Health benefits of omega-3 fatty acids

Omega-3 fatty acids, particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), offer several health benefits, especially for cardiovascular and neurological health.

Omega-3 fatty acids have been shown to reduce the risk of cardiovascular disease (CVD), including coronary heart disease and heart attack.

Cardiovascular benefits : Omega-3 fatty acids have been shown to reduce the risk of cardiovascular disease (CVD), including coronary artery disease and heart attack. They achieve this by modulating risk factors such as blood lipids, blood pressure, heart rate, platelet aggregation, endothelial function, and inflammation. The American Heart Association recommends omega-3 fatty acids for patients with hypertriglyceridemia to lower triglyceride levels and reduce the risk of atherosclerotic cardiovascular disease. [1-5]

Neurological Benefits : Omega-3 fatty acids are essential for brain development and function. They play a role in maintaining the structural and functional integrity of the nervous system, regulating cognitive abilities, and supporting brain development. They have therapeutic value in the treatment of depression, neuropsychiatric disorders, and neurodegenerative diseases. [6]

Anti-inflammatory and antioxidant effects : Omega-3 fatty acids help regulate inflammatory processes and oxidative stress, which is important in the prevention and treatment of chronic diseases characterized by increased inflammatory responses, such as cardiovascular diseases.

Dosage : While dosage may vary, the American Heart Association recommends that people with established coronary artery disease consume approximately 2-3 grams of EPA and DHA daily. For people with hypertriglyceridemia, 2-4 grams of EPA and DHA daily in capsule form is recommended under medical supervision.

In summary, omega-3 fatty acids offer significant benefits for cardiovascular and neurological health, primarily through their anti-inflammatory, lipid-lowering, and neuroprotective effects.

Omega-3 fatty acids & inflammation

Omega-6 fatty acid - Omega-3 fatty acid & **inflammation**

Omega-3 fatty acids play a role. One of the primary mechanisms involves the modulation of prostaglandins and leukotrienes derived from arachidonic acid, a pro-inflammatory omega-6 fatty acid. Omega-3 fatty acids compete with arachidonic acid for the same enzymes, resulting in the production of less pro-inflammatory omega-6 fatty acids .

In addition, omega-3 fatty acids are precursors of specific pro-resolving mediators (SPMs) such as resolvins, protectins, and maresins. These SPMs actively promote the resolution of inflammation by reducing the production of pro-inflammatory cytokines and improving the clearance of inflammatory cells and debris.

Clinical studies have shown that omega-3 supplementation can reduce inflammatory markers. For example, EPA supplementation has been shown to reduce vascular inflammatory markers such as VCAM1 and CCL2, which are crucial for the pathogenesis of:

In overweight pregnant women, omega-3 supplementation reduced inflammatory markers such as CRP, IL-6, IL-8 and TNF-α in both adipose tissue and

Furthermore, omega-3 fatty acids have been found to modulate macrophage polarization and promote a shift towards the anti-inflammatory M2 phenotype, which is important in chronic inflammatory diseases such as liver
