Cod liver oil is a dietary supplement that is extracted from the liver of Atlantic cod. It is packed with nutrients such as vitamins A and D, as well as omega-3 fatty acids, which are essential for the human body.

Cod liver oil has been used for centuries as a natural remedy for various health conditions due to its numerous benefits, which range from promoting a healthy immune system to reducing inflammation and improving bone health. Some people swear by it for smoother, more radiant skin and shinier hair.
