BORAGE OIL contains high amounts of the essential fat gamma linolenic acid (GLA), an omega 6 fatty acid that is essential for metabolism but cannot be produced in the body. GLA helps support cartilage and joint function, dilates smooth muscle, maintains healthy nerve function and helps maintain cholesterol levels that are already in the normal range. It also alleviates common symptoms associated with PMS. Borage oil has the highest content of GLA of any plant source.
