Omega-3 fish oil supplements are dietary supplements that provide omega-3 fatty acids, which are essential fats that the body cannot produce on its own. These supplements typically come in the form of soft gels, capsules, or liquid, and they are derived from fish oils, often from fatty fish such as salmon, mackerel, sardines, and anchovies.

Types of Omega-3 Fatty Acids

There are three primary types of omega-3 fatty acids:

1. Alpha-linolenic acid (ALA): Found in plant oils such as flaxseed, soybean, and canola oils.
2. Eicosapentaenoic acid (EPA): Found in marine oils.
3. Docosahexaenoic acid (DHA): Also found in marine oils.

Benefits of Omega-3 Fish Oil Supplements

1. Heart Health: Omega-3 fatty acids can help reduce the risk of heart disease by lowering triglycerides, reducing blood pressure, and preventing blood clots¹.
2. Brain Function: DHA is a major structural component of the brain and retina of the eye, and adequate levels are crucial for brain health².
3. Inflammation: Omega-3s have anti-inflammatory effects, which can help manage conditions such as arthritis³.
4. Mental Health: Some studies suggest that omega-3 supplements can help reduce symptoms of depression and anxiety⁴.
5. Pregnancy and Early Life: Omega-3 fatty acids are vital for brain development in infants, and pregnant women are often advised to ensure they get adequate amounts⁵.

Potential Side Effects

While generally considered safe, omega-3 fish oil supplements can have some side effects, especially at high doses:

• Fishy aftertaste
• Bad breath
• Heartburn, nausea
• Diarrhea
• Increased risk of bleeding

Considerations

• Purity: It's essential to choose high-quality supplements that have been tested for contaminants like heavy metals.
• Dosage: The typical dose ranges from 250–500 mg combined EPA and DHA per day, but higher doses may be recommended for specific health conditions.
