This Golden Flax Seed Oil™ uses an exclusive cold-pressed process to ensure that you are buying the highest quality, freshest oil available. The organically grown flax seeds are harvested at their peak, sorted and cleaned. The seeds are pressed and bottled without any bleaching, filtering, refining or additives, using only the first pressing (virgin oil). This exclusive process ensures that the oil is not exposed to damaging light, heat or oxygen during the extraction or bottling process. The special opaque black bottle protects the delicate oil from free-radical damage caused by light and the bottle is easily recyclable.
