Cod liver Oil: Health benefits, Uses & Dosage

 

What is COD liver oil?

The liver of the Gadus Morhua fish is used to make cod liver oil. Cod liver oil can be absorbed by the consumption of raw cod liver or through supplementation. It includes reasonably high concentrations of vitamin A and vitamin D and is one of the greatest sources of omega 3 fatty acids (EPA and DHA).

It is one of the most extensively used fish oil supplements, with individuals of all ages taking it for its numerous health advantages.

Some "fatty acids" found in cod liver oil prevent blood from clotting quickly. These fatty acids also help to alleviate inflammation and discomfort. There is no good strong evidence to prove the use of cod liver oil for heart health, depression, arthritis, and a variety of other illnesses.

The oil taken from the livers of Atlantic cod is known as cod liver oil. It is often used as a dietary supplement and is high in nutrients.

A teaspoon of cod liver oil provides approximately 40 calories, 4500 IU vitamin A, 450 IU vitamin D, and 888 mg omega-3 fatty acids. This amounts to almost 90% of the daily intake for vitamin A and 113% of the daily value for vitamin D.

  •  acid (EPA) is an omega-3 fatty acid that works in conjunction with DHA, and the two are frequently mentioned together. Eicosapentaenoic acid helps the heart and is an essential vitamin for reducing inflammation and improving mood.
  • Vitamin A is a fat-soluble vitamin that helps your body accomplish numerous critical processes. Supporting eyesight and immune system function and cellular and reproductive health are among its most significant functions. It's also an excellent antioxidant.
  • Vitamin D is a fat-soluble vitamin that is important for bone health. Vitamin D insufficiency has been related to bone problems like rickets, but also depression as well as poor heart and metabolic health, autoimmune disease, and even cancer.
