Stearidonic acid is present in a several plant seed oils. The most importance dietary sources of this fatty acid are the seed oils of hemp(2-3%) and blackcurrant (2-4%).
The seed oils of many plants species of the Boraginaceae family contain stearidonic acid between 10% and 20%.
Hempseeds also contain gamma-linolenic acid (GLA). Both Stearidonic acid and gamma-linolenic acid in conjunction can help treat symptoms of atopic dermatitis and other skin disease.
Research in 2003 showed that consumption of 0.75 or 1.5 g stearidonic acid increased the EPA and DPA content of red blood cells and plasma phospholipids.
Many clinical trials studies suggest that there is good evidence to show the positive of several human disease.
Health effects by these essential fatty acids include alteration of plasma lipids profiles, reducing the risk of coronary atherosclerotic heart disease, dermatitis, platelet aggregation, rheumatoid arthritis and blood pressure.
Sometimes it is called moroctic acid. It is biosynthesized from alpha-linolenic acid by the enzyme delta 6-desaturase.
