Understanding Fish Oil

Fish oil has a long history of being used as a nutritional supplement. It is generally derived from oil coming from the tissues of oily fish. There are many sources of fish that the world gets its fish oil supply from. But about 50 percent of all fish oil production in the world comes from farmed salmon.

Fish Oil Sources
Fish oil is primarily derived from farmed salmon. There are times when fish oil may also be sourced from other fatty fish notably mackerel, lake trout, flounder and tuna. But such types of fish are known to be predatory. And because of this, they run the risk of accumulating certain toxic substances such as mercury, dioxin and PCB’s. In order to avoid this and have fish oil sources known to be as clean as possible, farmed salmon are the best option.

Fish Oil Benefits
One of the things why fish oil has become quite a popular nutritional supplement around the world is because it is very rich in Omega -3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid. These compounds are said to help reduce the risk of coronary heart disease. There are also studies that say that these nutrients also have anti-cancer properties as well as may help in certain cases of depression.

Fish Oil Production
Production of fish oil is shared among a number of countries. But it has been seen that there was a substantial decrease in total fish oil supply, mainly because of declines suffered by a lot of the said countries. Countries such as Peru, Chile, Denmark, Iceland and Norway are known as the five major fish oil exporting nations.

Adverse Effects
Despite the various benefits that fish oil is said to offer as a supplement, medical experts still suggest caution in overusing it. There have been studies that indicate certain risks associated with fish oil. In some studies, there are suspected risks that researchers have found in the use of EPA and DHA fatty acids in fish oil.

Over usage of EPA and DHA, which is determined at more than three grams daily, are known to increase the risk of bleeding, especially in people who are also taking aspirin or warfarin. But further research may be needed to determine if EPA and DHA do offer such risks. Extreme dosage intake of fish oil is also associated with a higher risk of experiencing hemorrhagic stroke. In some individuals, fish oil intake may also affect LDL cholesterol levels.

Cardiac Risk
Because fish oil is still considered as fat, people with conditions arising from too much fat in their systems should also be cautious of taking fish oil as a supplement. Recent research seems to provide different results when it comes to how the fatty acids in fish oil affect people who may be suffering from heart disease or stroke.

In absence of definitive research, patients are being cautioned not to take fish oil without the recommendation from their doctor. People with certain heart problems or a history of heart disease should first talk with their doctors about the safety of taking fish oil supplements.

Surprising Benefits Of Using Fish Oil

The known benefits of fish oil are not just limited to the more common conditions. Of course, many people have already known how using fish oil may help improve skin health and reduce the risk of heart disease. But there are also surprising benefits that fish oil seem to offer to those who regularly consume them. Here are just some of them.

Depression And Anxiety
People may not be aware of it, but fish oil seems to help put people in a good mood. In fact, many studies have shown that fish oil may be beneficial in trying to help treat depression and anxiety in people. Thanks to the omega 3 fatty acids contained in fish oil, it seems a good means to relieve anxiety, depression, stress and sadness in people.

Fish oil seems to have good mood stabilizing properties that make them quite interesting as a treatment for depression and other related conditions. Evidence suggests that countries where oily fish such as salmon is regularly eaten also seem to have low incidence of depression. Similar studies involving prisoners have also shown that having them on a diet rich in omega 3 fatty acids resulted in a significant drop in homicide rates. Although more studies may be needed in order for such findings to be conclusive, it already shows some good evidences of the other surprising benefits of fish oil.

Cancer Fighter
It may seem quite surprising enough that fish oil may also benefit patients with certain forms of cancer. Preliminary studies have shown that fish oil may be useful in trying to delay the weight loss in people suffering from pancreatic cancer. Still further research may be needed to solidify this claim as well as how fish oil may affect certain types of cancers.

Type II Diabetes
Some studies also have shown positive findings on the effect of fish oil in Type II diabetes. Since people suffering from this form of diabetes are also prone to developing diseases such as coronary heart disease, atherosclerosis and stroke, medical experts believe that taking fish oil supplements may also help in trying to reduce such risks in diabetics. Some studies have already shown that fish oil may also be effective in lowering triglyceride levels in people with diabetes.

Pregnancy
Fish oil might also be able to help women bear healthier children. Taking fish oil supplements may help pregnant women ensure the healthy development of their child while still in the womb. The DHA found in fish oil is known to help babies undergo healthy eye and brain development. Pregnant women who are also taking fish oil supplements run fewer risks of having premature births, miscarriage or delivering babies with low birth weights. As an added benefit, pregnant women who regularly take fish oil supplements run lesser risks of getting into depression following the babys delivery.

Fertility
Fish oil supplements may also help in improving fertility. In a study done on male boars, those who were fed with a diet rich in fish oils were able to show better sperm quality. After ejaculation, the sperm from the boars fed with fish oil seem to resist the effects of lipid peroxidative attacks in the female boar genital tract, giving the sperm higher chances of conception.
