Fish oil supplements contain high amounts of omega-3 fatty acids. Fish oil contains docosahexaenoic acid and eicosapentaenoic acid. Consuming DHA and EPA reduces cholesterol levels, decreases heart irregularities and slightly lowers blood pressure --- all complications of heart disease. MedlinePlus states fish oil may possibly be effective for treating attention deficit disorder, rheumatoid arthritis, stroke and osteoporosis. The body does not create omega-3 fatty acids; dietary intake is the only source.
Dose
According to MedlinePlus, fish oil supplements are most likely safe for most American adults including pregnant or breastfeeding women when taken in doses of 3 milligrams or less daily. Still, some conditions may require more or less than the recommended amount; however, do not take more than 3 mg unless approved by a medical professional. There has not been an established recommended dosage for children. Some infant formula contains omega-3 fatty acids. MayoClinic.com states children should not take fish oil supplements unless directed by a medical doctor.
Side Effects
Taking fish oil comes with side effects. Common side effects of the supplement are burping and fishy breath. Socially embarrassing, the side effects may be avoided by freezing the fish oil capsules. The supplement may also increase the occurrence of nosebleeds. Nausea and loose bowel movements can also occur. MedlinePlus recommends eating food when taking fish oil supplements.
High Dosages
Taking more than 3 mg of fish oil may increase your risk of internal bleeding and decrease blood-clotting time. If you are taking medications known as anticoagulant and antiplatelets, use caution. These medications may include aspirin, clopidogrel, enoxaparin and heparin. Consult your medical professional about the appropriate dose of fish oil for your health condition. High doses may cause internal bleeding, leading to hemorrhagic stroke.
Alternative Methods
If swallowing a large capsule is difficult, consider increasing your fish consumption. The American Heart Association recommends eating fish twice a week. Each serving of fish is about 3 oz. Bake or grill the fish instead of pan-frying to decrease the amount of fat per serving. The American Heart Association suggests eating fatty fish such as salmon, flounder and pollock. Each fish contains different amounts of omega-3 fatty acids. Salmon contains between 1.1 to 1.9 g, flounder contains 0.48 g and pollock contains 0.45 g per 3-oz. serving.
