EFAs are those necessary fats that we as humans are unable to synthesize in our bodies and must be obtained from either diet or supplementation. Just like essential amino acids (EAAs as found in Animal Nitro), and other essential micronutrients such as vitamins and minerals, we need optimum amounts in order for the body to function properly, let alone to make gains in lean mass. These essential omga 3 fats are needed for normal growth and development in children and for proper heart function. Getting the proper EFAs isn't always easy, especially when they can only be obtained from certain foods. A typical diet consists of an overabundance of saturated fats, trans fats, and those fats from plant sources (think of common cooking oils) usually containing large concentrations of omega 6 compounds, as they are the easiest and most economical to get your hands on. Omega 6s are important, as they are EFAs too. But it's not just the types of fats. It's also the ratios. More on that later. For supplementation purposes there are only 2 types of fats that are needed; Omega 3's (n-3) and Omega 6's (n-6). Omega 9 is necessary, yet not essential because it can be made by the body in modest amounts. The reason why the body can't make an n-3 or n-6 fatty acid is that human metabolism can't add a double bond to a fatty acid that is more than 9 carbons away from the delta end (acid end). This is also the reason why the body can't convert an n-3 fatty acid to an n-6 fatty acid. Yeah, it sounds like science mumbo jumbo, but is important to see from a chemistry perspective why it's so hard to obtain the right EFAs from the diet. This is where a supplement like Animal Omega comes into play. Sure, it ain't fancy. No cool bells and whistles here, just the basics. It's not going to "pack on 10 lb in a week" but long-term, it'll get ya to where ya want to be. EFAs are needed, not just any old EFAs, but the right kinds and the right amounts. That's what Animal Omega is all about. Omega may be the most complete EFA product on the market. It contains the right fats that bodybuilders require. It's a full spectrum, molecularly distilled EFA supplement, each pack containing a precise and pre-dosed ratio of n-3 to n-6. It is packed with sources of Omega 3 oils extracted from various fish sources such as salmon, cod liver, herring, and plant-sourced omega 3s from flaxseed oil. Such a well-rounded mixture, ensures that you obtain all of the various n-3 extracts that are so important for general health. You get the balance of alpha linoleic acid from flax and the key fish oil extracts, EPA and DHA. Another important aspect of this complex is the addition of important antioxidants, Vitamins A, D and E, which ensure EFA stability and prevents 'em from breaking down in the can. A must have for any type of EFA supplement. This translates to ultra potent softgels right from the get-go. This also ensures that Omega helps maintain muscle function and immunity. All in all, Animal Omega provides essential nutrition for the bodybuilder. It's loaded with all of the right fats, in a proper amounts to help support high quality metabolic functioning, heart function, healthy triglyceride levels and blood pressure.
