Just a note, as someone disputed the effects of Cod Liver Oil. I know several studies have shown positive effects of fish oil on depression and exhaustion associated specifically with Multiple Sclerosis the latest on depression was published by the University of Oregon. I have no comment on the other benefits as I have not personally researched them. 205.188.116.10 21:04, 21 November 2005 (UTC)
OK, this article definitely needs work. It is more or less an advertisement, and contains statement after statement of unverified and very probably false information. Listing it as a candidate for deletion didn't seem all too wrong, but since some company apparently manufactures "cod liver oil", I thought Wikipedia could use a real article on it.
I am aware that the last person to edit this has added a lot of POV, but the earlier editors also couldn't agree on many things, such as why people don't take cod liver oil anymore (and without any references, no-one can know whether anyone has even done so in the first place - I'm certainly not very sure any such thing has ever been normal).
I am skeptical about the claim that historical preparations of CLO were made via fermentation. As far as I can tell, this assertion originated with (and is referenced to) people who make a fermented cod liver oil. Since fermentation in foods means that bacteria / yeast etc act on carbohydrate molecules to make alcohol, using this term to describe an oil extraction seems nonsensical. —Preceding unsigned comment added by 131.191.10.7 (talk) 04:55, 27 August 2010 (UTC)
1.Once commonly given to children daily as a nutritional supplement, it is rarely given today, probably because of ignorance See history for more information.
As a 70 year old man, I can state with certainly that cod liver oil was routinely given to children in the 1940s. It was put into orange juice. (Actually it floated on the top.) It tasted horrible, but it was intended to add vitamin D. At that time vitamin D was not added to milk, as it is now. Rickets was a "real" disease. (George Hardy -- georgeh@ankerstein.org)
2. also helps fight and prevent heart disease, cancer, depression, Alzheimer's, arthritis, diabetes, ulcers, hyperactivity and many other diseases. Increases your energy level and ability to concentrate. Provides greater resistance to common illnesses such as flu and cold. Helps pregnant women avoid premature births, low birth weight and other complications. That's quite a lot of good effects. I don't believe any of that, since I haven't heard of it from other sources. Feel free to prove me wrong.
3. It is wise to supplement your diet with high quality fish or cod liver oils daily, one of the most highly recommened brands is [deleted brand name] which is purified to the highest standards to ensure freedom from detectable levels of mercury, cadmium, lead, PCBs and 28 other contaminants and is free from chemical modification and processing. No advertising on wikipedia please.
4. due too their unnatural diets (ever seen fish swimming through fields of grain!?). So it is best to avoid all farm raised varieties of fish if you value your health. I'm finding it hard to hold back my sarcasm. I can perfectly honestly say that I've read about fish swimming in "fields of grain" during a recent flood. I can't cite the exact issue of the local newspaper though.
5.Meanwhile, our intake of Omega-6, another fat found in corn, soy, sunflower and other oils, is far too high. Once again, this is nothing but speculation, and without references or general encyclopedic standard I'd rather believe the opposite.
I sincerely hope someone with good information sources on something as obscure as cod liver oil could do some research and edit this article to be nicely balanced and encyclopedic. As I mentioned above, I believe wikipedia could use an article on this - I don't have the necessary resources or knowledge to write one myself though.

I believe I have addressed all disputes, and added sufficient references.
GJ, page looks good to me now. We apparently needed another user here to sort it out. ; ) 130.232.120.145 22:08, 5 Mar 2005 (UTC)
I am sorry it was unsigned, Im still new to this wikipedia thing, but i got a username now so it should be ok now.
Anyways I modified the article to clearly explain that those references do indeed apply to both cod liver and fish oils becuase they are so similar and have the same effects to ones health. The saying "probably because of its foul taste" is opinion only, you had no references to back it up. In fact I consume cod liver oil every day and it is not foul at all, only time it is foul is when you let it sit out to rot, otherwise it doesn't have much flavor (neither good nor bad).

The references and information [Oblivion] posted are very informative and relative to the topic. A good edit and a welcome addition to the topic. Madhatter256
Removed reference to fish oil blog .com which is clearly a commercial website.
I'm a little surprised to see somebody question whether codliver oil was really taken as a nutritional supplement in the past. It's a textbook component of childhood horror stories from the old days. This page contains a typical example (1/3 of the way down under "Did rationing affect your life greatly?"): <http://www.wartimememories.co.uk/questions.html>
I would like to hear your reasons for saying that Fish Oil Blog is a commercial site. It does not appear so to me.
The talk page was altered to remove the discussion of fishoilblog. I've reverted the pageblanking. The same IP has removed any mention of the fishoilblog discussion from the Talk pages of Cod liver oil, EPA, DHA and Fish oil. David.Throop 02:41, 20 February 2006 (UTC)
It appears that some of you do not understand the principles of commercial processing of Cod Liver Oils. Indeed the first part of the process involves boiling with steam and pressing to extract the Crude oil. This is not the oil you take in a food supplement or medicinal product. Further processing may involve patented processes for cold clearing (remove stearin), refining (saponification), deodourising, bleaching, ultra-filtration, molecular distillation, etc. These processes actually devitaminise the Oil, thereby removing 'natural' levels of the vitamins you so incorrectly state may be above RDA. The levels of vitamins found in food supplements and medicines containing Cod Liver Oil are strictly controlled in accordance with Food and Medicinal Legislation and based upon Quality, Safety and Efficacy. The processes of manufacture involve doping of the Oil with suitable levels of vitamins to accurately match the label claims on the commercial products (label claimed levels must obviously fall within Safety limits for those vitamins). Cod Liver Oil is licensed as a Medicine in Europe (and many other places around the world) and there is significant evidence to prove its clinical benefit (it wouldn't be a licensed medicine if it didn't have such clinical evidence). In addition, it is sold as a Food Supplement product, where such 'therapeutic' claims are reduced.
Cod Liver Oil is not always found to have a 'fishy' taste or odour. Many modern products have no significant taste or odour and it is commonplace to receive comments from customers that the product must be 'diluted' because it doesn't taste as fishy as it used to. This is simply improved processing and not dilution of the product.
Cod Liver Oil is indeed a good source of vitamins A and D (also vitamin E in some products). The main focus of the product in recent times however, has been upon its fatty acid profile, providing beneficial amounts of Omega-3 polyunsaturated fatty acids. It is widely accepted by Food Safety/Standard Authorities in many 'Western' countries that public diets are significantly unbalanced in terms of Omega-3 and Omega-6 intake. Studies have shown that current intake is 8:1 in favour of the Omega-6 fatty acids, which is something the European Governments are trying to address, as evidence would suggest a 2:1 balance would be better for public health.
Cod Liver Oil and many Cod Liver Oil containing products are widely available in the marketplace and they are being taken by an increasing number of consumers, not a decline. The reason you possibly perceive a decline in consumption is because most Cod Liver Oil products are now branded to focus upon Omega-3 content and are often formulated in conjunction with other 'active' ingredients (e.g. glucosamine, chondroitin, etc.).
Some Omega-3 containing marine-oil based products (Cod Liver Oil and/or Fish Body Oil) are clinicaly proven and licensed medicines for indications such as Joint Care and Heart Health. If you wish to argue with their clinical efficacy in those indications I suggest you take it up with the European Medicines Agencies (e.g. MHRA, IMB, EMEA) as they have approved the Marketing Authorisation Dossiers for such medicinal products.
It puzzles me how people believe that vitamins might have any effect at all on the dead protein-chains of our body hair (vitamin shampoo), but still turn skeptic as soon as it comes to a product that has an unpopular taste. At medical school here in Trondheim at the NTNU cod liver oil is told by professors here to be the only dietary supplement needed in a otherwise balanced diet. The n-3 or n-6 polyunsaturated fatty acids are hard to come over by other means and are useful in combating free radical in the body. For those who understand Norwegian they might be interested in [2] and the Ph.d of Ingrid Helland on Fatty Acids, Mothers & Children Effects of supplementing pregnant and lactating women with n-3 or n-6 polyunsaturated fatty acids. And by the way, for an interesting read on the disadvantages of dietary supplemental vitamins in pill form compared to getting them the "hard" way through vegetables and fruits should read G. Bjelakovic, D. Nikolova, L. L. Gluud, R. G. Simonetti, C.

What you fail to realize is that Wikipedia all too often ends up as a forum/resource for the dogmatic defense of the mainstream. It seems there are plenty of self-appointed arm-chair skeptics objecting to everything that doesn't sound like something Scientific American would publish or endorse. They don't care actually care about truth, but are more interested in following the letter of orthodoxy....
...Thank you for your references though, it's very helpful. Also, I think that this wikipedia entry, as it currently stands (Oct 22nd 2007), is quite good. Well done. —Preceding unsigned comment added by PHDWikiMan (talk • contribs) 21:06, 22 October 2007 (UTC)

does cod liver oil help heal torn ligament in your fingers and do it help with your period —Preceding unsigned comment added by 146.142.28.203 (talk) 13:33, 3 September 2008 (UTC)
This article has some loosely defined terms and possibly pseudoscientific language. It is heavily using scientific jargon and may be doing this to bamboozle. It shows little or no sceptical awareness and so should be treated with caution! Some of the references used point to obviously unscientific websites (healingdaily.com ?)
I've removed the reference to healingdaily.com. Claiming this site as a source of clinical evidence is patently ridiculous. —Preceding unsigned comment added by MonsieurTitus (talk • contribs) 19:15, 26 May 2010 (UTC)
Wow. This article isn't neutral? While perhaps more citations are needed, if this article is up for dispute then Wikipedia has a real problem. There are many reasonably sized and verified studies out there proving the benefits of Omega-3s and Vitamin D --> Fish Oil. It is one of the most common supplements, and certainly accepted by main stream health practioners. If this is up for dispute on Wikipedia, I think I'll get my info from other sources than you very much. — Preceding unsigned comment added by StarBaby5 (talk • contribs) 16:46, 19 December 2011 (UTC)
I'm a nooby at wikipedia, so I hope I'm putting my comments in the right place. The problem with this entry is that the distinction between "fish oil" and "cod liver oil" is not clear. Let's give some attention to the claims made for "fish oil" (mostly based upon the health claims for EPA and DHA), and those that are specific to "cod liver oil", which include those of "fish oil", but tend to emphasize (for better or worse) the vitamin A and D content of cod liver oil.
Any mention of vitamin A or D should be subordinated to the general wikipedia entries for these vitamins. The same is true for any references to the EFA contents of cod liver oil (or any fish oil), or any other nutrient claims.
Wikipedia should strive for overall objectivity, but since this is difficult, internal consistency should be a primary goal. — Preceding unsigned comment added by Dhikr (talk • contribs) 06:04, 28 December 2011 (UTC)
Doesn't this need references? "On the other hand, the RDA of vitamin D is considered by many to be strongly understated. Many adults don't meet the RDA. More research should be conducted in this area." Not quite, but bordering on weasely.
The reference to the SELECT trial does not justify stating as a fact that high intake of fish oils lead to an increased prostate cancer risk. The SELECT trial did not measure dietary parameters at all but relied on a shallow correlation between serum phosphorlipid composition and omega-3 fat intake. Helenuh (talk) 12:16, 13 September 2014 (UTC)
The toxic dose stated, more than 1 kg for a 50 kg person, is a quite amazing dose level. It is more than 100 times the tolerable upper limit. Are both numbers really correct? If so, the toxic dose is irrelevant as nobody eats a kilogram of cod liver oil in a day Helenuh (talk) 12:16, 13 September 2014 (UTC)
I noticed that, too. Do we really need to be warned against drinking 3lbs of oil? I think that the resulting gastric distress will prevent toxicity at that point, anyway. — Preceding unsigned comment added by 69.115.208.61 (talk) 15:41, 9 October 2016 (UTC)
Also, I came here looking for an article on cod liver, a food. Somebody. please? — Preceding unsigned comment added by 69.115.208.61 (talk) 15:44, 9 October 2016 (UTC)
The 'footnote' for Tubingen punting was simply a link to the Wiki article on punting, so I put it in the text and removed the footnote. This simply points out that neither here nor in the Wiki article on punting, where Tubingen is mentioned, is there any source for this information.

Reference was one epidemiological trial reporting that high CLO intake increased risk. In the published literature there is no other support for this result - either no benefit, or benefit. No good reviews on the topic. As ref did not meet MEDRS, deleted. David notMD (talk) 12:43, 26 October 2017 (UTC)
Ref. 3: Rosita Extra-Virgin Cod Liver Oil seems to be connected to a commercial activity selling products. This is not to say, that their information about viking use of cod liver oil and its extraction methods is incorrect, it is just unverifiable. It does not provide any sources for this info and it is not a reliable source itself. so it should not be used as a source by WP. 92.221.117.18 (talk) 16:30, 16 February 2022 (UTC).
