Evening primrose stands out for its richness in essential fatty acids (gamma-linolenic and gamma-linolenic acid - GLA) necessary for the correct production of prostaglandins (precursors of hormones capable of regulating many functions of our body). A lack of GLA triggers a series of problems such as dryness and skin irritations, abnormalities in the liver, alterations in the production of prostaglandins and even growth problems in children. In addition, evening primrose has regulatory effects on estrogen, progesterone, prolactin and prostaglandin levels, which makes evening primrose oil a great ally to combat pre-menstrual symptoms (fluid retention, irritability, abdominal pain). GLA is found naturally in the triglycerides that form vegetable oils, in vegetables and in some nuts; however, one of the best sources is evening primrose seed. The need for a supplemental supply of evening primrose oil increases every day in modern society; where the intake of vegetables, vegetables and unsaturated oils is decreasing. The usual amount of GLA in evening primrose oil is 9%, but higher qualities reach up to 10%. The incorporation of vitamin E, tocopherol, into the formula is as a cellular antioxidant and to protect the oil from rancidity, thus ensuring the good condition of the oil.
