Overview
Gamolenic acid, or gamma-linolenic acid (γ-Linolenic acid) or GLA, is an essential fatty acid (EFA) comprised of 18 carbon atoms with three double bonds that is most commonly found in human milk and other botanical sources . It is an omega-6 polyunsaturated fatty acid (PUFA) also referred to as 18:3n-6; 6,9,12-octadecatrienoic acid; and cis-6, cis-9, cis-12- octadecatrienoic acid . Gamolenic acid is produced minimally in the body as the delta 6-desaturase metabolite of Linolenic acid. It is converted to Dihomo-gamma-linolenic acid, a biosynthetic precursor of monoenoic prostaglandins such as PGE1. While Gamolenic acid is found naturally in the fatty acid fractions of some plant seed oils , Evening primrose oil and Borage oil are rich sources of gamolenic acid. Evening primrose oil has been investigated for clinical use in menopausal syndrome, diabetic neuropathy, and breast pain, where gamolenic acid is present at concentrations of 7-14% . Gamolenic acid may be found in over-the-counter dietary supplements. Gamolenic acid is also found in some fungal sources and also present naturally in the form of triglycerides . Various clinical indications of gamolenic acid have been studied, including rheumatoid arthritis, atopic eczema, acute respiratory distress syndrome, asthma, premenstrual syndrome, cardiovascular disease, ulcerative colitis, ADHD, cancer, osteoporosis, diabetic neuropathy, and insomnia.
