For a general essential fatty acid supplement, flaxseed oil may be the best choice for most people. Optimum Nutrition's Flaxseed Oil Softgels are produced from oils that have been carefully extracted without the use of hexane or added heat. This cold extraction process helps to preserve the delicate chemical structure of Omega-3, Omega-6 and Omega-9 fatty acids that are so naturally rich in Flax seeds.
