Evening Primrose is a flowering plant native to the temperate and subtropical regions of North America. It's a natural source of linoleic acid (LA) and gamma linoleic acid (GLA). These omega-6 fatty acids are known to support healthy skin and mild PMS-related discomfort in women. The Vitamin Shoppe® brand Evening Primrose Oil features 76mg of GLA and 544mg of LA per each once-daily softgel.
