Evening Primrose Oil

Herbal Supplements

Evening Primrose Oil, derived from the seeds of Oenothera biennis, is valued primarily for its rich concentration of gamma-linolenic acid (GLA), an omega-6 fatty acid involved in inflammatory and hormonal pathways. Research suggests that GLA supplementation may support relief from premenstrual symptoms such as breast tenderness and mood changes, and some studies indicate potential benefits for skin conditions like eczema by helping restore moisture and reduce inflammation. There is also emerging interest in its role in supporting nerve function, particularly in individuals with metabolic health concerns, as well as modest evidence around joint comfort. While findings across studies vary in strength and consistency, Evening Primrose Oil remains one of the more widely researched herbal oils, with a long history of traditional and complementary use for hormonal and inflammatory support.
