This oil is 100% pure, organically grown and cold-pressed using the Barlean's BioElectron process which preserves the lignan containing fibers within the oil. Lignans are a class of plant fibers that have been studied extensively for their valuable potential health benefits. Flaxseed has been found to contain 100-400 times more lignan-containing fibers within the oil. It is bottled in special, high-density polyethylene resin bottles designed to have an appropriate combination of environmental stress and crack resistance; perfect for live foods like flaxseed oil. Also available in convenient softgel capsules, each supplying twice the amount of omega-3 fatty acids as the typical fish oil supplement.
