What are the properties of GLA in supplements?

The properties of GLA

Gamma-Linolenic Acid (GLA) is a omega-6 fatty acid found primarily in vegetable oils. When acting on GLA, arachidonate 5-lipoxygenase produces no leukotrienes and the conversion by the enzyme of arachidonic acid to leukotrienes is inhibited.

GLA is obtained from vegetable oils such as evening primrose (Oenothera biennis) oil (EPO), blackcurrant seed oil, borage seed oil, and hemp seed oil. GLA is also found in varying amounts in edible hemp seeds, oats, barley and spirulina. Normal safflower (Carthamus tinctorius) oil does not contain GLA, but a genetically modified GLA safflower oil available in commercial quantities since 2011 contains 40% GLA. Borage oil contains 20% GLA, evening primrose oil ranges from 8% to 10% GLA, and black-currant oil contains 15-20%. It also constitutes 12.23% of the fats from the fruit of the durian species Durio graveolens.

Sources of Gamma-Linolenic Acid in diet:

  • Found in minor amounts in vegetable oils and meat.
