Some interesting information has been released recently regarding the use of pure fish oil for maintaining good health. Many studies have been done with encouraging results in reference to the essential fatty acids DHA and EPA present in the oils of cold-water fatty fish, and the effect these nutrients have on dementia. DHA is a vital component in the operation of brain cell membranes, which are crucial for brain signal transmission. Brain function is hindered when adequate amounts of this omega-3 essential fatty acid are lacking. Several studies have come to the same conclusion that Alzheimer’s disease and similar brain maladies may be more common in patients who are deficient in DHA.

In 2006 researchers at Tufts University studied just over 850 men and women to see if pure fish oil for dementia could be successful. Their results showed that people who have higher blood levels of DHA cut their dementia risk by almost half (forty seven per cent) compared to those with the lowest levels. In this particular study, eating cold-water fatty fish like salmon, mackerel, and sardines three times a week led to the most elevated DHA levels. That same year a Swedish study discovered that consumingpure fish oil dietary supplements could reduce the rate of mental decline in patients with mild Alzheimer’s disease. Positive results were found in both groups, whether consuming actual seafood or by taking pure fish oil in capsule form.

The essential fatty acid EPA is a major factor in maintaining good heart health. Dariush Mosaffarian, MD, of the Harvard School of Public Health stated that even by eating a limited amount of seafood, you could extensively reduce your danger of cardiac arrest. He goes on to share the following research conclusions. Outcomes from thirty large studies conducted worldwide revealed that individuals who eat as little as two servings of fish weekly reduce the threat of a fatal heart attack by about thirty six per cent.


The American Heart Association (AHA) states that their research has demonstrated that omega-3 fatty acids found in fish oil decrease danger of arrhythmia, lower triglyceride levels, and reduce blood pressure slightly. The AHA advises patients with coronary heart disease to take about one gram of EPA plus DHA per day either from fatty fish or in a dietary supplement. People who are in need of decreasing their triglyceride levels should take 2 to 4 grams of EPA plus DHA capsules daily. They recommend consulting with a physician in these areas first to decide upon proper dosage according to each individual’s particular medical situation.

You may be wondering if you can even eat the amount of fish it takes to see healthful results. If you are concerned about the possibility of mercury contamination in the fish you may eat, you are not alone. Large doses of this element have been proven to cause brain damage in children. In fact the FDA and the Environmental Protection Agency put out a combined statement in 2004 advocating that women of childbearing age and small children ingest no more that twelve ounces of fish weekly. They go on to advise that this group of people completely avoid consuming king mackerel, swordfish, tilefish and shark, because of their high mercury content.

Pure fish oil dietary supplements are an effectual way to get the vital omega-3 essential fatty acids that you would typically get from eating fish. Be very cautious in choosing a specific supplement. Look closely to be sure you are getting a capsule that has DHA and EPA in it as these are so critical to heart and brain health as mentioned above. Another important factor to look for is if that product has been molecularly distilled to guarantee youpure fish oil free from all contaminants.
