Omega-3 supplements are dietary supplements that contain the essential fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which are commonly found in fish oil. These fatty acids are known for their numerous health benefits, including reducing inflammation, improving heart health, supporting brain function, and potentially reducing the risk of chronic diseases such as heart disease, arthritis, and depression. Research on omega-3 supplements continues to explore their potential benefits and optimal dosage for various health conditions.
