Studies have shown that Omega 3 fish oil benefits cardiac health including blood pressure, and a long list of other medical conditions. Fish oil contains Omega 3 fatty acids which include docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). Since the body does not produce Omega-3 fats on its own, Omega 3 fish oil supplements or food with Omega 3′s should be taken daily to ensure a healthy diet.
Foods with Omega-3 fatty acids include fish such as salmon, mackerel and tuna. It can also be found in some plant and nut oils. Since most people do not get enough fish oil in their daily diet, fish oil supplements may be recommended. The American Heart Association recommends a fish oil dosage of at least 500 mg daily for healthy people or up to three grams for those with heart related conditions. Additional fish oil supplements should only be consumed under the supervision of a doctor.
Omega 3 fish oil supplements can be purchased over-the-counter from pharmacies, grocery stores, vitamin shops and online for between ten and forty dollars depending on the contents and brand. The more expensive fish oil supplements normally list the DHA and EPA contents which might be higher and less concentrated than those that are less expensive. They are available in chewable, liquid or pill form.
Omega 3 fish oil side effects include fishy taste, upset stomach and heartburn. When taken in doses larger than three grams per day, possible life-threatening side effects can occur which include lowered immune system response and stroke. People with shellfish allergies should discuss the risks with their doctor before consuming fish oil supplements.
