Evening primrose oil is an oil produced from plants belonging to the Oenothera L. family - most often from the seeds of evening primrose biennial, a plant originating from North America, which can currently also be found in Europe. Evening primrose oil is distinguished by its richness of essential fatty acids - In particular, it contains linoleic acid (LA) and gamma-linolenic acid (GLA), i.e. compounds belonging to the group of polyunsaturated omega-6 acids. Because the human body is not able to naturally synthesize these substances, it is worth delivering them to the body along with the daily menu or in the form of dietary supplements.
