Side Effects Of Fish Oil
Side effects of fish oil include heartburn, diarrhea as well as fish breath odour and fish aftertaste, which many patients find to be unpleasant.11 Some methods to avoid the fish aftertaste include adding citrus or peppermint flavour to fish oil, taking fish oil in a small glass of fruit or vegetable juice or having fish oil immediately before meals.5,11
Cod liver oil contains vitamin A at levels higher than the recommended amounts at the dosage needed to produce an anti-inflammatory response. According to some studies, cod liver oil at that dosage may be linked to elevated risk of hip fracture and decreased bone density.11
Talk to your doctor about your medical condition and seek medical advice on whether you can take fish oil with your medications or medical conditions.
Possible Side Effects Of Fish Oil
Side effects of fish oil supplementation are generally mild, such as fishy-tasting burps, upset stomach, and mild diarrhea.1 If you are experiencing these side effects, try taking smaller doses throughout the day, and be sure to consume the pill with food to increase absorption.
Fish oil supplements may interfere with blood clotting and increase the risk for stroke, particularly if they are taken in combination with aspirin or other non-steroidal anti-inflammatory drugs .1 Talk to your doctor about all your medications and supplements before starting on fish oil supplements.
Should You Take Fish Oil
Despite the popularity of fish oil supplements for arthritis, researchers say there is insufficient evidence at this point to promote their use solely for the purpose of osteoarthritis treatment. Possible efficacy in laboratory and animal studies has yet to be sufficiently observed and verified in clinical trials, write the authors of the 2015 review in the American Journal of Orthopaedics. At the same time, the authors say it is impossible to refute the benefits of fish oil as an adjunct to anti-inflammatory therapy.
In short, while the evidence is not great enough to promote fish oil as an OA therapy just yet, if you are taking fish oil to reduce inflammation for rheumatoid arthritis or cardiovascular health, for example the supplements could potentially provide the added benefit of protecting your joints from cartilage breakdown or reducing its severity.

What Kinds Of Omega
The two most important members of the omega-3 family are called eicosapentaenoic acid and docosahexaenoic acid , which are mainly found in oily fish and fish oil.
EPA and DHA arent the only types of omega-3 fatty acids that exist. However, they are considered to be the most potent. Thats why almost all omega-3 research in the last 50 years has focused on the health benefits of EPA and/or DHA specifically.
Theres less research about the effects of the plant-based omega-3 ALA thats found in walnuts, flaxseed, and chia seeds. While our bodies have enzymes that convert plant-based ALA into EPA , this conversion rate is negligible . For that reason, the strength of an omega-3 supplement is typically only measured by the amount of EPA and DHA it contains.
Not all omega-3 sources are equal: Plant-based omega-3 sources, like flaxseed and chia seeds, do not contain any EPA or DHA.
Effect Of Fish Oil On Body Weight
Fish oil, like any fat, is rich in calories. However, most people eat to satiety. In our Early Arthritis Clinic, a cohort of 33 RA patients taking fish oil at the rate of 15 ml/day immediately before or during a meal did not increase their mean weight over 1 year there was a nonsignificant mean change of -0.4 kg from baseline to 1 year. Metabolic studies suggest the LC n3 PUFAs present in fish oil can reduce adipocyte numbers and the contribution of adipose tissue to body mass .

Whats The Evidence Behind Omega
Omega-3 fatty acid supplements for RA have been widely studied. Fish oil, in particular, has been shown to reduce joint pain, as well as the stiffness you might feel when you wake up after a nightâs sleep. Other studies have suggested these supplements may help people with RA get by with lower doses of nonsteroidal anti-inflammatory drugs . Thatâs important, since NSAIDs can cause many side effects if you take them too long. But fish oil doesnât seem to slow progression of the RA itself. It just helps to relieve symptoms.
Of course, supplements arenât the only source of omega-3s. Diets rich in these fatty acids may also prove useful. More research is needed about that, though.
Natural Sources Of Omega 3s
EPA and DHA can be found naturally in salmon, sardines, and anchovies, and your dog will probably find this to be a tasty treat!
In a 6 oz serving, this is how much Omega 3s your dog would get from each source:
- Anchovies, 3400 mg of EPA/DHA
- Sardines, 2800 mg of EPA/DHA
- Salmon, between 2200- 3800 mg of EPA/DHA
- NOTE: CARE does not recommend using salmon or salmon oil as a daily source of Omega 3s in dogs as it is not the most environmentally sustainable source.

Natural fish oils contain a cocktail of beneficial fatty acids and nutrient cofactors that work together to support our health. Unfortunately, many omega-3 products are stripped of this rich fatty acid content through winterization and/or concentration.
Just like drinking filtered orange juice is not as healthy as eating a fresh orange, the more an omega-3 oil is processed, the less potent and bioavailable it becomes . This is why its important to look for omega-3 products that are non-winterized and contain a broader range of fatty acids than just EPA or DHA.
Safe Limits Of Long Chain N3 Polyunsaturated Fatty Acid Ingestion
A dose of 3 g/day EPA plus DHA has been assessed as safe for general consumption . Greenland Inuits consuming their aboriginal diet of sea mammals, sea birds and fish ingest 7 g/day LC n3 PUFAs . These Inuits appear to have a bleeding tendency, which may contribute to an observed increase in apoplexy . The very high consumption of LC n3 PUFAs in this population occurs within the context of a low n6 PUFA intake. The equivalence of AA and EPA in Inuit platelet cell membranes was not reached closely by Australian patients taking 4.5 g fish oil for RA for more than 3 years, although this ratio is substantially different from that in healthy Australian control individuals not taking fish oil and consuming an ordinary diet . The Inuits have a very low frequency of myocardial infarction , which appears to be due in major part to dietary PUFAs . They also have a low frequency of inflammatory diseases. For patients with a chronic inflammatory disease such as RA, which is associated with high cardiovascular risk , the reduced cardiovascular risk with and anti-inflammatory effect of fish oil is likely to yield an overall long-term advantage. The disease-modifying effect of fish oil in RA, positive or negative, is unknown. However, the inhibitory effect of anti-inflammatory doses of fish oil on TNF and interleukin-1 synthesis provides the potential basis for a favourable long-term effect on disease progression.

Where Else Can I Find Omega 3s
There are many Omega 3 supplements available today. Most products will list the amount of EPA, DHA, and total Omega 3s. The total number will be larger than the sum of EPA and DHA due to other Omega 3s.
The ideal dose should be the total of EPA + DHA, not necessarily the total Omega 3 content. However, it is OK to determine what dose to give your dog using the total Omega 3 content listed on the supplement package.
The Benefits Of Omega
Youve probably heard of omega-3 fatty acids, especially if you have an inflammatory type of arthritis. They help reduce inflammation throughout the body, and some studies have shown benefits for heart health, brain function and diabetes.
There are two major types of omega-3 fatty acids in our diets. One type is alpha-linolenic acid and the other type is eicosapentaenoic acid and docosahexaenoic acid . The body partially converts ALA to EPA and DHA.
According to the National Institutes of Health , fish oil is the most commonly used dietary supplement in the United States. A study published in the Annals of Rheumatic Disease in 2013, found that when a high-dose fish oil supplement is added to so-called triple therapy for rheumatoid arthritis , patients achieved better outcomes: they were far less likely to fail treatment and twice as likely to reach remission than those who did not take a supplement.
According to the results of at least 13 studies involving more than 500 participants, people with rheumatoid arthritis who took omega-3s supplements had a reduction in joint pain but not in joint damage. Other studies suggest that omega-3s may help RA patients lower their dose of nonsteroidal anti-inflammatory drugs . And according to information from NIH, administering fish oil by IV reduces swollen and tender joints in people with RA.
Here are some others ways that omega-3s can boost your health, according to researchers.
Availability And Merits Of Different Fish Oils
Oils derived from marine fish oil all contain LC n3 PUFAs. Standard fish oil is extracted from fish bodies and typically contains EPA 18% and DHA 12% w/w. Until recently, this was available only in capsules, but now a bottled preparation is available in Australia. Cod liver oil is widely available as both bottled oil and in capsules. It contains approximately 10% EPA and 10% DHA, and so it is also a good source of LC n3 PUFAs. However, at anti-inflammatory doses cod liver oils, which are rich in the fat-soluble vitamins A and D, contain more vitamin A than recommended intakes. Although the amount does not cause symptoms of toxicity, similar doses have been associated with reduced bone density and increased risk for hip fracture in epidemiological studies . This is not a problem with fish body oils, which contain very little of these fat-soluble vitamins.
Is It Better Than Other Omega
Fish oil supplements supply EPA and DHA and many also have vitamins A and D.
Meanwhile, general omega-3 supplements may or may not contain EPA and DHA, depending on whether they are derived from fish, sea algae or plant oils.
If your omega-3 supplement is made from sea algae, it has EPA and DHA. Usually, these supplements are high in DHA and low in EPA .
On the other hand, fish oil supplements likely have higher amounts of EPA than DHA, while plant-oil-based supplements give high amounts of ALA.
Although all omega-3s provide benefits, the most beneficial are EPA and DHA .
If you do not eat fatty fish regularly, a fish oil supplement may boost your EPA and DHA levels. However, if you dont consume any fish products, an algae-based supplement is a good alternative.
Otherwise, an omega-3 supplement made from plant oils will help increase your overall intake of omega-3s but likely wont raise your EPA or DHA levels.
Not all omega-3s are equal. While fish oil supplements provide EPA and DHA, most plant sources of omega-3 give ALA which can be difficult to convert into EPA and DHA.

Dietary Sources Of N3 And N6 Polyunsaturated Fatty Acids
In seeking to alter the balance of n3 and n6 PUFAs in the tissues with therapeutic intent, it is necessary to understand which foods are rich in these fatty acids. This allows n3-rich items to be selected and n6-rich items to be avoided. In addition to fish oils, n3 PUFAs are found in the flesh of all marine fish, including crustaceans and shellfish. In fish and fish oils, n3 PUFAs are present as long chain PUFAs PUFAs. In certain vegetable oils, notably flaxseed, perilla and, to a lesser extent, canola oil, n3 PUFAs are present as the C18 PUFA -linolenic acid . In sunflower, cottonseed, safflower and soy oils, and the spreads manufactured from them, the main fatty acid is the n6 C18 PUFA linoleic acid . Olive oil and canola oil are rich sources of oleic acid , which is a monounsaturated fatty acid containing a single double bond in the n9 position. Oleic acid can be endogenously synthesized by humans, and so it is not an essential fatty acid .

Reduced Joint Pain Isnt The Only Benefit Of Fish Oil
While fish oil supplements are strongly recommended for many people with rheumatoid arthritis, the supplement can improve other areas of health as well. Research has shown that omega-3s can improve immune function, lower blood pressure, and improve heart disease symptoms.Many patients with arthritis also have other health conditions. Nearly half of all adults with heart disease also suffer from some form of arthritis. For many people, a fish oil supplement can offer a huge bang for the buck in improving health.
How Much Epa And Dha Is In Regular Fish Oil Supplements
Fish oil capsules often advertise that they provide 1000 mg of fish oil, which sounds like a big dose. That is until you realize that fish oil is only partially made up of omega-3s.
Natural fish oils contain a maximum of 30% EPA and DHA combined. With a regular 1000 mg fish oil capsule, that means youre only getting 300 mg of EPA and DHA per gel cap. Non-concentrated krill oil capsules contain even lower percentages of omega-3s.
Concentrated omega-3 products contain higher levels of EPA and DHA per serving. But even with concentrated capsules, youd typically have to swallow a small handful of pills to get a meaningful amount of EPA and DHA per day.
Where Tofind Fish Oil
Picking up a bottle of fish oil from any major grocery store or supplement center is a common way many people incorporate this omega-3 fatty acid into their diet. Aside from oral supplements, fish oil can be obtained through eating fresh fish from your local supermarket. To reap the full benefits provides, lean toward cold water fish options, such as salmon, sardines and anchovies.
If youre experiencing severe joint pain or arthritis that has resulted in long-term pain, this supplement might not be the best remedy for your situation. For those who have mild joint pain, this supplement could be just what you need to experience joint relief and get back to your normal routine.
Its important to consult your physician before adding a new supplement to your daily regimen. Make an appointment at Campbell Clinic to see if fish oil supplements are a safe option for your joint pain.

Technique For Taking Bottled Fish Oil
Fish oil has a taste and odour that most people find unpleasant, and for this reason it has been largely distributed within capsules. However, the taste of fish oil can be masked partially with flavouring . The taste can be avoided more completely by taking fish oil on juice using a method that avoids contact of fish oil with the lips where the fish oil taste is experienced.
Layer the desired dose of fish oil onto the juice in one glass do not stir.
Swallow the juice and fish oil with a single gulp, avoiding contact with the lips .
Immediately sip the juice in the other glass slowly through the lips. This will remove any oil from the lips.
Take the fish oil immediately before a solid meal and without further fluid. This avoids floating of the oil on fluid in the stomach and favours mixing of the fish oil with food and passage from the stomach into the intestine. If reflux becomes a problem, then split the dose before morning and evening meals. Alternatively, take the dose then lie on the left side for at least 15 min. In this position the oil floats into the passage from the stomach to the small intestine.
Fish oil is preferable to cod liver oil, which can deliver undesirable amounts of vitamin A at anti-inflammatory doses.
Fasting Diet For Rheumatoid Arthritis
Intermittent fasting which involves eating and fasting on a regular schedule, has become popular recently.
Both the safety and the efficacy of committing to periods of fasting are in question.
Some small studies have shown that restricting calories, as happens during a typical IF diet, may have an anti-inflammatory effect. The exact mechanisms by which this occurs are unknown.
One study in people with rheumatoid arthritis took place during Ramadan, a holiday when religious Muslims fast for 30 days from dawn to dusk .
Do not fast or get your nutrition from juice alone without consulting a physician first.

Why And How Should You Take Fish Oil
ââThe American Heart Association endorses omega-3 fatty acids as a regular part of your diet. They recommend two servings of fatty fish per week to reduce the risk of stroke and heart disease.
Supplements. Your body can’t create these essential fatty acids naturally. Supplements and omega-3 rich foods are the only way to get them.
Lifestyle changes. To get the greatest benefits from taking fish oil supplements, combine them with lifestyle changes. Weight loss, regular exercise, and improving your diet will further reduce your risk of stroke and heart disease. Avoiding refined carbohydrates and processed sugar in addition to choosing plant-based fats will also help.
Medications. For older adults, there are even more considerations beyond the cardiovascular link. Omega-3 may also help lower your bad cholesterol, or triglyceride, levels. The Food and Drug Administration has also approved prescription-only omega-3 medications. These are specifically for individuals whose triglyceride levels are higher than 500 mg/dL.
Just 4 grams of this prescription omega-3 per day can help most people lower their triglyceride levels by as much as 30%. Consult your doctor if you have other conditions such as hypothyroidism or Type 2 diabetes. These may cause your triglyceride levels to increase.
