Cod Liver Oil (Fermented) Liquid

Sold out - please see here for further details

ALL Cod Liver Oil in the World is molecularly distilled. Synthetic vitamins A and D  are put back in because the nutrients are destroyed during intense industrial processing! 

EXCEPT this one - the incredible, and unique Blue Ice Cod Liver Oil. It's fermented using traditional methods combined with the quality and assurance of modern manufacturing.

The liquid is best value giving you 4 months supply, but we also have capsules.

It’s the richest natural source of the valuable vitamins A & D, in an easy to absorb form and packed with valuable Omega oils.  Also present are an incredible amount of healthy co-factors and nutrients such as quinones vitamin K, vitamin E and CoQ enzymes.

And the traditional lacto-fermentation process also transforms aspects of the natural vitamins into different metabolites that are readily easily absorbed by your body. You get many more nutrients (in a totally natural form) than you do with cheap, refined oils.

Fermenting fish livers has thousands of years of healthy tradition.  During the industrial revolution in the 1850s, Cod Liver Oil’s quality was completely compromised in the name of mass production. Around 100 years later, it became standard to process Cod Liver Oil so heavily, that synthetic vitamins are added back in (and not in the right balance!)

That’s why you wont see the breakdown of the amounts of Vitamins A and D in this wonderful traditional food, you can read more on this issue below.

Wild caught from the clean, pure waters of the Arctic to excellent marine stewardship standards. Produced by Green Pastures a family firm, in certified, GMP premises in the USA.  Independently tested, guaranteed free from man-made PCB's and heavy metals.

Why Arent the Vitamin A and D Amounts Specified?

From the Green Pasture Company

The concern that facilitated the discussion about what nutrient content to list on the Fermented Cod Liver Oil label, is that there are a wide range of test results on method and lab. In addition, there are thousands of nutrients within Fermented Cod Liver Oil including many minor forms of A/D that are not currently discussed.

The FDA views a dietary supplement like a drug, but the Fermented Cod Liver Oil is more like a food. Drugs have 'known' amounts of very specific ADDED nutrients (if one wants to call lab made molecules nutrients). Lab nutrients can be easily measured and reported.

After working with the product for 5 years our conclusion is that media medicine and FDA label requirements do not fit the Fermented Cod Liver Oil. It is like putting a square peg in a round hole. It is beyond vitamin A and D. It is not proper to tie Fermented Cod Liver Oil into a standard CLO discussion nor can the product accurately be defined in these terms. We get questions about A / D / EPA / DHA and we do discuss openly and as a result sometimes people struggle to understand the concept that the Fermented Cod Liver Oil  is not a drug and it is not as easy as it has exactly 842iu's of vitamin D per ml and this will do this or that in your body.

The product cannot be defined in standard media medicine terms and there is no need to know these things other than discussion and intrigue as the product is what it is as it has been for thousands of years (prior to the industrialization of fish oils). Not knowing this or that does not change the product nor how one should use the product.

Our new labels will have the familiar design you’ve come to recognize, however, quantities of Vitamins A & D will no longer appear on the label. Instead, we’ve moved detailed information about our testing results to our web site. Along with random testing results of Vitamin A & D found in our products, we’ll also be providing information on pollutants like heavy metals and PCBs - none of which fits into the small space of a label.

There are numerous forms of Vitamin A & D. Nutrient pioneer, Dr. Royal Lee, identified over 160 forms of Vitamin A alone. We test our products for just two of those forms - a daunting enough task.

In testing our Fermented Cod Liver Oil, we noticed some of the minor forms of Vitamin A identified by Dr. Lee. Since Vitamin A is broken down into minor forms during the natural digestion process, our research results are not surprising. We believe these minor forms have additional health benefits that can’t be represented on a label.

Similar variability and testing struggles are present in Vitamin D. Hundreds of forms are possible, but in the end only two are commonly measured.

Our former label reported the average amounts of Vitamins A & D present in the random testing of our Fermented Cod Liver Oil, but this is no longer permitted by the FDA. Current standards call for the testing of each batch produced to meet minimum FDA requirements. But as we’ve pointed out, the variables of natural foods are too numerous to ensure that each batch will contain a consistent amount. And it is not practical to test each batch as our batches are small compared to mainstream manufacturers.

Because of this, the challenge we face is determining how to present this information on a label.

In general, the industrialized food model meets label requirements by adding specific amounts of synthetic vitamins that are easily measured in a lab and reporting those on their labels. Green Pasture Products is committed to providing high quality real food and will not use synthetic vitamins, regardless of the consequences.

One option we considered would be to show the lowest possible amount of Vitamins A& D based on any batch, but this does not give you an accurate picture of the nutritional value of our products. As such we have decided to remove this information from our labels and make it available on our website – where it makes sense. The random test data that will be provided will not be for any one specific lot or jar but is for general discussion.

We will not compromise our products simply to satisfy FDA labeling requirements. We prefer to offer products as they have been available for thousands of years – without regard to today's industrialized media-driven, food-labeling requirements.

A decade ago, the main reason physicians ordered a vitamin D test was if there was a concern about the patient’s bone density. However, a flurry of research now has implicated the prohormone in a host of conditions, including among others, certain cancers, type 1 diabetes, multiple sclerosis, tuberculosis, Alzheimer’s disease, psoriasis, and all-cause mortality, while also indicating that vitamin D insufficiency is prevalent. Even though vitamin D’s mechanism of action in the prevention or progression of various diseases has not been established definitively, these studies have been picked up by the popular press, causing demand for vitamin D testing to skyrocket. At the same time, there have been notable technological advancements in vitamin D testing, controversies surrounding certain tests, and considerable confusion about both analytical considerations and clinical interpretation of vitamin D results, leaving laboratorians and clinicians unsure about how to implement or interpret the test properly.

“There’s significant confusion out there,” agreed Hershel Raff, PhD, director of the endocrinology research laboratory for ACL Laboratories and professor of medicine at the Medical College of Wisconsin in Milwaukee. “Vitamin D testing aas becoming part of the routine physical in Wisconsin, but some doctors don’t really understand what they’re ordering, so they check off anything that looks close.” Raff believes the vitamin D naming conventions only muddy the waters: 25-hydroxyvitamin D2 also is known as ergocalciferol, 25-hydroxyvitamin D3, as cholecalciferol, and 1,25 (OH)2 D, as calcitriol. Some doctors mistakenly think 25-hydroxyvitamin D2 or 25-hydroxyvitamin D3 is the same as 25-OH-D or 1,25 (OH)2 D.

In concert with the confusion about which vitamin D test to order, there is no consensus about the appropriate reference range and cut-offs for deficiency or insufficiency, as well as optimal and possible toxicity status.

Yet another level of confusion exists as a result of several lingering analytical issues with the various assays.

According to Rao, it is not uncommon for physicians to receive vitamin D test results for the same patient but from different labs that have used different assays and produced different results, putting laboratorians in a spot to explain the discrepancies.

Even as there has been a trail of confusion in vitamin D analytics, there is, in the eyes of many, hope on the horizon.

While LCMS is becoming the preferred analytical method of many reference labs and has been called the gold standard for measuring vitamin D, not all lab directors see it that way.

As the vitamin D field continues to evolve, there are steps laboratorians can take to improve vitamin D testing proficiency and inform the medical community about the test’s appropriate use. Raff spends a good bit of time educating physicians one-on-one, in group presentations, and in writing, including in an internal newsletter that detailed the biochemistry of vitamin D and the differences between 25-OH-D and 1,25 (OH)2 D testing and their respective indications.

While the industry awaits analytical improvements and further clinical evidence about vitamin D, laboratories will be challenged to maintain high-quality testing and keep physicians well-informed about testing indications. As Carter put it, “We’ll just have to grit our teeth.”

Because this Cod Liver Oil is fermented, not heat treated and retains its enzymes, it will not degrade 


I am a family practice physician in Pasadena, California. I have been using Green Pastures fermented cod liver oil and high-vitamin butter oil with my patients for only nine months now, and I have noticed dramatic results. The most dramatic of these is the effect the oils have had on lowering blood pressure in patients with hypertension. This effect has enabled several of my patients to lower their dose of prescription medication, and hopefully eliminate it all together. In addition, I have found that patients have lost weight and lowered their blood sugars without any change in diet or activity. I have also had reports of less stiffness and pain of joints in arthritic and temporomandibular joint dysfunction patients, improvement in eczema, elevated mood in depressed patients, lessening of symptoms of PMS and increased energy and overall well being. I have a very small practice so these testaments are drawn from a few patients here and there, but they are indicative of tremendous benefits for a large number of people.

Because Green Pastures fermented cod liver oils and butter oils contain such a wide variety and potency of fat-soluble nutrients, they not only enhance my patients lives, but simplify them as well. Patients are able to take much less cod liver oil than with their old brand and eliminate the need for additional supplements, which are lacking in other brands.

Last year I'd heard a whole lot about this fermented cod liver oil.  People swore it was amazing stuff.  They also said it was really nasty to take.  I held out, because it's expensive.  What if I didn't like it?  What if it really wasn't that amazing?  I'd be out a whole lot of money.

Then it was fall.  We were heading into the winter and I knew it wasn't going to be fun.  I'm sure our vitamin D levels weren't optimal then, and they'd only get worse as we were kept inside all winter long.  Plus, we had one nasty cold in August and I did not want that repeated constantly for months.  The solution, according to many, was Green Pastures Cod Liver Oil/Butter Oil blend. I haven't found any other supplement that makes a difference the way this one does.  And in the past, I have tried other fish and even cod liver oils.  I've tried probiotic supplements, vitamin C, vitamin D, and so on.  I never noticed any real impact from any of those.  But this product clearly has made a difference for us. I feel like this just boosts our immune system so strongly that we are able to fight off illnesses very easily.  After we tried our first bottles, I didn't care what it cost to keep buying it (it's not cheap), I was going to do whatever I could to make sure we always had it around.  And I have.  I don't consistently take or give my children any other supplements on a regular basis. I have been taking cod liver oil for a whole month now, and want to share how cod liver oil has benefitted me. As I mentioned above cod liver oil has greatly helped me with my asthma symptoms. I have only used my inhaler 2 or 3 times. This is a major breakthrough, considering the fact that it is fall, the time of year I need my inhalers constantly. I am so happy to not need such harsh medications anymore. Also, I have suffered from eczema on my hands and this month it has improved immensely. I have even started just putting the oil directly on my hands. They are still very dry, but they do not get inflamed and itchy or crack anymore. I also noticed during this months cycle I did not get any kind of headache or pain. In the past year my PMS has decreased immensely, but I would still get slight headaches at the end of my period. Not this month, thanks to the cod liver oil. I'd like to note that I am taking 2 teaspoons of Green Pastures Fermented Cod Liver Oil daily. One bottle lasts me about a month, to stretch it, some of the days I take a single dose. The benefits of cod liver oil are just too many to ignore, I highly recommend adding it to your daily regime.?
