, cod liver oil helps lower triglycerides, improve blood vessel function, and reduce the risk of cardiovascular disease.

2. Boosts Immune Function

Vitamin A in cod liver oil strengthens immune defenses by supporting white blood cell production and mucous membrane integrity.

3. Strengthens Bones and Teeth

With its high vitamin D content, cod liver oil promotes calcium absorption, helping prevent osteoporosis and maintaining bone health.

4. Promotes Eye Health

Vitamin A supports vision and may reduce the risk of age-related macular degeneration.

5. Reduces Inflammation

Omega-3 fatty acids in cod liver oil have anti-inflammatory properties that can help manage arthritis, joint pain, and autoimmune conditions.
