Black Currant Oil is a rich source of gamma linolenic acid, GLA, along with other important polyunsaturated fatty acids. Fatty acids are involved in many body functions, such as maintaining body temperature, insulating nerves, cushioning and protecting tissues and creating energy. These essential fatty acids are precursors of prostaglandins, which must be present for functions involved with dilating blood vessels, regulating arterial pressure, metabolizing cholesterol, activating T-lymphocytes, pretecting agtainst platelet aggregation, controlling abnormal cell proliferation, and other functions. Before the discovery of black currant oil, the only other known sources of GLA were mother's milk and evening primrose oil.
