Why Fish Oil Remains a Powerhouse for Heart Health and Beyond
Fish oil, often called omega-3, remains one of the most widely used dietary supplements worldwide. Derived from oily fish, it contains high levels of omega-3 polyunsaturated fatty acids (PUFAs), particularly EPA and DHA—nutrients linked to a range of health benefits, including heart health and health equity.
Scientific interest in fish oil grew in the 1970s after researchers uncovered its heart-protective properties. Since then, omega-3s have been studied for their ability to lower triglycerides, a type of fat in the blood that can increase heart disease risk. A 2023 study confirmed that consuming more than 2 grams daily of combined EPA and DHA is necessary to achieve meaningful reductions in triglyceride levels.
Our bodies cannot produce enough omega-3s on their own, so they must be obtained through diet or supplements. Beyond heart health, these fatty acids play a key role in maintaining cell function by keeping membranes fluid and flexible. They are also promoted for their potential to improve mood, with some research indicating they may ease symptoms of clinical depression when used alongside antidepressants.
Fish oil's mild anti-inflammatory effects have further broadened its appeal. For people with inflammatory arthritis, it has been shown to reduce joint tenderness and morning stiffness, offering some relief from chronic discomfort.
Fish oil continues to be a popular supplement due to its well-documented benefits for heart health and inflammation. While research supports its role in lowering triglycerides and aiding joint mobility, its effectiveness in other areas, such as mood regulation, remains under investigation. As with any supplement, individual results may vary depending on dosage and overall health.
