For centuries, EPO has been used to provide nutritional support for women with premenstrual syndrome (PMS); it may also play a role in promoting smooth, healthy-looking skin.** These easy-to-swallow softgels are a natural source of GLA (Gamma Linolenic Acid). Our EPO contains one of the most biologically active forms of this Omega-6 fatty acid available today. The Primrose Oil used for Vitamin World is 100% pure, solvent free, cold pressed and void of hexane and other solvent residues. Many factors can affect the body’s ability to convert Linoleic Acid into GLA. These include aging, intake of certain nutrients such as zinc, B6, magnesium, biotin and calcium, stress, and cholesterol levels. This is why supplementing with Evening Primrose Oil, a natural source of GLA, can be so important for overall, women’s health.**Contains 120 rapid-release softgels.
