What is Cod Liver Oil?

Cod liver oil, often referred to as "liquid gold," is derived from the livers of cod fish, primarily from species such as Gadus morhua. This oil is not only a culinary delicacy in some cultures, where fresh cod liver is enjoyed for its unique flavour and texture, but it also serves as a convenient dietary supplement for those looking to enhance their health. 

A 2007 study issued in the journal Agricultural and Biological Sciences, reveals the composition of cod liver is 32 per cent moisture, 55.1 per cent healthy fat, 4.6 per cent protein, and 3.6 per cent ash. These fats include a balanced mix of monounsaturated, saturated, and polyunsaturated fatty acids, which are crucial for various bodily functions. Among these, omega-3 fatty acids, which are particularly abundant in cod liver oil, play a vital role in supporting heart health, reducing inflammation, and promoting brain function.

4. Enhances skin and eye health: Vitamin A supports vision and prevents issues like night blindness, while omega-3s and vitamin D improve skin hydration and elasticity, aiding conditions like eczema.
5. Promotes brain function: Omega-3s are vital for brain health, supporting memory, mood regulation, and overall cognitive function.
