Natural Factors OmegaFactors Ultra Prim Evening Primrose Oil is derived from the highest quality evening primrose (Oenothera biennis) seeds, and extracted by cold pressing (expeller pressing) without the use of hexane or other solvents. 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) in each softgel.
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.
Natural Factors Ultra Prim is made from the highest quality evening primrose oil, extracted using a gentle method called cold pressing. This method crushes the seeds to release its nutritional oil, without the use of heat or any other harsh solvents such as hexane. Cold pressing enhances the stability and preserves the nutritional components of the oil. Ultra Prim is also ultra-purified to remove any organic residues or impurities.
