This ultra-purified source of omega-6 essential fatty acids is highly stable and free of preservatives, offering gamma-linolenic acid (GLA) and cis-linoleic acid (LA). The essential fatty acids in Ultra Prim play an important role in the management of inflammation, cholesterol levels, hormonal balance, eye and skin health, and circulation. Ultra Prim may help prevent cardiovascular disease, reduce the risk of dangerous blood clots, and support healthy blood pressure. Due to its beneficial effects on the immune system, cell membranes, and hormonal balance, GLA helps ease symptoms associated with premenstrual syndrome (PMS) and atopic eczema. GLA supports the health and appearance of the skin, can decrease inflammation, and even offers relief from dry eyes for contact lens wearers. Evening primrose oil is an important source of GLA for anyone who wants to increase their intake of this omega-6 essential fatty acid.
