EPA (Omega-3)

Eicosapentaenoic acid — DHA's partner in the marine omega-3 pair

All articles checked for accuracy against the GB NHC Register and all sources have citations with verified links to their relevant studies.

EPA is the other marine omega‑3 most supplements mention, but it rarely travels alone. It’s usually paired with DHA in fish and krill oils, and the law treats the pair — not EPA by itself — when it comes to authorised claims.

This article explains what EPA (eicosapentaenoic acid) is, where it comes from, how WellsparQ lists it on labels, and the precise regulatory position on authorised claims that involve EPA and DHA together. It focuses on clear facts and how to read product declarations against the required daily amounts.

Ingredient Snapshot

What it is

A long-chain marine omega‑3 fatty acid (eicosapentaenoic acid).

Where from

Mainly oily fish and krill; originally synthesised by microalgae.

Known for

Part of the EPA+DHA pair in marine oils and listed separately on supplement labels.

In WellsparQ

• Krill 500 Oil60 mg
• 3-6-9 Omega Oil60 mg

For reference

• "EPA and DHA contribute to the normal function of the heart."Beneficial effect obtained with 250 mg EPA + DHA per day ^²

EPA is the other half of the marine omega-3 story. Where DHA is the structural fatty acid built into brain and retina, EPA is more often studied for its role in the body's signalling and inflammatory pathways ^¹. The two almost always travel together in fish and krill oils, and they share the same important detail for a supplement label: the authorised European claims that involve EPA come with a specific daily amount attached. This page explains what EPA is and reads the label honestly against that threshold.

What EPA is

EPA — eicosapentaenoic acid — is a long-chain omega-3 polyunsaturated fatty acid (20 carbons, five double bonds). It sits one step "before" DHA in omega-3 metabolism, and the body can interconvert and elongate these fatty acids to a limited degree ^¹. EPA is a precursor to a family of locally acting signalling molecules (eicosanoids and specialised pro-resolving mediators) — which is the biology most of the research interest has centred on ^¹.

Like DHA, meaningful preformed EPA comes chiefly from oily fish and other marine sources, which ultimately derive it from microalgae ^¹. A modest amount can be made in the body from the plant omega-3 ALA, but that conversion is limited ^¹.

How WellsparQ declares it

Source: WellsparQ Supplements Database. Because the EPA here comes from krill and fish oil, these are animal-derived products — not suitable for vegans, and carrying the appropriate marine-allergen warnings ^¹.

The authorised claims — and the dose that governs them

EPA appears in EU/GB authorised health claims paired with DHA, not on its own for most functions ^²³:

(Separately, higher-intake claims exist for EPA+DHA and blood pressure and triglycerides, at defined larger doses ^²³.)

The honest reading for WellsparQ: Krill 500 Oil provides 100 mg EPA+DHA combined per capsule, below the 250 mg daily condition. Unless a serving is built to reach 250 mg combined per day, the heart claim cannot lawfully be used. So this page describes EPA's biology and the regulatory position, and stops there — it makes no benefit claim.

Why EPA and DHA are quoted separately

WellsparQ lists EPA and DHA as individual milligram figures rather than a single "omega-3" number. That is the more transparent choice: the two fatty acids have different biology and different claim conditions, and the authorised heart claim depends on their combined total. Splitting them out lets you add them up yourself and see exactly where a product sits against the 250 mg threshold ^².

Intake context and sensible use

General guidance frames omega-3 intake around oily fish — roughly one to two portions a week, delivering in the region of 250 mg EPA+DHA daily on average ^¹². WellsparQ's marine oils are modest, declared contributions to that total. On safety, EFSA has reviewed supplemental long-chain omega-3s and found no concern at commonly used intakes ^³; very high doses can affect bleeding time, so those on anticoagulants, awaiting surgery, pregnant or breastfeeding should take advice. Krill and fish oils are unsuitable for anyone avoiding animal or marine ingredients, and krill carries a crustacean-allergen warning ^¹.
