Those participating in style the lawsuit claim that because the liver is the major filtering and detoxifying organ, pcb content may be higher in liver-based oils than in fish oil produced from the processing of whole fish. 67 68 An analysis based on data from the norwegian Women and Cancer Study (nowac) with regards to the dangers of persistent organic pollutants (POPs) in cod liver came to the conclusion that "in Norwegian women, fish liver consumption was not associated with an increased. In contrast, a decreased risk for total cancer was found." 69 A report by the harvard Medical School studied five popular brands of fish oil, including Nordic Ultimate, kirkland and cvs. They found that the brands had "negligible amounts of mercury, suggesting either that mercury is removed during the manufacturing of purified fish oil or that the fish sources used in these commercial preparations oily are relatively mercury-free." 70 Microalgae oil is a vegetarian alternative to fish. Supplements produced from microalgae oil provide a balance of omega-3 fatty acids similar to fish oil, with a lower risk of pollutant exposure. 71 see also edit moghadasian, mohammed.

found an average intake.7 grams of omega-3 epa per day; among other effects these people had prolonged bleeding times,. E., slower blood clotting. 62 Vitamins edit The liver and liver products (such as cod liver oil ) of fish and many animals (such as seals and whales) contain omega-3, but also the active form of vitamin. At high levels, this form of the vitamin can be dangerous ( Hypervitaminosis A ). 63 Toxic pollutants edit consumers of oily fish should be aware of the potential presence of heavy metals and fat-soluble pollutants like pcbs and dioxins, which are known to accumulate up the food chain. After extensive review, researchers from Harvard's School of Public health in the journal of the American Medical Association (2006) reported that the benefits of fish intake generally far outweigh the potential risks. Fish oil supplements came under scrutiny in 2006, when the food Standards Agency in the uk and the food Safety authority of Ireland reported pcb levels that exceeded the european maximum limits in several fish oil brands, 64 65 which required temporary withdrawal of these. To address the concern over contaminated fish oil supplements, the International Fish Oil Standards (ifos) Program, a third-party testing and accreditation program for fish oil products, was created by nutrasource diagnostics Inc. In guelph, Ontario, canada. lawsuit filed by a california environmental group claimed that eight brands of fish oil supplements contained excessive levels of pcb's, including cvs/pharmacy, nature made, rite aid, gnc, solgar, Twinlab, now health, Omega Protein and Pharmavite. The majority of these products were either cod liver or shark liver oils.

The concentration depends on the source of the omega-3s, how the oil is processed, and the amounts of other ingredients included in the supplement. 56 A 2012 report claims 4 of 35 fish oil supplements it covered contained less quantify epa or dha than was claimed on the label, and 3 of 35 contained more quantify 56 A m publication in 2010 claims 3 of 24 fish oil supplements. 48 However, the bioavailability of epa and dha from both capsular and emulsified fish oils has been shown to be high. 57 Formulation edit fish oil supplements are available as liquids or capsules. Some capsules are enteric-coated to pass through the stomach before dissolving in the small vlooien intestine, thus helping prevent indigestion and "fish burps." poorly manufactured enteric-coated products have the potential to release ingredients too early. M, a for-profit supplement testing company, reported that 1 of the 24 enteric-coated fish oil supplements it evaluated released ingredients prematurely. 48 Prescription fish oil edit fish oil preparations that are only available with a doctor's prescription undergo the same fda regulatory requirements as other prescription pharmaceuticals, with regard to both efficacy and safety. 58 Dangers edit a 2013 review concluded that the potential for adverse events amongst older adults taking fish oil "appear mildmoderate at haircut worst and are unlikely to be of clinical significance". 59 Maximum intake edit The fda recommends that consumers do not exceed more than three grams per day of epa and dha combined, with no more than 2 grams from a dietary supplement. 60 This is not the same as 3000 mg of fish oil. A 1000 mg pill typically has only 300 mg of omega-3; 10 such pills would equal 3000 mg of omega-3.

These substances are identified and measured in one of two categories, dioxin-like pcbs and total pcbs. Fda has not set a limit for pcbs in supplements, the Global Organization for epa and dha (goed) has established a guideline allowing for no more than 3 picograms of dioxin-like pcbs per gram of fish oil. In 2012, samples from 35 fish oil supplements were tested for pcbs. Trace amounts of pcbs were found in all samples, and two samples exceeded the goeds limit. 56 Although trace amounts of pcbs contribute to overall pcb exposure, m claims the amounts reported by tests it ordered on fish oil supplements are far below those found in a single typical serving of fish. 56 Spoilage edit peroxides can be produced when fish oil spoils. A study commissioned by the government of Norway concluded there would be some health concern related to the regular consumption of oxidized (rancid) fish/marine oils, particularly in regards to the gastrointestinal tract, but there is not enough data to determine the risk. The amount of spoilage and contamination in a supplement depends on the raw materials and processes of extraction, refining, concentration, encapsulation, storage and transportation. 51 m reports in its review that it found spoilage in test reports it ordered on some fish oil supplement products. 56 epa and dha content edit According to independent laboratory which? tests, the concentrations of epa and dha in supplements can vary from between 8 and 80 fish oil content.

47 Supplement quality and concerns edit fish oil is a commonly used dietary supplement, with sales in the. Alone reaching 976 million in 2009. 48 Problems of quality have been identified in periodic tests by independent researchers of marketed supplements containing fish oil and other marine oils. These problems include contamination, inaccurate listing of epa and dha levels, spoilage and formulation issues. 49 Contamination edit fish can accumulate toxins such as mercury, dioxins, and polychlorinated biphenyls (PCBs and spoiled fish oil may produce peroxides. 50 There appears to be little risk of contamination by microorganisms, proteins, lysophospholipids, cholesterol, and trans-fats. 51 Mercury edit research by the. Food and Drug Administration concluded that one serving of multiple food fishes contains an average.121 parts per billion ( ppb ) of mercury. 52 This is equal.09 of the tolerable weekly intake (TWI) for methylmercury,.08 of the twi for inorganic mercury. 53 Comparatively, using ppb and micrograms ( μg ) interchangeably in a similar aqueous density, 54 servings of fish oil supplements (multiple brands included in study) were found to contain an average.4 ppb of mercury and as high as 10 ppb of mercury. The average was equal.85 of the twi and the high value equal.69 times the twi for methylmercury; also expressible as an average.60 of the twi and up.5 times the twi for inorganic mercury. 55 53 dioxins and pcbs edit dioxins and pcbs may be carcinogenic at low levels of exposure over time.

meta-analysis of PubMed articles about fish oil and depression from 1965 to 2010, researchers found that "nearly all of the verliefd treatment efficacy observed in the published literature may be attributable to publication bias." 41 A 2014 meta-analysis of eleven trials conducted respectively on patients with. The study concluded that: "The use of omega-3 pufa is effective in patients with diagnosis of mdd and on depressive patients without diagnosis of mdd." 42 Alzheimer's disease edit a cochrane meta-analysis published in June 2012 found no significant protective effect for cognitive decline for. A co-author of the study said to time, "Our analysis suggests that there is currently no evidence that omega-3 fatty acid supplements provide a benefit for memory or concentration in later life". 43 Psoriasis edit diets supplemented with cod liver oil have shown beneficial effects on psoriasis. 44 Pregnancy edit some studies reported better psychomotor development at 30 months of age in infants whose mothers received fish oil supplements for the first four months of lactation. 45 In addition, five-year-old children whose mothers received modest algae based docosahexaenoic acid supplementation for the first 4 months of breastfeeding performed better on a test of sustained attention. This suggests that docosahexaenoic acid intake during early infancy confers long-term benefits on specific aspects of neurodevelopment. 45 In addition, provision of fish oil during pregnancy may reduce an infants sensitization to common food allergens and reduce the prevalence and severity of certain skin diseases in the first year of life. This effect may persist until adolescence with a reduction in prevalence and/or severity of eczema, hay fever and asthma. 46 Crohn's disease edit a 2014 Cochrane review found that, based on two large studies, fish oil supplements did not appear to be effective for maintenance of remission in Crohn's disease. omega 3 oil fish

33 34 However, a 2012 meta-analysis found no such significant benefit. 35 A 2008 meta-study by the canadian Medical Association journal found fish oil supplementation did not demonstrate any preventative benefit to cardiac patients with ventricular arrhythmias. 36 A 2012 meta-analysis published in the journal of the American Medical Association, covering 20 studies and 68,680 patients, found that carré Omega-3 Fatty Acid supplementation did not reduce the chance of death, cardiac death, heart attack or stroke. 37 Hypertension edit There have been kind some human trials that have concluded that consuming omega-3 fatty acids slightly reduces blood pressure (dha could be more effective than epa). It is important to note that because omega-3 fatty acids can increase the risk of bleeding, a qualified healthcare provider should be consulted before supplementing with fish oil. 38 Mental health edit a 2008 Cochrane systematic review found that limited data is available. In the one eligible study, omega-3s were an effective adjunctive therapy for depressed but not manic symptoms in bipolar disorder. The authors found an "acute need" for more randomised controlled trials. 39 A 2009 metastudy found that patients taking omega-3 supplements with a higher epa:dha ratio experienced fewer depressive symptoms. The studies provided evidence that epa may be more efficacious than dha in treating depression. However, this metastudy concluded that due to the identified limitations of the included studies, larger, randomized trials are needed to confirm these findings.

The us national Institutes of health lists three conditions for which fish oil and other omega-3 sources are most highly recommended: hypertriglyceridemia (high triglyceride level preventing secondary cardiovascular disease, and hypertension (high blood pressure). It then lists 27 other conditions for which there is less evidence. It also lists possible safety concerns: "Intake of 3 grams per day or greater of omega-3 fatty acids may increase the risk of bleeding, although there is little evidence of significant bleeding risk at lower doses. Very large intakes of fish oil/omega-3 fatty acids may increase the risk of hemorrhagic (bleeding) stroke." 12 There is also some evidence that fish oil may have a beneficial effect on certain abnormal heart rhythms.

15 The various species range from lean to fatty and their oil best content in the tissues has been shown to vary from.7.5. 16 They also differ in their effects on organ lipids. 15 Studies have revealed that there is no relation between total fish intake or estimated omega3 fatty acid intake from all fish, and serum omega3 fatty acid concentrations. 17 Only fatty fish intake, particularly salmonid, and estimated epa dha intake from fatty fish has been observed to be significantly associated with increase in serum epa dha. 17 Contents Often marketed and sold for consumption as part of the diet or in dietary supplements in contemporary societies, fish oils also have found roles in external use, as emollients 18 or as general ointments 19 as well as in body art,. 21 Nutritional details edit The most widely available dietary source of epa and dha is cold-water oily fish, such as salmon, herring, mackerel, anchovies, and sardines. Oils from these fish have a profile of around seven times as much omega-3 oils as omega-6 oils. Other oily fish, such as tuna, also contain omega-3 in somewhat lesser amounts.

Fish oil - wikipedia

Fish oil capsules, fish oil is oil derived from the tissues of oily fish. Fish oils contain the omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (dha precursors of certain eicosanoids that are known to reduce inflammation in the body, 1 2 and have other health benefits, such as treating hypertriglyceridemia, although claims of preventing heart attacks. 3 4 5 6, fish oil and omega-3 fatty acids have been studied in a wide variety of other conditions, such as clinical depression, 7 8 anxiety, 9 10 11 cancer, and macular degeneration, yet benefits in these conditions have not been verified. 12, the fish used as sources do not actually produce omega-3 fatty acids, but instead accumulate them by consuming either microalgae or prey fish that have accumulated omega-3 fatty acids. Fatty predatory fish like sharks, swordfish, tilefish, and albacore tuna may be high in omega-3 fatty acids, but due to their position at the top of the food chain, these species may also accumulate toxic substances through biomagnification. For this reason, the United States Environmental Protection Agency recommends limiting consumption (especially for women of childbearing age) of certain (predatory) fish species (e.g. Albacore tuna, shark, king mackerel, tilefish and swordfish ) due to high levels of the toxic contaminant mercury. Dioxin, pcbs and chlordane are also present. 13 Fish oil is used as a component in aquaculture feed. More than 50 percent of the world's fish oil used in aquaculture feed is fed to farmed salmon. 14 Marine and freshwater fish oil vary in contents of arachidonic acid, epa and dha.
