Fermented Cod Liver Oil is made in small batches with extraordinary care. Green Pasture ferments livers from fish that have been exclusively wild caught in the Bering Sea/Aleutian Islands region.
Fermentation is a natural enzymatic and microbial action that releases the oil from the livers. This Fermented Cod Liver Oil is a raw, unadulterated, whole food. There are no additives of any kind. It is routinely third-party tested for purity.
This entire product line is certified by the Marine Stewardship Council, which ensures that the cod livers we source have been sustainably wild-caught. (MSC-C-55178)
It is well known to chemists that chemical extraction of oils results in isomers. What this potentially means is 50% positive and 50% negative versions of the extraction - potentially causing as much harm to the human body as good. Alternatively, heat extraction can destroy many of the chemical bonds that are essential in providing goodness to us. Fermentation methods are rarely used due to the time-intensive nature of the process. The quality and benefit in doing so, however, is unparalleled.
The product is extracted using a proprietary cold process extraction and cleaning method and is independently tested to internationally recognised purity standards. Fermented Cod Liver Oil is typically far easier to digest than regular cod liver oil, resulting in increased absorption - including 2.5 times more Vitamins A and D.
