Omega 3 fatty acids are also called n-3 fatty acids or ω-3 fatty acids, are polyunsaturated fatty acids (PUFAs) along with dual bond (C=C) at the third carbon atom from the end of the carbon chain. Omega 3 products are vital fatty acids since the human body is not capable of producing them on its own. Therefore, humans have to rely on omega 3 food and supplements in the diet to supply these extremely beneficial compounds. One of the key significance of omega 3 products is the fact that it has an anti-inflammatory effect. There are three different types of omega 3 PUFA which are involved in human physiology - docosahexaenoic acid (DHA) (both commonly found in marine oils), eicosapentaenoic acid (EPA), and α-linolenic acid (ALA) (found in plant oils). This compound is one of the most key nutrients of regular diets and is essential for toughening and strengthening the immune system, relating the blood pressure, and healthy brain development. The preferred sources are EPA and DHA, and both of these sources are found in abundance in seafood like sardines and salmon. Whereas, ALA is found in plants as well as nuts and seed, and superior quality cuts of meat like grass-fed beef. Omega 3 has its abundance in marine oils, and is also sourced from algal oil, cod liver oil, flaxseed oil, and other fish oils. Most of these oils are used in several dietary supplements, pharmaceuticals and animal feeds, and functional foods and beverages. A recent analysis based on omega 3 products market states that across the world more population is getting widely aware of the omega 3 benefits and incorporating it in their day-to-day healthy lifestyle.
