    Additional Information

    Where and from whom do we get our Alaska Cod?

    The Alaska Cod is wild-caught in the Bering Sea along the Aleutian Islands of Alaska. Our partner Alaskan Leader fish for Alaska Cod in these pristine waters using a “Hook & Line” technique.

    How do we to make sure that our Fermented Cod Liver Oil is of high quality?

    Quality is our top priority. 3rd party laboratories extensively test our products to ensure safety and quality. Check out our Quality and Sustainability page and learn more about our oils.

    Read about why we only use non-gelatin capsules.

    Why do we use fermentation to extract the cod liver oil?

    Throughout much of human history fermentation has been used to extract cod liver oil, and other fish oils. Recently Dr. Martin Grootveld’s research has found that this traditional method of extraction allows for natural antioxidants to be present and shields the fragile omega fatty acids. Find out more about fermentation and Dr. Martin Grootveld’s research by visiting our Fermentation page.

    How does nutrition affect oral health?


    Dr. Weston A. Price pioneered research into nutrition and oral health. He found that a traditional diet rich in nutrients had a beneficial effect on oral health. In The Fat-Soluble Vitamins Beat Cavities Ramiel Nagel explores this research and more.

    What is the historical background of cod liver oil?

    Primitive Norse populations and ancient Romans consumed nutrient–rich fish oils extracted using fermentation. They knew of the health benefits found in these oils. Once vitamin D was found to be present in cod liver oil it became an important component of treatments against rickets.

    View our blog posts The Historical Roots of Fish Liver Oil, The fermenting of fish and fish by-products: fish sauces in ancient medicine and cuisine, and Historical Perspectives of Cod Liver Oil.

    Is there vitamin E in cod liver oil?

    Natural vitamin E is present in our Fermented Cod Liver Oil because of the nature of cod, and our extraction method. To learn more visit our blog post Did You Know That There is Naturally Occurring Vitamin E in Cod Liver Oil?.

    Frequently Asked Questions

    How do you make Fermented Cod Liver Oil?

    Fermented cod liver oil is a natural product that is made by the prolonged soaking of wild cod livers in brine, allowing the liver to naturally ferment, then draining off the resulting oil that accumulates on the top. Read more: Fermented Cod Liver Oil: A Traditional Food.

    Is Fermented Cod Liver Oil rancid?

    Rancidification is more related to taste and odor. However, these flavors are desirable for lot of products, specially for fermented foods, such as aged cheese, fish sauce, etc. We tested our fermented cod liver oil for rancidities, and presented the results to scientists for analysis. Their conclusion is the fermented cod liver oil is not rancid.

    Can you actually ferment oil?

    The name was derived from the process used to extract the oil from the liver. The livers are fermented, not the oil. Fermentation is a natural process where the cell membrane ruptures and the lipids are released from the tissue. It is an enzymatic and bacterial digestion of the liver. This breakdown is the similar to the process that takes place in one’s digestive system. It is not complicated, but does take time to complete. The result is a light to dark brown oil that contains hundreds of molecules within the fatty acid structures. There is nothing new about fermented fish products. They have been around for thousands of years and are readily available and consumed to great healthful benefit in many parts of the world, even today.

    Is Fermented Cod Liver Oil safe to take?

    Safety is always our first priority. All of our products go through third party testing multiple times to ensure the safety of each lot.

    What color oil is better?

    We have not found nutritional differences in our medium to darker colored oils. When we tested a variety of factors such as hormonal, bone healing, and toxicity through a biofeedback practitioner, the darker oil was slightly better when testing hormones, but it was not a statistical study from which to draw conclusions. There is a book from 1849 that includes some research on this topic: The Three Kinds of Cod Liver Oil.

    The focus of the book was to study the 3 different types of Cod Liver Oil; Pale, Light Brown and Brown Cod Liver Oil. The author, L.J. DE Jongh MD, writes: “The brown Cod Liver Oil has proven itself a most powerful remedy in rheumatism and scrofula. Now, I have found, in my chemical analysis, a quantitative difference between this and the other sorts of Cod Liver Oil. The constituent parts, which exist in great proportions in the brown Cod Liver Oil, must, therefore, be considered as those which fulfill the most important indications. The neutral fat, the iodine, phosphorus, the inorganic salts, exist in the same proportions in the other kinds of oil, which are not supposed to be particularly efficacious in scrofula and rheumatism; it is, therefore, fair to assume that the brown Cod Liver Oil owes its great power to the biliary matter and butyric acid, which exist in it in much larger proportions than in the lighter-coloured [sic] oils.”

    Why do some experience digestive discomfort when they first start to take Fermented Cod Liver Oil and others do not?

    We are aware that some people do experience digestive discomfort when they take the Fermented Cod Liver Oil or other fish oils. Unfortunately, we do not have a clear answer for this. A possible explanation maybe be allergies or intolerances, low bile secretion, etc. We suggest the customer stop taking Fermented Cod Liver Oil and check with a health practitioner.

    Are trans fat in fish and fish oil, including cod liver oil?

    Trans fats are naturally occurring at low levels. Fish meat, fish tissue and fish oils have trans fatty acids, which are part of their natural composition. Cod liver oil does have a small amount of natural trans fatty acids.

    Read more about trans fatty acid in  Fermented Cod Liver Oil that addresses this question: “You have routinely had commercial analytical labs analyze samples of your fish oil. The data obtained did not show trans fatty acids, that is, if trans fatty acids did exist, they were present at a very low level. In general, fish oils may contain very low levels of trans fatty acids. Low levels of trans fatty acid may naturally present in bovine milk fat (0.6 – 3.9%) (MÃ¥nsson, 2008), beef meat (3.6%) (Woods & Fearon, 2009), and dairy creams (3.02 to 4.11g/100 g) (Jan et al., 2011). This may be the result of microbial hydrogenation of cis-unsaturated fatty acids in the stomach of ruminant animals (Bauman & Griinari, 2003).”€“ Subramaniam Sathivel, Ph.D. Also, please see the Scientific Analysis by Subramaniam Sathivel, Ph.D, who states that Small amounts of trans fatty acids are naturally occurring in fish, including cod liver oil.

    What is the natural source of vitamin D in the sea?

    Small of organisms found in the ocean contain vitamin D. These organisms include phytoplankton, zooplankton, and related species. They have both vitamin D2 and D3 in a healthful supply. Fish do not produce vitamin D via the sun as humans do. There is very little known about the pathway of vitamin D in fish and their effects within the food chain. The theory is fish will accumulate vitamin D by eating those organisms.

    What is the Essential Fatty Acids content found in Fermented Cod Liver Oil?

    We do not have a specific focus on the fatty acids in our Fermented Cod Liver Oil. These fatty acids are not the focal point of the product.

    Everyone takes different amounts of our products. To obtain an approximate content level of fatty acids, please use the following conversion to calculate.

    5ml = 5g = 5,000mg = 1 tsp.

    X = the amount of Fermented Cod Liver Oil product you take
    Y = The approximate % of the fatty acid found within the product, which is 10%.
    X mg x 10% [Y] = mg of intake

    So , how many mg of DHA am I getting if I take 1 tsp of Fermented Cod Liver Oil each day?

    5,000mg x 10% = 500mg of DHA per tsp.20
