Choosing Fish Oil Supplements

Choosing the right fish oil supplement may not always be easy. One of the things to consider is that one should know about what makes such supplements valuable to health, which is its omega 3 fatty acid content. There are various sources of such essential fatty acids. It can be easy to question if there is indeed a difference between getting this nutrient from different sources.

Three Types Of Omega 3 Fatty Acids
One of the things that people should know is that there are three known types of omega 3 fatty acids, the essential nutrient found in fish oil supplements. The three types of omega 3 fatty acids include EPA, DHA and ALA. ALA, or alpha-linolenic acid is a short chain omega 3 fatty acid that is usually found in plant sources such as flax seed, walnuts, canola and soybean oil. DHA or docosahexaenoic acid and EHA or eicosapentaenoic acid are considered as long chain omega 3 fatty acids. The latter two are those found in fish oil supplements.

The difference between short chain omega 3 fatty acids such as ALA and long chain omega 3 fatty acids has to do with how the body processes them. In order for the body to make use of such essential fatty acids, it has first to convert the short chain types into its long chain form. This does not usually happen readily. That is why fish oil supplements are considered more effective in providing the omega 3 fatty acids that it needs because it is already the long chain form which does not require any more conversion before the body can use them.

Effectiveness
One of the other things to consider when choosing between fish oil supplements and ones that are sourced from plants deals with their effectiveness and benefits. Experts believe that the long chain omega 3 fatty acids being sourced from fish oils prove to be more effective in terms of health benefits. These essential fatty acids have already been known to offer some benefit in preventing heart disease. With the short chain fatty acid ALA however, experts are not too sure if ever it does provide the same benefit because it may still require additional conversion before it can be used by the body.

Fish Oil Source
Now that one already knows the difference between omega 3 fatty acids sourced from fish as well as those from plants, it seems that fish oil seem to have the upper hand. But this time there are some other things to consider. In order to get the type of fish oil supplements that offer the best source of long chain omega 3 fatty acids, people should know where they are being sourced from.

One important thing for consumers to look at when buying fish oil supplements is the label. It should contain information of where the fish oil used in the supplement is being sourced from. Because there can be more than just one fish species to source out such supplements, it is important to clearly know what types of fishes these may be.

Certain labels may contain information of the fish oil being sourced from salmon, tuna or anchovies. This might be considered safe. But if labels on the said supplements only tell of fish oil or marine lipids, this should ring some warning bells. It may be possible that fish oils in such supplements may not be too sure where the source may come from, which might also cast some doubt on the purity of the fish oil being used

How Fish Oil Can Benefit Your Health

Fish oils are extracted fats from fish, a concentrated solution of omega-3 EFAs. It is the best source of omega-3 EFAs. You could add more omega-3 EFAs to your diet in the form of alpha-linolenic acid (ALA). The richest plant sources of ALA are the leaves and seeds of the perilla plants common in North America, Japan, Korea, China and Vietnam.

Green plants and algae also contain ALA as well as linseed oil. However, fats or oil from fish is considered the most important dietary source of omega-3 EFAs because it has concentrated amounts of the ALA derivatives EPA and DHA. These two nutrients are found almost exclusively in seafood.

Eating fish on a regular basis has its own risk as you are can never be sure if the fish you are eating has no toxins on it such as mercury and PCBs. During the manufacture of fish oils, toxins are eliminated. The supplements are meticulously purified to remove heavy metals such as mercury, lead, PCBs and other toxins as well as to reduce the incidence of rancidity and improve the taste and quality of the fish oil.

These makes fish oils as safe and effective food supplement. A 1-gram fish oil capsule contains about 180 mg of EPA and 120 mg of DHA. An intake of three 1-gram capsules would provide 0.9 gram (900 mg) of EPA and DHA. This means it comply the daily dosage recommended by the American Heart Association. However, you should always bear in mind that fish oil supplements are basically dietary supplements, not drugs.

Studies shows that many people are getting too much of the wrong kinds of fats found in animals (saturated fats) and vegetables (polyunsaturated fats), and need the fish oil to balance the family of fat nutrients. Intake of the wrong kinds of fats should be lowered to total 20 to 30 percent of daily calorie serving while fats found in the oils of certain fish should be appreciably increased.

Fish oil prevents and/or alleviates heart disease, high blood pressure, arthritis and migraine, headaches, may be protective against cancer, immune deficiency diseases, kidney disease and others. Fish oils also have two special nutrients that protect the heart and arteries, reduce pain, inflammation and swelling, and protect cell membranes. Omega-3 EFAs found in oily fishes are believed to be essential for the healthy development of brain, retina, and nervous tissue among fetus and infant.

During pregnancy these fatty acids are transferred from the mother’s tissues to the fetus. However, the FDA has strict guidelines on eating fish during pregnancy because of the possibility of mercury or other toxic substances that may contain in fishes and the best solution is to take fish oil as food supplement

Over the past 30 years more than 7,000 scientific studies have provided evidence supporting the effectiveness of fish oil and omega-3 EFAs in the prevention and treatment of our most common diseases. Hundreds of clinical trials support the efficacy of fish oil’s omega-3 essential fatty acids in preventing, mitigating, and remedying an incredible range of health conditions. Some scientific and medical communities however are resisting to these facts and still support pharmacological treatment.

As a traditional dietary supplement that encourages good health, fish oil is a preventive medicine but as a natural alternative to NSAIDs or non-steroidal anti-inflammatory drugs and other pharmacological and medical treatments, it is complementary medicine.

With all the undergoing studies to prove its affectivity, fish oil is on the threshold of crossing over into traditional Western medicine.
