Evening Primrose Oil and Borage oil are basically the same. The Borage oil softgels are a better bargain because they contain 30% more of the all important oil GLA than the Primrose Oil. However, the Borage Oil softgels are twice the size of the Primrose Oil Softgels. The Primrose are about the size of a Vit E softgel. When choosing which of these oils to buy, you will need to take into consideration your child's swallowing ability/preference. Each softgel contains 500mg Evening Primrose Oil, including 45mg of GLA. This is one of the three essential fatty acids in Dr Jacqueline Stordy's formula for children's learning and attention. NOTE: This product cannot be returned for a refund.
