Codliveroil also has vitamins E and K, which tend to be scarce in modern human diets. Codliveroil also contains CoQ10, an enzyme vital for cell growth and energy. Cod liver oil has also been linked to symptom reduction for inflammatory bowel diseases and arthritis, to improved heart health and lowered triglycerides, as well as to better cognitive health, even for people with degenerative neural disorders like Alzheimer's and dementia.
Lori Kenyon Farley, a certified nutrition consultant specializing in wellness, fitness, and anti-aging and one of the experts behind Project Juice, adds a few more benefits to the list, including regulating blood sugar, prevention and healing of acne, and prevention of hair loss.
She also notes that, "Although there are other ways to obtain vitamin A, and vitamin D unless you live in a climate without much sunlight , there are fewer sources of Omega 3 fatty acids. Sounding great so far, right? And while cod liver oil isn't all that pleasant, it's not nearly as funky-tasting as the fermented stuff. It only works if you take it. Lacto-fermented processing is the original means of production of cod liver oil So opting for fermented cod liver oil from the get-go gives you a much purer, more natural product.
But synthetic vitamins aren't the only worry. Christina Major, a MS holistic nutritionist and herbalist and the health recovery expert of Crystal Holistic Health, says that the vitamins A and D that remain in the heat-processed oil have been linked to heart disease.
Scary stuff, right? It's no wonder that some experts began advocating for the naturally fermented version of the product, including Parikh. The fermented cod liver oil is attributed to boosting the immune systems of people with auto-immune diseases, and these benefits stem directly from the fact that the oil is fermented.
This information is backed up by Andrea Nakayama, the expert behind the Girl's Guide to Hashimoto's , who cites the importance of fermented foods in managing the disease. It's not all good news when it comes to fermented cod liver oil, and not all of the downsides are linked to the funky taste. Stein is one of many people who remain unconvinced of fermented cod liver oil benefits, especially given recent news stories linked to the product.
The use of salty brine makes the process more similar to pickling rather than fermenting. The biggest concern with fermenting cod liver oil is the rancidity level of the final product. In processing their oil, fermented cod liver oil manufacturers leave the livers in vats exposed to air and sunlight for up to six months 1.
This is problematic on many levels. First of all, the omega-3 molecules oxidize when they are exposed to oxygen. As the molecules oxidize, the oil turns rancid, producing the offensive taste, odor and unpleasant stomach issues that many fermented cod liver oil consumers complain about.
Not only do unappetizing rancid products make it hard for consumers to take sufficient doses of omega-3, rancid oils also contain harmful byproducts that are toxic. When taking any omega-3 product, it is important to be aware of the oxidative status of the oil and to also pay attention to your senses. Truly fresh fish oil and cod liver oil have no fishy taste or smell — just like fresh fish.
Whether you are taking fish oil capsules or a liquid cod liver oil, you can assess the freshness level by tasting and smelling the product. Truly fresh fish oil and cod liver oil has no fishy taste or smell. The second big concern about fermented cod liver oil revolves around the purification of the oil. This is true. Raw cod liver oil does contain potent amounts of vitamin A and D. With most modern processing techniques — like skimming, pasteurizing or ethyl-etherizing the cod liver oil — manufacturers end up destroying much of the vitamin content, as well as the full-spectrum of omega-3s.
However, purifying cod liver oil is important. We use MailChimp as our marketing automation platform.

There are three competing ways to get cod liver oil from cod: you can heat the cod liver, you can extract it using chemical refining, or you can ferment it.
Most commercial cod liver oils are extracted using one of the first two, but manufacturers of fermented cod liver oils claim that their product contains more antioxidants, meaning the fatty acids like omega-3 keep better over time. A team at De Montfort University in Leicester led by Professor Martin Grootveld has tested these claims using a variety of analytical techniques to determine the molecular differences between fermented and unfermented cod liver oils.
They have also pioneered a novel NMR technique to determine the effect of thermal stress on these supplements. For the primitive Norse populations occupying this region during the 8thth centuries, fish liver oils were an important part of their diet to help them through these cold dark months. However, even then they were well acquainted with the health benefits offered by such oils.
These oils were created by allowing livers to settle in barrels for months, and then collecting the released oil. In the late 19th century, Peckel Moller described the development of a liver steaming process to speed its productivity. This is the reason it was later given to children — it could prevent vitamin D deficiencies like rickets.
Nowadays, cod liver oil is generally marketed as a supplement for its omega-3 fatty acid content, which is touted as being beneficial for both brain and heart health.
Lipid oxidation products A little-known issue with these edible oils is that they are particularly susceptible to oxidation, which can be caused by light or prolonged periods of storage, or exposure to heat. This oxidation process is known as lipid peroxidation and generates lipid oxidation product LOP molecules such as aldehydes. LOPs may be toxic to humans if consumed in large amounts.
Without rigorous control to prevent these dangerous molecules forming, such toxins may build-up in edible oil products, especially if stored for long durations, or when heated according to standard frying practices. Fermented cod liver oils But are all cod liver oils created equal? The presence of antioxidants in cod liver oils could, in theory, prevent the oils from oxidising to LOPs.

And, unlike many regular cod liver oil supplements, most fermented cod liver supplements do not list their amounts of vitamin A, D, or EPA and DHA on the label, so there is no way to know exactly how much you are getting.

Related CL Answers 2 What is the difference between fish oil and cod liver oil? Is one better than the other? I am very concerned about getting too much vitamin A. Is there danger in getting too much vitamin A if I take fish oil, which I've heard contains a lot of vitamin A, in addition to my multivitamin?
