www.MyHealthySupplement.comWhy are omega- 3 fatty acids called essential fatty acids (EFA)? The omega-3 group of fatty acids are called Essential Fatty Acids (EFA) simply because they are needed for a number of important physiological purposes and we do not have them in our bodies. They are essential for our body yet our body cannot make them on its own. They have to be derived from seafood and plant food sources in our diet. These fatty acids can be found in marine life such as algae, salmon, tuna and cod. Certain plants and vegetables such as flax seed oil contain omega-3.The daily recommended allowance is to have seafood at least twice a week and to choose salt water fish. The smelly fish such as mackerel, sardines, kippers, anchovies and trout tend to be higher in omega-3 fatty acids. It is important to choose fish that are not contaminated with heavy metals such as lead and mercury. This is increasingly difficult or near impossible as nearly all our water ways and oceans are contaminated with these metals.As seafood maybe expensive or difficult to get depending upon your geographical or financial situation so turning to fish oil in a capsule is the next most affordable and convenient way for most individuals. The other reason is that we can be almost sure that the fish oil in a capsule is free of contamination of heavy metals. This is where you must be prepared to take a look at the integrity of the company manufacturing the capsule as well as the manufacturing process put in place for the production of supplements and specially fish oil capsules.
