What Is Omega-3? What Do EPA and DHA Mean?

Why is omega-3 discussed as an essential fat?

Humans cannot synthesise ALA and must obtain it from foods.

EPA/DHA production from ALA is limited.

Direct dietary or supplemental intake therefore receives separate attention.

What is EPA?

EPA is a marine long-chain omega-3.

It contributes to lipid mediator synthesis and is often studied cardiovascularly.

Many trials assess EPA or EPA+DHA in high-risk patients.[1]

They explain its importance and separate investigation across doses/formulations.

What is DHA?

DHA is structurally important in nervous and retinal tissue.

It is often studied for cognition, vision and neurodevelopment.

Child/adolescent doses and outcomes are highly heterogeneous.[2]

Are fish oil and omega-3 the same?

They are related but distinct. Fish oil is a raw material that may contain:

• EPA,
• DHA,
• other fatty acids

For example, a capsule containing 1000 mg fish oil describes total raw material; omega-3 is listed separately.

This is discussed in detail in a separate article.

Why are EPA, DHA and form studied together?

They contribute to membranes and physiology. Research considers amount, duration and form together.

Per-serving fish oil, total omega-3, EPA and DHA are useful daily-support information. Vitallin Omega-3 provides 680 mg total omega-3, 360 mg EPA and 240 mg DHA in 1000 mg fish oil, in TG form.

What does triglyceride form mean?

Supplements can use different chemical forms.

Triglyceride form means fatty acids attached to a glycerol backbone, resembling natural oil structure.

It is a technical property assessed with EPA+DHA, quality and form information.

How should Vitallin Omega-3's label be read?

Per softgel:

• 1000 mg fish oil
• 680 mg total omega-3
• 360 mg EPA
• 240 mg DHA
• 1.80 mg α-TE vitamin E

are present.

The product is provided in triglyceride form.

Key arithmetic:

1000 mg = fish oil

680 mg = total omega-3

These describe different label information.

What does science tell us?

1. Omega-3 includes different fatty acids, including EPA and DHA.
2. EPA and DHA have different roles.
3. Fish oil and total omega-3 give separate information.
4. Clinical outcomes depend on dose and population.
5. Research doses and populations determine interpretation context.
6. Assess labels by reading EPA/DHA separately.
