Evening Primrose oil is a natural source of the very important nutrient, gamma-linolenic acid (GLA), a member of what chemists call the omega-6 family of fatty acids. Fatty acids are important constituent parts of all fats. The body makes GLA from linoleic acid, the head of the omega-6 family line. Linoleic Acid is found in common vegetable oils with omega-6 content, such as corn oil, canola oil, safflower oil, sunflower oil, soybean oil, peanut oil, sesame oil and olive oil. For many North Americans, conversion of linoleic acid to GLA is difficult because their bodies lack adequate levels of vitamins B6, B3, magnesium and zinc. Furthermore, the conversion is blocked in proportion to the amount of trans-fatty acids and saturated fat in one"s diet, which in North America can be significant. Trans-fatty acids are created by the extreme high temperatures of standard oil processing and partial hydrogenation. Supplementing with Evening Primrose oil, by-passes the need to rely on the biochemical creation of GLA inside the body from linoleic acid. Evening Primrose oil is used to treat premenstrual syndrome (PMS), demonstrating meaningful benefits in up to 90% of users. It can help to lower risk for or manage arthritis, helps in diabetic neuropathy, improves hair, nails and skin. It can also help lower the risk for stroke and heart attack by lowering platelet stickiness and inappropriate blood clotting. These statements have not been evaluated by the FDA.
