In all Nordic Naturals formulas, we use natural antioxidants (vitamin E, for example) to help preserve the freshness of the oil. In many formulas, we also use natural fruit flavors to augment the palatability of our oils. Because these natural components are present in the soft gels, occasionally they can collect and concentrate at a specific point in the soft gel— which can create a discolored spot. This spot may dissipate when shaken, or may stay in a fixed place in the event that the spot adheres to the wall of the soft gel.
