The Importance Of Selecting The Right Fish Oil Pills
By Ng Peng Hock
Despite the possible presence of contaminants in fish, benefits of eating fish cannot be denied as supported by numerous researches and studies. Fish contain omega-3 fatty acid that helps reduce the risk of heart disease.
One possible way to prevent one from taking contaminated fish is to consume carefully selected fish oil supplements. Techniques such as molecular distillation that employing pressure and temperature, can purify possible environmental pollutants contained in fish.
There are plenty of fish oil supplements available in the market. Their quality and potency, however, can differ widely. One should take note that diarrhea and other minor discomfort can often occur by taking supplements that turn rancid or that contain ingredients that are not adequately purified.
Another important issue if dosage. Fish oil can help the heart by thinning the blood. High levels of fish oil might increase the risk of bleeding, and may cause harm instead if combined with blood thinning medication. If one is on medication pertaining to cardiovascular treatment, he or she should seek advice from the doctor about the appropriate dosage before taking any fish oil supplement.
When choosing fish oil, it is also necessary to note their levels of fatty acids that offer the kind of healthy benefits required. For example, 1000 mg of fish oil with 180 mg of EPA (eicosapentaenoic acid) and 120 mg of DHA (docosahexaenoic acid) provide 300 mg (not 1000 mg) of omega-3 fats.
Besides omega-3, consumers should look at other ingredients such as vitamin A and D in cod liver oil and added vitamin E in fish oil, as these may not be good for everybody. Fish oil supplements may be beneficial only for those with high triglyceride levels in reducing the levels.
Triglycerides are the chemical form in which fat exists in the body. High levels increase risk of hypertension, diabetes, and heart disease. This is because a single fish oil capsule contains about 30 times the amount of omega-3 fatty acids as a single fish portion. On average, a 113.5 g serving of oily fish contains about 1.5g of omega-3 fatty acids.
Most regulators stipulate a level of purity but standards vary considerably. The European Union standards are among the strictest, being more cautious than those imposed by the FDA in United States. Environmental Defense, a United States non-profit organization, has conducted an international study of fish and fish oil supplements. The group helps consumers decide how to obtain adequate amounts of omega-3 fatty acids without contaminants. Three brands that are on the list of "Best Choice" supplements are Nordic Naturals, which is made in Norway, and Shaklee and Usana brands, which are made in the United States. These brands certify that their supplements are free from heavy metals, dioxins, and PCBs.
