Black Currant Oil [Immune] is a rich source of gamma linolenic acid, GLA, along with other important polyunsatura-ted 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, protecting against platelet aggregation, controlling abnormal cell proliferation, and other functions. Before the discovery of black currant oil, the only other known sources of GLA were mothers milk and evening primrose oil. Each black currant oil capsule contains 1618 percent GLA (more than evening primrose oil), provides two essential fatty acidslinoleic acid and alpha-linolenic acidand the unique stearidonic acid
