Why People Use
What Are EPA & DHA?
EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) are the two longchain omega3 fatty acids that give fish oil its reputation. EPA is known for calming inflammation, while DHA is a major building block of brain and eye cells. According to , our bodies cant make enough of these on their own, so we rely on foods or supplements to fill the gap.

Risks & SideEffects
Common Complaints
Most people feel fine, but a few note a fishy aftertaste, mild nausea, or loose stools. These are usually solved by taking the capsule with a big meal or switching to an entericcoated version.
When To Hit Pause
If youre on blood thinners, pregnant, or nursing, doublecheck with your doctor before loading up on omega3s. Very high doses (above 5g/day) can lengthen bleeding time, which is why doctors often set a ceiling for patients with clotting disorders.
Minimising The Upset
- Start with 500mg EPA/DHA and ramp up slowly.
- Choose redistilled or molecularly filtered products they strip out mercury and PCBs.
- Take capsules with food that contains some fat; it boosts absorption.
Choosing The Best
Purity & Source
The gold standard for purity is thirdparty certification (IFOS, USP, or NSF). Products that list wildcaught Alaskan pollock, processed within hours tend to have the lowest contaminant load.
EPA/DHA Ratio You Need
For cholesterollowering, aim for at least 1g EPA + DHA per serving, preferably 23g split across the day. Women often benefit from a slightly higher DHAtoEPA ratio (2:1) to support hormonal balance and skin health.
Form Factor
Softgels are convenient, liquids work if you have trouble swallowing, and algaederived capsules give vegans the same DHA boost without fish odor.
