One can either eat fatty fish or ingest supplements of fish oil to obtain nutrients such as omega-3 fatty acids. Sea fish like mackerel,tuna, salmon, mullet, sturgeon, anchovy, bluefish, herring, sardines, menhaden and trout are sources of high dose fish oil and every 3.5 ounces of each of these fish offers 1 gram of omega-3 fatty acids.
Fish oil supplements address a range of health conditions including those related to the heart and blood system – high blood pressure, high triglyceride levels, risk of heart attacks and strokes. Fish is also considered to be ‘brain food’ as it has shown to benefit people with psychosis, depression, Alzheimer’s disease and attention deficit hyperactivity disorder.
High dose fish oil supplements are obtained from fish like herring, mackerel, halibut, tuna, cod liver, salmon, seal blubber and whale blubber. With negligible amounts of vitamin E, such supplements are prevented from spoilage. Along with fatty acids like eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), fish oil supplements can also contain other nutrients like iron and calcium.
Women often ingest fish oil to avoid painful periods, complications with pregnancy, breast pain and high blood pressure levels. Studies have also suggested that omega-3 fatty acids can bring relief to those who suffer from movements disorders, developmental coordination disorders, diabetes, asthma, obesity, dyslexia, osteoporosis, kidney problems, psoriasis and some forms of cancer.
However the preparation of fish determines the kind of health benefit you obtain. If fish is eaten baked or broiled, you will receive a lot more health benefits than if you were to consume it in fried form. Since many people cannot use their judgment to determine which fish is good for their health and which is not, they opt for high dose fish oil supplements instead.
Most benefits of fish oil stem from the presence of omega-3 fatty acids. Since the body does not produce any omega-3 fatty acids and it is not very practical to eat a lot of fish, supplements of fish oil have become very common among those who need to match the basic requirement.
Apart from health benefits, fish oil has also shown to improve skin and hair condition. A lot of people buy non-prescription supplements of fish oil as they are easily available over the counter at most nutrition stores and drug stores. However, high dose fish oil also has a few side effects and it may not be advisable that you buy a supplement for yourself without consulting a doctor.
