Omega-3 are considered essential fatty acids: They are necessary for human health but the body can’ t make them — you have to get them through food. These fats can be found in fish, such as salmon, tuna, and halibut, other seafood including algae and krill, some plants, and nut oils.
Also known as polyunsaturated fatty acids (PUFAs), they play a crucial role in brain function as well as normal growth and development. They have also become popular because they may reduce the risk of heart disease.
Like this “Iceberg” shows, the diseases, so visible on our “outside”, such as diabetes, cancer, or fibromyalgia, high blood pressure have a root cause. That root cause is often “inflammation”. Omega 3 FIGHTS INFLAMMATION!
The American Heart Association recommends eating fish (particularly fatty fish such as mackerel, lake trout, herring, sardines, albacore tuna, and salmon) at least 2 times a week.

Research shows that fish oil EPA and DHA reduce inflammation and may help lower risk of chronic diseases such as heart disease, cancer, and arthritis. Omega3 fats are highly concentrated in the brain and appear to be important for cognitive (brain memory and performance) and behavioral function. In fact, infants who do not get enough from their mothers during pregnancy are at risk for developing vision and nerve problems. Symptoms of of deficiency include fatigue, poor memory, dry skin, heart problems, mood swings or depression, and poor circulation.
is important to have a balance of omega-3 and omega-6 (another essential fatty acid) in the diet. These help reduce inflammation, and most omega-6’s tend to promote inflammation. The typical American diet tends to contain 14 – 25 times more omega-6 than omega-3.
Clinical evidence is strongest for heart disease and problems that contribute to heart disease, but fish oils may also be used for: LET OMEGA 3 HELP FIX YOUR BROKEN HEART
People who follow a Mediterranean-style diet tend to have higher HDL or “good” cholesterol levels, which help promote heart health. Inuit Eskimos, who get high amounts of omega-3 fats from eating fatty fish, also tend to have increased HDL cholesterol and decreased triglycerides (fats in the blood). Several studies have shown that fish oil supplements reduce triglyceride levels. Finally, walnuts (which are rich in alpha linolenic acid or LNA, a type of omega-3 fatty acid) have been reported to lower total cholesterol and triglycerides in people with high cholesterol levels.
High blood pressure
Several clinical studies suggest that diets or fish oil supplements rich in omega-3 fatty acids lower blood pressure in people with hypertension. An analysis of 17 clinical studies using fish oil supplements found that taking 3 or more grams of fish oil daily may reduce blood pressure in people with untreated hypertension.
One of the best ways to help prevent heart disease is to eat a diet low in saturated fat and to eat foods that are rich in monounsaturated and polyunsaturated fats (including omega-3). Clinical evidence suggests that EPA and DHA (eicosapentaenoic acid and docosahexaenoic acid, the two omega-3 fatty acids found in fish oil) help reduce risk factors for heart disease, including high cholesterol and high blood pressure. Fish oil has been shown to lower levels of triglycerides (fats in the blood), and to lower risk of death, heart attack, stroke, and abnormal heart rhythms in people who have already had a heart attack. Fish oil also appears to help prevent and treat atherosclerosis (hardening of the arteries) by slowing the development of plaque and blood clots, which can clog arteries.
People with diabetes often have high triglyceride and low HDL levels. Fsh oil can help lower triglycerides and apoproteins (markers of diabetes), and raise HDL, so eating foods or taking fish oil supplements may help people with diabetes. Another type of omega-3 fatty acid, ALA (from flaxseed, for example) may not have the same benefit as fish oil. Some people with diabetes can’ t efficiently convert LNA to a form of omega-3 that the body can use. Also, some people with type 2 diabetes may have slight increases in fasting blood sugar when taking fish oil, so talk to your doctor to see if fish oil is right for you.
Most clinical studies examining omega-3 fatty acid supplements for arthritis have focused on rheumatoid arthritis (RA), an autoimmune disease that causes inflammation in the joints. A number of small studies have found that fish oil helps reduce symptoms of RA, including joint pain and morning stiffness. One study suggests that people with RA who take fish oil may be able to lower their dose of non-steroidal anti-inflammatory drugs (NSAIDs). However, unlike prescription s, fish oil does not appear to slow progression of RA, only to treat the symptoms. Joint damage still occurs.
Laboratory studies suggest that diets rich in omega-3 (and low in the inflammatory omega-6 f) may help people with osteoarthritis, although more study is needed. New Zealand green lipped mussel (Perna canaliculus), another potential source of fish oil, has been reported to reduce joint stiffness and pain, increase grip strength, and improve walking pace in a small group of people with osteoarthritis. For some people, symptoms got worse before they improved.
An analysis of 17 randomized, controlled clinical trials looked at the pain relieving effects of omega-3 fatty acid supplements in people with RA or joint pain caused by inflammatory bowel disease (IBS) and painful menstruation (dysmenorrhea). The results suggest that omega fats along with conventional therapies such as NSAIDs, may help relieve joint pain associated with these conditions.
Systemic lupus erythematosus (SLE)
Several small studies suggest that EPA and fish oil may help reduce symptoms of lupus, an autoimmune condition characterized by fatigue and joint pain. However, two small studies found fish oil had no effect on lupus nephritis (kidney disease caused by lupus, a frequent complication of the disease).
Some studies suggest that omega fish oil may help increase levels of calcium in the body and improve bone strength, although not all results were positive. Some studies also suggest that people who don’ t get enough of some essential fatty acids (particularly EPA and gamma-linolenic acid [GLA], an omega-6 fatty acid) are more likely to have bone loss than those with normal levels of these fats. In a study of women over 65 with osteoporosis, those who took EPA and GLA supplements had less bone loss over 3 years than those who took placebo. Many of these women also experienced an increase in bone density.
Studies have found mixed results as to whether taking omega-3 fatty acids can help depression symptoms. Several studies have found that people who took omega-3 fatty acids in addition to prescription antidepressants had a greater improvement in symptoms than those who took antidepressants alone. However, other studies have found no benefit.
Studies are also mixed on whether omega-3 fatty acids alone have any effect on depression. Depression is a serious illness and you should not try to treat it on your own. See a doctor for help.
In a clinical study of 30 people with bipolar disorder, those who took fish oil in addition to standard prescription treatments for bipolar disorder for 4 months experienced fewer mood swings and relapse than those who received placebo. But another 4-month long clinical study treating people with bipolar depression and rapid cycling bipolar disorder did not find that EPA helped reduce symptoms.
Preliminary clinical evidence suggests that people with schizophrenia may have an improvement in symptoms when given omega-3 fatty acids. However, a recent well-designed study concluded that EPA supplements are no better than placebo in improving symptoms of this condition.
Attention deficit/hyperactivity disorder (ADHD)
Children with attention deficit/hyperactivity disorder (ADHD) may have low levels of certain essential fatty acids (including EPA and DHA). In a clinical study of nearly 100 boys, those with lower levels of omega-3 fatty acids had more learning and behavioral problems (such as temper tantrums and sleep disturbances) than boys with normal omega-3 fatty acid levels.
However, studies examining whether omega-3 fatty acids help improve symptoms of ADHD have found mixed results. A few studies have found that omega-3 fatty acids helped improve behavioral symptoms, but most were not well designed. One study that looked at DHA in addition to stimulant therapy (standard therapy for ADHD) found no effect. More research is needed, but eating foods that are high in omega-3 fatty acids is a reasonable approach for someone with ADHD.
In one clinical study, 13 people with sun sensitivity known as photo dermatitis showed less sensitivity to UV rays after taking fish oil supplements. However, topical sunscreens are much better at protecting the skin from damaging effects of the sun than omega-3 fatty acids. In another study of 40 people with psoriasis, those who took EPA with their prescription s did better than those treated with the s alone. However, a larger study of people with psoriasis found no benefit from fish oil.
Inflammatory bowel disease (IBD)
Results are mixed as to whether omega-3 fatty acids can help reduce symptoms of Crohn’ s disease and ulcerative colitis, the two types of IBD. Some studies suggest that omega-3 fatty acids may help when added to , such as sulfasalazine (a standard for IBD). Others find no effect. More studies are needed. Fish oil supplements can cause side effects that are similar to symptoms of IBD (such as flatulence, belching, bloating, and diarrhea).
Studies examining omega-3 fatty acids for asthma are mixed. In one small, well-designed clinical study of 29 children with asthma, those who took fish oil supplements rich in EPA and DHA for 10 months reduced their symptoms compared to children who took placebo. However, most studies have shown no effect.
A questionnaire given to more than 3,000 people over the age of 49 found that those who ate more fish were less likely to have macular degeneration (a serious age-related eye condition that can progress to blindness) than those who ate less fish. Similarly, a clinical study comparing 350 people with macular degeneration to 500 without the eye disease found that those with a healthy dietary balance of omega-3 and omega-6 fatty acids and more fish in their diets were less likely to have macular degeneration.
In one study of 42 women, they had less menstrual pain when they took fish oil supplements than when they took placebo.
Eating foods rich in omega-3 fatty acids seems to reduce the risk of colorectal cancer. For example, Eskimos, who tend to have a high-fat diet but eat significant amounts of fish rich in omega-3 fatty acids, have a low rate of colorectal cancer. Animal studies and laboratory studies have found that omega-3 fatty acids prevent worsening of colon cancer. Preliminary studies suggest that taking fish oil daily may help slow the progression of colon cancer in people with early stages of the disease. If you have colorectal cancer, ask your doctor before taking any supplements.
Although not all experts agree, women who eat foods rich in omega-3 fatty acids over many years may be less likely to develop breast cancer. More research is needed to understand the effect that omega-3 fatty acids may have on the prevention of breast cancer.
Population based studies of groups of men suggest that a low-fat diet including omega-3 fatty acids from fish or fish oil help prevent the development of prostate cancer.
Fish, plant, and nut oils are the primary dietary source of omega-3 fatty acids. Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are found in cold-water fish such as salmon, mackerel, halibut, sardines, tuna, and herring. ALA is found in flaxseeds, flaxseed oil, canola (rapeseed) oil, soybeans, soybean oil, pumpkin seeds, pumpkin seed oil, purslane, perilla seed oil, walnuts, and walnut oil. Other sources of omega-3 fatty acids include sea life such as krill and algae.
Both EPA and DHA can be taken in the form of fish oil capsules. Flaxseed, flaxseed oil, fish and krill oils should be kept refrigerated. Whole flaxseeds must be ground within 24 hours of use, so the ingredients stay active. Flaxseeds are also available in ground form in a special mylar package so that the components in the flaxseeds stay active.
Be sure to buy omega-3 fatty acid supplements made by established companies who certify that their products are free of heavy metals such as mercury, lead, and cadmium.
How to Take It:
Dosing for fish oil supplements should be based on the amount of EPA and DHA, not on the total amount of fish oil. Supplements vary in the amounts and ratios of EPA and DHA. A common amount of omega-3 fatty acids in fish oil capsules is 0.18 grams (180 mg) of EPA and 0.12 grams (120 mg) of DHA. Five grams of fish oil contains approximately 0.17 – 0.56 grams (170 -560 mg) of EPA and 0.072 – 0.31 grams (72 – 310 mg) of DHA. Different types of fish contain variable amounts of omega-3 fatty acids, and different types of nuts or oil contain variable amounts of LNA. Fish oils contain approximately 9 calories per gram of oil.
Children (18 years and younger)
There is no established dose for children. Omega-3 fatty acids are used in some infant formulas. Fish oil capsules should not be used in children except under the direction of a health care provider. Children should avoid eating fish that may be high in mercury, such as shark, swordfish, king mackerel, and tilefish. (See Precautions section.)
Do not take more than 3 grams daily of omega-3 from capsules without the supervision of a health care provider, due to an increased risk of bleeding.
- For healthy adults with no history of heart disease: The American Heart Association recommends eating fish at least 2 times per week.
- For adults with coronary heart disease: The American Heart Association recommends an omega-3 fatty acid supplement (as fish oils), 1 gram daily of EPA and DHA. It may take 2 – 3 weeks for benefits of fish oil supplements to be seen.
- For adults with high cholesterol levels: The American Heart Association recommends an omega-3 fatty acid supplement (as fish oils), 2 – 4 grams daily of EPA and DHA. It may take 2 – 3 weeks for benefits of fish oil supplements to be seen.
