Maxi Premium EPO (now in soft gels) is a combination of hexane-free evening primrose and flaxseed oils, which provide essential fatty acids. Evening primrose oil is rich in essential fatty acids, polyunsaturated fats, which are as essential as vitamins and minerals for the maintenance of good health. The oil contains 74 percent linolenic acid (LA) and 8-10 percent gamma-linolenic acid (GLA), better known as Omega 6 oils. Flaxseed oil, another important polyunsaturated fatty acid is an omega-3 fatty acid. Alpha-linolenic acid (ALA) is found in high amounts (50 to 60 percent) in flaxseed oil and some vegetables. Approximately 10 percent of Alpha-linolenic acid (ALA) is transformed in our bodies into two other fatty acids: EPA and DHA (compounds found in fish oil). Consuming flaxseed oil may be particularly important for vegetarians who do not eat fish. Flaxseed oil is nature's most abundant source of lignans. Lignans are naturally-occurring substances found in plants and are classic.
