Fish Oil
Snapshot
Fish oil is a rich source of longβchain omegaβ3 fatty acidsβEPA and DHAβthat support cardiovascular health, cognitive function, joint comfort, and antiβinflammatory balance.

What is Fish Oil?
Fish oil is extracted from the tissues of oily fish such as salmon, mackerel, sardines, and anchovies. It provides concentrated levels of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), essential fatty acids that the body cannot efficiently produce on its own.
Where It Comes From
Highβpurity fish oil supplements are made from coldβwater, fatty fish harvested sustainably. The oil is extracted, purified to remove contaminants (like mercury and PCBs), and often molecularly distilled to concentrate EPA and DHA.
Key Nutrients & Compounds
Fish oil supplies EPA and DHA in triglyceride or ethyl ester forms. It also contains minor amounts of other omegaβ3s (DPA) and lipidβsoluble vitamins A and D, depending on processing and oil source.
Health Benefits
EPA and DHA in fish oil promote heart health by lowering triglycerides, reducing blood pressure, and improving endothelial function. They support brain health, memory, and mood regulation, and alleviate joint stiffness through antiβinflammatory pathways. Fish oil also benefits eye health and may reduce risk of ageβrelated macular degeneration.
Recommended Dosage
General health recommendations are 250β500β―mg combined EPAβ―+β―DHA daily. Higher therapeutic dosesβ1,000β4,000β―mg per dayβare used for triglyceride management or inflammatory conditions under medical guidance.
How to Use It
Fish oil is available in softgels, liquids, and emulsions. Take with meals containing fat to enhance absorption. Entericβcoated capsules can reduce fishy aftertaste and reflux.
Who Should Use It?
Ideal for individuals with cardiovascular risk factors, cognitive concerns, joint discomfort, or low fish intake. Also beneficial during pregnancy and lactation for fetal neurodevelopment.
Possible Interactions or Cautions
High doses can increase bleeding risk, especially with anticoagulants. Some may experience gastrointestinal upset or fishy burps. Choose thirdβparty tested products to ensure purity and potency.
Final Thoughts
Fish oil remains a cornerstone supplement for comprehensive omegaβ3 support. Its benefits span heart, brain, joint, and eye health, making it a foundational component of balanced supplementation.
