Country life's evening primrose oil is a natural source of GLA (gamma linolenic acid) and LA (linoleic acid) fatty acids. Country life uses no hexane or other harmful solvents during extraction. GLA is an omega-6 fatty acid involved in human metabolism. Evening Primrose Oil is one of the richest sources of Gamma Linolenic Acid (GLA), an essential fatty acid that provides the building blocks for female hormones. It thereby helps to provide hormonal balance. It plays a key role in female metabolism by maintaining hormonal balance, healthy skin and supple joints. Evening Primrose has been found to be effective at reducing menstrual cramping, bloat, water retention, breast tenderness and irritability due to hormonal shifts during a women's cycle. Evening Primrose Oil with its health-promoting properties provides a better chance to manage imbalanced hormones. Many women find that evening primrose oil offers relief from common symptoms of premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD), particularly mood swings, breast tenderness and menstrual cramps. It is thought that GLA's ability to regulate prostaglandins helps to reduce the body's inflammatory response to hormone fluctuations that occur around menstruation. Being healthy is essential to being happy and Country Life believe that good health is an important part of treating yourself well.
