Centuries ago, northern Europeans used cod liver oil to protect them from the cold. It was made from the livers of Gadus morhua and other species of cod. Cod liver oil was said to relieve such complaints as rheumatism, aching joints, and stiff muscles. It turns out cod liver oil contains large amounts of vitamins A, D, and omega-3 fatty acids, and the health benefits may go beyond rheumatism and rickets. The star ingredient in cod liver oil is omega-3, a polyunsaturated fat. Omega-3 is known as an essential fatty acid because the human body is unable to make it, so itβs necessary to get it from food.
