Omega-3 supplements play a vital role in heart health by contributing to lower levels of triglycerides and reducing inflammation. These essential fatty acids, found in fish oil, can help improve blood vessel function and lower blood pressure, which are crucial in preventing heart disease. Omega-3s also support healthy cholesterol levels, potentially reducing the risk of atherosclerosis. Regular intake of these supplements can lead to improved heart rhythm and overall cardiovascular wellness, making them beneficial for those at risk or aiming for better heart health.
