Evening primrose oil supplies another fatty acid, known as gamma-linolenic acid, or GLA (not to be confused with alpha-linolenic acid, which is one of the omega-3 fatty acids). You actually don’t need to consume GLA, because your body synthesizes it from linoleic acid and converts it to hormone-like chemicals important in maintaining health.
