Fish oil is loaded with omega-3 essential fatty acids. These fatty acids decrease your risk of heart disease and stroke, reduce cholesterol levels and slightly lower blood pressure, according to Medline Plus. A variety of other health ailments may be treated by taking fish oil supplements including osteoporosis, ADHD and depression. Adding fish to your diet or taking a fish oil supplement are ways to increase your fish oil intake. When taking any supplement, always consult with your medical professional to avoid negative side effects from occurring.
Healthy Adults
Healthy adults with no history of coronary heart disease should add two servings of fatty fish to their diet a week, suggests the American Heart Association. One serving of fish equals 3.5 oz. It is important to prepare the fish in a healthy way, by baking or grilling the fish instead of pan-frying. Season the fish with herbs, spices and lemon juice instead of salt for a low-sodium alternative. Choose fatty fish, which are higher in omega-3 fatty acids. These fish include herring, mackerel and tuna. Avoid fish with high levels of mercury, such as tilefish, golden snapper and swordfish.
Coronary Artery Disease and Cholesterol
If you suffer from coronary artery disease, the American Heart Association suggests consuming 1 g of fish oil supplements daily. Patients attempting to decrease triglyceride and cholesterol levels are advised to take between 2 and 4 g of fish oil supplements. Supplements generally come in capsule form but are also available in a liquids version. If you are taking over 3 g of fish oil daily, it is highly advised to do so only under the direct care of a physician. High doses of fish oil may lead to internal bleeding, decreased immune function and high levels of "bad cholesterol," or LDL. Don't forget to exercise regularly and eat a heart-healthy diet when fighting heart disease.
Risks
Though fish oil is generally considered safe, some people should avoid fish oil supplements. If you suffer from severe irregular heart rhythms or angina, fish oil supplements may increase symptoms and lead to a possible heart attack. Fish oil supplements are also contraindicated if you have a defibrillator implanted, according to Medline Plus. Regular exercise and following a low-fat, low-sodium diet are suggested. Talk to your medical doctor for alternatives to taking fish oil supplements.
Side Effects
Less severe side effects include increased bleeding, such as nosebleeds and skin bruising. Seek medical attention if you are bruising on a regular basis and the bruises become painful. Fish oil supplements commonly give a person fishy breath or increased belches, even in small doses. Freeze the capsules to create a time-release formula. Experiment with different brands of fish oil to see which one affects your body the least, suggests MayoClinic.com.
