Omega 3: EPA, DHA, Food Sources and How Much You Need - Metabolics

Omega 3: EPA, DHA, Food Sources and How Much You Need

28 August 2026

Key points

 

In short: Omega-3 fatty acids are essential, meaning the body cannot make them and they must come from diet or supplements. There are three main types: EPA and DHA, found mainly in oily fish, and ALA from plant sources such as flaxseed. The body converts ALA to EPA and DHA only inefficiently, which is why the marine forms are treated separately. NHS guidance is to eat at least two portions of fish a week, one of them oily.

 

  • EPA and DHA: contribute to the normal function of the heart, with the beneficial effect obtained at a daily intake of 250mg of EPA and DHA combined.

 

  • DHA specifically: contributes to the maintenance of normal brain function and to the maintenance of normal vision, each at a daily intake of 250mg.

 

  • During pregnancy and breastfeeding: maternal intake of DHA contributes to the normal brain and eye development of the foetus and breastfed infants. The effect is obtained at 200mg of DHA daily in addition to the 250mg recommended for adults.

 

  • ALA: contributes to the maintenance of normal blood cholesterol levels, at a daily intake of 2g.

 

  • What to look for in a fish oil: the EPA and DHA figures rather than the total oil weight, the fish species used, whether the oil comes from flesh or liver, and whether batches are tested for oxidation.

 

  • Flesh versus liver oil: oils from fish flesh differ from liver oils such as cod liver oil, which also contain vitamin A. That matters in pregnancy, where high vitamin A intake is not advised.

 

  • Metabolics Omega 3 specifics: 1,000mg combined EPA and DHA per serving, extracted from anchovy, sardine and mackerel flesh, with added vitamin E and batch testing for oxidation.

 

  • How to take it: one to two soft gels daily with food, since omega-3 is fat-soluble and absorbs better alongside a meal.

 

  • Worth checking first: anyone taking anticoagulant medication should speak to their GP or pharmacist before starting a fish oil.

 

Omega 3 fatty acids are essential nutrients that play an important role in everyday wellness. Whether you’re looking to support a balanced lifestyle, maintain your dietary intake or add to your supplement routine, omega 3s can be a valuable part of the picture. In this article, we’ll explore what omega 3 is, how to choose a high-quality supplement and practical tips for including it in your diet

 

What is Omega 3?

 

Omega 3s are essential fatty acids that the body cannot produce on its own, they must be obtained through your diet or supplements. There are three main types:

 

EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) - commonly found in fish oil

 

ALA (alpha-linolenic acid) - found in plant-based sources such as flaxseed; however, the body converts ALA to EPA and DHA less efficiently.

 

Why You’ll Appreciate it!

 

  • Supports heart health

 

  • Contributes to normal brain function

 

  • Aids in inflammatory balance

 

  • Good for skin health

 

  • Nourish maternal health as part of your prenatal routine

 

Metabolics Omega 3 Highlights

  • High potency: 1,000 mg combined EPA & DHA per serving.

 

  • Includes added vitamin E to enhance stability and effectiveness

 

  • Each batch is tested for oxidation to ensure freshness and potency remain

How to use it?

 

Take 1-2 soft gels daily with food for best absorption. Choose a time that fits your daily routine - morning or evening.


What Customers Are Saying

 

“Excellent quality vitamins, was recommended by a friend, and not disappointed “

 

“Easy ordering and quick delivery. Product is tasteless and although a large capsule is easy to swallow. I purchased following recommendation to take from a kinesiology specialist due to nutrition requirement for eczema and joints, I have noticed a positive difference already for both from only taking for a short period”

 

“Great quality Omega 3 tablets with no after taste. I have been taking these for years and always buy from Metabolics due to the impeccable service and exceptional quality”
