Borage Oil is a nutritional oil containing over 80% 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 body functions when supplied directly by dietary sources. Borage Oil is a more concentrated source of GLA than Evening Primrose Oil (EPO). One Borage Oil capsule is equilvalent to about 5 standard EPO capsules in GLA content.
