Why Cod Liver Oil Is Different from Regular Fish Oil

Omega-3 supplements are widely available today, but not all Omega-3 products are the same. Two commonly confused products are cod liver oil and fish oil. While both provide Omega-3 fatty acids, they differ significantly in their origin and nutritional profile.

1. Source of the Oil

Fish oil is typically extracted from the flesh of oily fish, such as anchovies, sardines, or mackerel.

Cod liver oil, however, is extracted from the liver of cod fish, traditionally harvested from the cold waters of the North Atlantic.

This difference in origin leads to important nutritional distinctions.

2. Natural Vitamins
