GLA (gamma-linolenic acid) is an 18C fatty acid of the omega-6 series which is present in nature in several vegetal seeds oils (oenothera, borage, currants); it is also physiologically synthesized by the organism as a metabolita of linoleic acid, used by mast cells to produce soothing and anti-inflammatory PGE1 prostaglandins.

GLA’s effect in counteracting the production of pro-inflammatory prostaglandins has made GLA-containing oils the subject of a series of clinical trials. The use of GLA-containing oils has shown promise in helping people improving joint flexibility, favoring certain aspects of nerve function and improving quality and aspect of the skin in case of dermatitis and eczema.
