Omega-3 fish oil is an oil extracted from the tissues of fatty fish; its key active ingredients are two long-chain Omega-3 polyunsaturated fatty acids—eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). The human body cannot synthesize these essential fatty acids on its own and must obtain them through diet or supplements.

Significantly lowers triglycerides: This is currently the most well-established and evidence-backed benefit of fish oil. High-purity Omega-3 fatty acids effectively reduce hepatic triglyceride synthesis. A daily intake of 1–2 grams of EPA and DHA can lower triglyceride levels by 15%–20%.
Anti-inflammatory effects: Omega-3 fatty acids possess anti-inflammatory properties.
Modestly lowers blood pressure: Taking fish oil supplements can lead to a mild to moderate reduction in blood pressure.
Supports brain and eye health: DHA is a key structural component of the brain and retina, playing a crucial role in maintaining cognitive function and visual health.
