Fish oil is one of the most commonly consumed supplements among adults in the United States, according to a 2009 study by ConsumerLabs.com. The most common reason adults take fish oil is for heart-health benefits. Fish oil contains large amounts of omega-3 essential fatty acids. The body does not produce these acids. You must consume them through diet to receive their benefits and survive. The Cleveland Clinic reports the primary source of omega-3 fatty acids is fish, but some plants are also a rich source. Remember to consult with a health professional prior to taking fish oil supplements. Though most effects are positive, some negative side effects may occur.
Heart-Health Benefits
Fish oil reduces the amount of triglycerides circulating in your blood. Triglycerides are the form in which fat exists in food and in the body, describes the American Heart Association. Reducing your triglyceride levels may also reduce cholesterol levels and coronary artery disease. Additional heart-health benefits include lower risk of heart attack and stroke. Omega-3 fatty acids are natural blood thinners and do not allow blood platelets to clump together, reducing the risk of blood clots forming in the body. MedlinePlus reports fish oil is possibly effective for reducing blood pressure by widening blood vessels, and lowering blood pressure.
Rheumatoid Arthritis
Taking fish oil may reduce joint stiffness related to rheumatoid arthritis. The condition affects more women than men and primarily effects joints in the fingers and wrists, though it can affect any joint in the body, according to MedlinePlus. Taking a fish oil supplement may reduce the need for nonsteroidal anti-inflammatory medications such as naproxen. The supplement may also be taken with naproxen for additional benefits. However, fish oil only treats the symptoms of RA, unlike pain medications that may decrease progression, advises the University of Maryland Medical Center. Joint stiffness often occurs in the morning hours, so it is best to take the supplement at the beginning of the day.
Stroke
Fish oil supplements in low doses may reduce the risk of stroke. Taking a low dose of the supplement, about 1 g may be beneficial. Eating fish on a regular basis is also an option. MedlinePlus states consuming fish once or twice a week may reduce the risk of stroke by up to 27 percent. Choose fatty fish, which are higher in omega-3 fatty acids. These fish include herring, tuna, salmon and mackerel. One serving equals 3.5 oz. Grill or bake the fish instead of pan-frying to avoid consuming additional fat and grease. Season the fish with freshly squeezed lemon or herbs and spices instead of reaching for the saltshaker.
Warning
Though fish oil is generally safe for the adult population, some people should not take fish oil supplements. If you are taking anticoagulant or antiplatelet drugs, fish oil may cause increased bleeding. You may experience nosebleeds and bruise more easily. If you have a defibrillator installed, the fish oil may cause additional heart irregularities that can lead to a heart attack or even death. Always discuss the pros and cons of taking the supplement with your doctor.
