When buying omega-3 we often see the words “EPA” and “DHA” on the label · Both are omega-3s, but they do different jobs · Knowing the difference helps you choose to match your goal, whether that is caring for your heart, your brain or inflammation · This article sums it up simply so you know how to choose
inflammation/heart
brain/eyes
usually contain both
The long-chain omega-3s the body uses well come in two main forms: EPA (Eicosapentaenoic acid) and DHA (Docosahexaenoic acid) · Both are found in large amounts in fish oil and algae · Although both are omega-3s, their roles in the body are not quite the same
1 What EPA does
- Inflammation — EPA is a precursor of substances that help regulate inflammation in the body
- Heart and blood-vessel health — Most research on triglycerides/the heart focuses on EPA
- Mood — Some studies are interested in the role of EPA in mental well-being
2 What DHA does
- Brain and nervous system — DHA is a major structural component of the brain
- Eyes — It is a component of the light-sensing layer of the eye (the retina)
- Development — Important for brain development in the unborn baby and in childhood
3 How to choose an omega-3 that matches your goal
| Goal | Focus on |
|---|---|
| Heart/triglyceride care | A high proportion of EPA |
| Brain/memory/eyes | Enough DHA |
| Overall care | Both EPA and DHA |
What you should look at is the actual EPA/DHA content per capsule (not just “fish oil 1000 mg”), purity and heavy-metal control
💡 Did you know? BLB P is a formula of9 cold-pressed oils with CoQ10 that provides a variety of good fatty acids for holistic care of the heart, blood vessels and the body’s balance · Thai FDA 26-1-10867-5-0050 · Halal · A dietary supplement, not a medicine; it has no effect in treating heart or blood-vessel disease
4 The honest picture
EPA and DHA are not rivals but one team, each good at a different job · For most people, getting both in suitable proportions is the balanced choice · And don’t forget that meals with fish are a good natural source of omega-3
