Whether you're exploring it for the first time or returning to it as a trusted staple, cod liver oil remains a valuable part of a balanced health routine.

What Is Cod Liver Oil?

Cod liver oil is extracted from the liver of cod fish (typically Atlantic or Arctic cod). Unlike regular fish oil, which is derived from the fatty tissues of various fish, cod liver oil naturally contains higher concentrations of vitamins A and D, making it both a nutritional supplement and a therapeutic oil.

Key Nutrients in Cod Liver Oil

• EPA (Eicosapentaenoic Acid) – An omega-3 fatty acid that supports heart health, reduces inflammation, and promotes mood balance.

• DHA (Docosahexaenoic Acid) – An omega-3 that plays a crucial role in brain function, cognitive development, and eye health.

• Vitamin A – A fat-soluble vitamin essential for vision, immune health, and skin integrity.

• Vitamin D – Supports calcium absorption, bone health, immune function, and hormonal balance especially important in northern climates with limited sun exposure.

Health Benefits of Cod Liver Oil

1. Heart Health Support

The omega-3s in cod liver oil help reduce triglycerides, lower blood pressure, and support healthy cholesterol levels, all of which contribute to a lower risk of cardiovascular disease.

2. Brain and Mood Enhancement

DHA is critical for cognitive performance, memory, and focus. EPA may also support a balanced mood and reduce symptoms of mild anxiety or depression especially when combined with adequate vitamin D.

3. Stronger Bones and Joint Support

Thanks to its vitamin D content, cod liver oil helps with calcium absorption, supporting bone density and reducing the risk of osteoporosis. It also provides anti-inflammatory benefits for joints, potentially easing stiffness and discomfort.

4. Immune System Boost

The combination of vitamin A and vitamin D makes cod liver oil a natural immune enhancer, helping the body defend against infections and maintain balanced immune responses.

5. Eye and Skin Health

Vitamin A is essential for retinal function and may help protect vision, especially in low-light conditions. The nutrients in cod liver oil also support skin elasticity, hydration, and may reduce inflammation in skin conditions like eczema.

• Adults looking to support heart and brain health

• Children needing cognitive and immune support

• Seniors aiming to preserve bone strength and mobility
