One of the most popular supplements for heart health is fish oil. Fish oil is a rich source of omega3 fatty acids which may be helpful in supporting the health of the heart and cardiovascular system. In fact, the evidence is clear enough that the FDA has endorsed the beneficial value of omega3 fatty acids. The agency says, supportive, but not conclusive, research shows that consumption of EPA and DHA omega3 fatty acids may reduce the risk of coronary heart disease. Omega3s may also help support the normal, healthy blood clotting process in the body, and normal, healthy levels of cholesterol and triglycerides. One of the fatty acids, DHA, is also important for the development and ongoing health of the central nervous system and brain function throughout life. Because fish oil is not part of a typical diet, a daily fish oil supplement may help provide the many health benefits of omega3 fatty acids.
