"All these diseases have a common genesis in inflammation," says Joseph C. Maroon, MD, professor and vice chairman of the department of neurological surgery at the University of Pittsburgh School of Medicine. Co-author of Fish Oil: The Natural Anti-Inflammatory, Maroon says that in large enough amountsomega-3's reduce the inflammatory process that leads to many chronic conditions.

Oil was also used externally as an ointment to heal cold sores, cuts, insect bites, frostbite, rashes - in short, skin problems of all kinds. Duck or goose body-cavity fat was apparently as useful as seal or fish oil in dealing with skin problems.
After the age of five, the development of the brain and CNS starts to reduce and the body’s need for DHA reduces. This is a good time to increase EPA in the diet, as studies show that EPA can help with childhood behaviour and academic performance, as well as focus, attention and reducing aggression. Dry skin conditions, asthma and allergies are also common in children and good levels of EPA at this time can help reduce the inflammation associated with these issues.
Omega-3 fatty acids, which are found abundantly in fish oil, are increasingly being used in the management of cardiovascular disease. It is clear that fish oil, in clinically used doses (typically 4 g/d of eicosapentaenoic acid and docosahexaenoic acid) reduce high triglycerides. However, the role of omega-3 fatty acids in reducing mortality, sudden death, arrhythmias, myocardial infarction, and heart failure has not yet been established. This review will focus on the current clinical uses of fish oil and provide an update on their effects on triglycerides, coronary artery disease, heart failure, and arrhythmia. We will explore the dietary sources of fish oil as compared with drug therapy, and discuss the use of fish oil products in combination with other commonly used lipid-lowering agents. We will examine the underlying mechanism of fish oil’s action on triglyceride reduction, plaque stability, and effect in diabetes, and review the newly discovered anti-inflammatory effects of fish oil. Finally, we will examine the limitations of current data and suggest recommendations for fish oil use.

Additional side effects of fish oil supplements which have been reported include headache, short-term memory loss, depression, somatic disorders, and increased risk of colon cancer, nasopharyngitis, worsening of asthma symptoms, hemolytic anemia, decreased physical activity, increased appetite, a general uncomfortable feeling or increased blood pressure. The percentage of users that develop these side effects is not known. If these side effects become severe it is recommended that you stop using fish oil supplements.
To improve the health of your heart, brain, skin, hair, body and much, much more, consider adding fish oil to your daily supplement regime or consume wild-caught fish daily. If you’re adverse to fish oil pills, make sure to get at least two servings of fatty fish each week to fulfill your omega-3 needs and provide your body with fish oil benefits. This is a recommendation also encouraged by the American Heart Association. (38)
Recently another Omega-3 fatty acid, DPA (Docosapentaenoic Acid) has been discussed more frequently in the scientific community, as a new and very potent Omega-3 fatty acid. Previously thought to work in through EPA and DHA we are now learning it has very distinct functions in the body. All three of these polyunsaturated fats play an important role in the functioning of our bodies.
According to the National Psoriasis Foundation, fish oil can aid in preventing or slowing heart disease, which is especially great for psoriasis and psoriatic arthritis sufferers who are at a higher risk of developing heart disease. (27) When it comes to using fish oil supplements for the alleviation of psoriasis symptoms, studies have been mixed with some showing improvement but others showing no effect. If you suffer from psoriasis, you may want to try a fish oil supplement, or else I highly recommend that you make sure to have fish rich in omega-3s regularly.

Animal studies show potent reduction of liver fat stores, glucose levels, and cholesterol levels in mice supplemented with krill oil while being fed a high fat diet.64,65 While many of these effects are seen with fish oil as well, studies show that krill oil, with its unique phospholipid structure, had the added benefit of increasing fat-burning in mitochondria while reducing new glucose production in the liver.66,67 As with so many other complex disease processes, utilizing multiple pathways to reduce disease is a highly effective strategy.67
The nutritional value of seafood is important during early development. The Dietary Guidelines for Americans 2015–2020 and guidance from the U.S. Food and Drug Administration and Environmental Protection Agency recommend that women who are pregnant or breastfeeding eat at least 8 ounces but no more than 12 ounces of a variety of seafood each week, from choices that are lower in methyl mercury. Methyl mercury can be harmful to the brain and nervous system if a person is exposed to too much of it. 
An excessive dosage of fish oil can have adverse allergies and side effects on the body. Furthermore, fish oil can be problematic if you have certain conditions so it is necessary to consume fish oil supplements cautiously. Moreover, it can be consumed in various forms. These include eating the fish directly by baking, roasting, frying, grilling, broiling, or smoking it. It can also be consumed in the form of concentrated dietary supplements like liquid, tablet, capsule, pill, or soft gels. Also, there are various pharmaceutical grades of the oil. It is not necessary to constantly consume pharmaceutical-grade oil or even supplements. You should also consult your doctor to confirm the mode of consuming fish oil and the overall need for it in your diet.
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.[40]

Before getting to know some of the fish oil side effects, you have to know more about fish oil, like its benefits and usages. Fish oil has become a popular supplement for athletes, as well as those looking to improve their overall health. Many claims have been made regarding the improvements to the body which can be made by using fish oil to increase the body's level of fatty omega-3 acids. Some of these claims have been backed up by studies, while others have not been proven with significant scientific evidence. There are also some precautions that need to be addressed if you will be taking fish oil regularly. People with certain health conditions may see a worsening of their symptoms if they increase their intake of fatty acids too quickly or with the wrong products.
The biggest cause of omega-3 deficiency is the overconsumption of foods high in omega-6 fatty acids. Omega-6 comes from things like fried foods, fast foods and boxed foods that contain vegetables oils like soybean oil, canola oil, sunflower oil, cottonseed oil and corn oil. When you consume too much omega-6, it can decrease your body’s ability to metabolize healthy omega-3 fatty acids. (36)
Soy can get a bad rap — and may indeed cause problems for people with certain food sensitivities — but this delicious bean is one of the most powerful (and versatile) ways to add omega-3 to your diet. Whole soybeans (known as edamame) are a favorite protein-packed snack for vegetarians; more processed forms (including tofu, soy milk, and soybean-based cooking oil) make soy infinitely more accessible. For some ideas, check out the 1998 classic, The Whole Soy Cookbook, which outlines how to cook with soy-based products ranging from miso to tempeh and beyond.
A study published in Brain Research shows how far-reaching fish oil can be for people with diabetes. Researches found that fish oil can help reduce the risk of diabetics from developing cognitive deficit because it protects the hippocampus cells from being destroyed. The study also showed that fish oil could help reduce oxidative stress, which plays a central role in the development of diabetes complications, both microvascular and cardiovascular. (22)
The competition between EPA and DHA during digestion and absorption and the fact that DHA appears to ‘block’ the therapeutic actions of EPA can therefore be an issue if we are looking to optimise the benefits associated with EPA (Martins 2009; Bloch & Qawasmi et al, 2011; Sublette et al, 2011). High dose, high concentration and high ratio EPA supplements increase the effectiveness in depression studies, and pure EPA-only is optimal. Depression is also a condition with an inflammatory basis, so this is likely another significant reason for EPA being the key player – its antagonistic relationship with the inflammatory omega-3 AA (arachidonic acid) is very effective at reducing inflammation.

Your concerns are very valid. The quality of commercially available omega-3 preparations can vary greatly. In our clinical trials we use preparations made by reputable manufacturers with high standards. We also have the preparations analyzed by 2 independent labs to confirm omega-3 content, impurities, and degree of oxidation, prior to initiating the study. While omega-3 fatty acids–like most nutrients–are ideally obtained through dietary practice, because many people may not enjoy omega-3 containing foods, supplements may be a good option for these individuals. Anyone who is interested in using an omega-3 preparation for treating a psychiatric condition should do so preferably under the supervision of a psychiatrist.

This systematic review and meta-analysis of clinical trials conducted on participants with clinical anxiety symptoms provides the first meta-analytic evidence, to our knowledge, that omega-3 PUFA treatment may be associated with anxiety reduction, which might not only be due to a potential placebo effect, but also from some associations of treatment with reduced anxiety symptoms. The beneficial anxiolytic effects of omega-3 PUFAs might be stronger in participants with specific clinical diagnoses than in those without specific clinical conditions. Larger and well-designed clinical trials should be performed with high-dose omega-3 PUFAs, provided as monotherapy and as adjunctive treatment to standard therapy.

Respected health care organizations proposed intake recommendations for oily fish of two servings per week for healthy adults, which equates to approximately a daily total of 500 milligrams (mg) EPA and DHA.‡ The recommendation encourages adults already with or at-risk of developing cardiovascular disease to talk to their primary healthcare professional about supplementing with amounts greater than 500 mg of EPA and DHA per day. Supportive but not conclusive research shows that consumption of EPA and DHA omega-3 fatty acids may reduce the risk of coronary heart disease.

In some cases, fish oil pills may cause loose stools, nausea, diarrhea, and decreased appetite, fat in the stools, vomiting or constipation. These side effects can be minimized by taking a fish oil capsule that is coated, which is designed to help eliminate the "fish burps" many users complain about. Starting with low doses of the supplement and working up to a full dose can also help minimize side effects. You can also pair fish oil supplements with meals so that they enter your body more slowly, minimizing the risk of side effects occurring.
We’ve already seen that fish oil can help with depression-like symptoms in rats, but what about people? A study published in the journal Nutritional Neuroscience evaluated the effects of fish oil supplementation on prefrontal metabolite concentrations in adolescents with major depressive disorder. Researchers found that there was a 40 percent decrease in major depression disorder symptoms in addition to marked improvements in amino acid and nutrition content in the brain, specifically, the right dorsolateral prefrontal cortex. (21)
The effect of fish oil consumption on prostate cancer is controversial,[28][29] as one study showed decreased risk with higher blood levels of DPA, whereas another reported increased risk of more aggressive prostate cancer with higher blood levels of combined EPA and DHA.[30] Some evidence indicated an association between high blood levels of omega-3 fatty acids and an increased prostate cancer risk.[31]

Pregnancy and breast-feeding: Fish oil is LIKELY SAFE when taken by mouth appropriately. Taking fish oil during pregnancy does not seem to affect the fetus or baby while breast-feeding. Women who are pregnant or who may become pregnant, and nursing mothers should avoid shark, swordfish, king mackerel, and tilefish (also called golden bass or golden snapper), as these may contain high levels of mercury. Limit consumption of other fish to 12 ounces/week (about 3 to 4 servings/week). Fish oil is POSSIBLY UNSAFE when dietary sources are consumed in large amounts. Fatty fish contain toxins such as mercury.
