These fatty acids are essential for human health, playing crucial roles in various physiological functions. They contribute to heart health by reducing triglyceride levels, lowering blood pressure, and decreasing the risk of arrhythmias. In the realm of brain health, omega - 3s support cognitive development in children and may help prevent cognitive decline in the elderly.
