Evening Primrose Oil is the oil from the seeds of the plant, evening primrose. It is primarily used as a food supplement for the omega-6 essential fatty acids it contains, GLA (gamma-linolenic acid). GLA is needed in the body for the production of hormone liked chemicals called prostaglandins E1, (PGE1) which control numerous mechanisms such as inflammation, blood pressure, cholesterol regulation and hormone regulation to name a few.

Our bodies can normally convert other essential fats found in the diet into GLA, however nutritional deficiencies, saturated fat, alcohol and abnormalities can block this conversion. This causes a deficiency in PGE1 which can lead to many health problems. Evening primrose oil supplementation gives the body a direct source of GLA and therefore is very useful for health maintenance.
