Green Pasture's fermented cod liver oil is head and shoulders above any other cod liver oil product. Conventional cod liver oil products under go so much processing that they are often damaged and have little or no nutritional benefit to the consumer - not this one. Blue Ice fermented cod liver oil is not processed with any heat or pressure, it is processed exactly as it says - fermented. This ensures that none of the nutrients in this product are damaged. The fermentation process provides a number of other health benefits as well!
