Cod Liver Oil is among the most concentrated food sources of four nutrients vital to health, which are EPA, DHA, vitamin D, and vitamin A. These nutrients are required for healthy skin and joints, strong bones and teeth, healthy cardiovascular system and nervous system, and prevention of depression and other mood disorders. The main benefit of cod liver oil is linked to its omega-3 content. Omega-3 fatty acids are needed for healthy function of heart, brain, joints, digestive system and many other systems of the body. Another health benefit of the oil is linked to its vitamin E content that assists the body in processing fatty acids and is an essential antioxidant and improves the health of skin and hair.

Vitamin A is a fat-soluble vitamin with known toxicity. Although its toxicity has been exaggerated, it is a factor worth keeping in mind. Carotine is converted in the human body to Vitamin A, it comes from vegetable sources. Vitamin A is necessary for normal growth and for skeletal development.

Vitamin D- The fast soluble vitamin D is perhaps the most underrated nutrient that is produced when sunlight touches the skin. But it is extremely vital for bone health, as without it the body cannot absorb the calcium that you may provide it in the form of supplements. With the advent of beauty products with high sun protection factor, this nutrient is becoming less available to our bodies. Even weaker sunscreens with just SPF-8 prevent the body considerably from producing vitamin D. Diseases such as arthritis, diabetes, certain cancers, multiple sclerosis, and even schizophrenia may stem from deficiency of this vitamin. You can provide vitamin D to your body through supplements and foods like mushrooms, tuna, eggs, dark green leafy vegetables, salmon, sardines, mackerel, fortified dairy products and cereals, yoghurt, and milk.
