Omega-3 fatty acids are substances that are often given to people who are concerned about their risk for heart disease. These fats can be found in flaxseed oil and fatty fish, such as sardines, mackerel, herring and lake trout. Your doctor may also prescribe supplements with omega-3 fatty acids, including the medication Lovaza.
Omega-3 Fatty Acids
Omega-3 fatty acids are a type of polyunsaturated fat. These fats play an important role in regulating your brain function, and they are also needed for proper growth and development, reports the University of Maryland Medical Center. Your body lacks the enzymes necessary to make these fats, which is why they are called essential fatty acids. All omega-3 fatty acids must come from food or supplements. In addition to their role in growth and development, omega-3s can also improve your cardiovascular health.
Omega-3 Fatty Acids and Heart Disease
Omega-3 supplements can be prescribed for lowering your risk of heart disease and stroke. Omega-3s can help lower your blood pressure, which reduces the strain on your heart and can decrease your risk of developing atherosclerosis. Omega-3 fatty acids can also help lower your triglycerides and increase your levels of HDL, or "good," cholesterol; both of these effects can help prevent atherosclerosis. And omega-3s make it harder for platelets to stick together, MayoClinic.com reports, which can prevent blood clots that can lead to heart attack or stroke.
Lovaza and Other Forms
Lovaza is the only prescription omega-3 fatty acid supplement that has been approved by the Food and Drug Administration. Over-the-counter products containing omega-3 fatty acids can also be purchased. Drugs.com recommends that you follow the directions listed on the package or on your prescription when you take these supplements to ensure that you are getting the right dosage. Lovaza is usually prescribed along with lifestyle changes, including weight control, exercise and dietary modifications.
Risks
Omega-3 fatty acids are safe for most people to take, although some supplements, including fish oil, can leave behind a fishy aftertaste. You should talk to your doctor before taking supplements with these beneficial fats if you have diabetes, thyroid problems, liver disease or a disorder of the pancreas, Drugs.com reports. Because omega-3 fatty acids help prevent blood clots, you should not consume them if you are taking warfarin or other blood-thinning medication.
