EFAs play an important role in many of the body's vital biological actions such as fat metabolism, cellular function and healthy skin. Sci-MX's powerful new Tri-Omega EFA is formulated using the four highest potency sources of EFA's, namely coldwater fish oil, flaxseed oil, evening primrose oil and blackcurrant oil. These four sources supply an ideal ratio and quantity of Omega 3, 6 and 9 fatty acids, including EPA/DHA gamma-linolenic acid and alpha-linolenic acid. Vitamin E has also been added, which naturally prevents the oxidation of omega oils. Each concentrated softgel contains 1000mg of EFA's, making this one of the strongest formulas available. Every batch is tested to ensure that it is free of ocean-based toxins, mercury and contaminents. Essential Fatty Acids Play an important role in the rebuilding and production of new cells, the metabolism of body fat, and many other vital health functions. These fats cannot be produced by the body and need to be supplied through diet or supplementation.
