Introduction: Why Omega-3s Matter
Omega-3 fatty acids support brain function, heart health, reduce inflammation, and support overall cellular health. Most people don't get enough from diet alone. Quality supplementation is worth it.
EPA vs DHA: What's the Difference?
EPA (Eicosapentaenoic acid): Anti-inflammatory. Supports heart health and mood. 1,000-2,000mg daily is typical.
DHA (Docosahexaenoic acid): Brain and eye support. Supports cognitive function. 500-1,000mg daily is typical.
Both matter. Look for a product with at least 500mg EPA and 300mg DHA per serving.
Common Fish Oil Forms
Triglyceride Form
Best for: Natural absorption, cost-effectiveness
Natural form. Better absorption than ethyl esters. More expensive than some alternatives.
Ethyl Ester Form
Best for: Budget-conscious, shelf stability
Cheaper. Less natural form. Absorption is still decent. Standard in many supplements.
Phospholipid Form
Best for: Optimal absorption, premium quality
Most bioavailable. Naturally found in body. Premium pricing. Best absorption of all forms.

Best Time to Take Fish Oil
Take with largest meal of the day for better absorption. Consistent timing matters more than specific time of day. If you experience fishy aftertaste, freeze capsules before taking.
Fish Oil Side Effects
- Fishy aftertaste: Most common. Freeze capsules or take with food.
- Digestive upset: Take with meals. Usually resolves after a few days.
- Blood thinning: At very high doses. Rare at typical supplementation levels.
What the Science Shows
Research consistently supports omega-3 supplementation for:
- Cardiovascular health

- Anti-inflammatory effects
- Triglyceride reduction
Benefits typically appear after 4-12 weeks of consistent use.
