Borage oil is a nutritional oil containing polyunsaturated fats. Linoleic acid and Gamma Linoleic Acid (GLA) are enhanced essential fatty acids. Although the body can manufacture GLA from dietary linoleic acid, it can be more efficiently utilized for bodily functions when supplied directly by dietary sources. Borage oil is a more concentrated source of GLA than Evening Primrose Oil (EPO). One NOW Foods Borage Oil softgel is equivalent to about 5 standard EPO softgels in GLA content.
