Omega-3 Dosage: How Much EPA and DHA Do I Need Per Day?

How much omega-3 per day is actually sensible — and how much is too much? This is a question many people ask when they want to start supplementing or improve their omega-3 index. In this article you will find all the relevant dosage figures summarised and explained clearly, so you can make a well-informed decision.

EFSA Health Claims — the official minimum doses

In its evaluation of nutrition and health claims (Scientific Opinion 2012), EFSA defined specific minimum amounts of EPA and DHA at which health effects have been demonstrated. These so-called Health Claims are the legal basis for all product statements in the EU — and at the same time the best reference points for your personal dosage.

250 mg EPA+DHA for heart, brain and eyes

The lowest but universally valid recommendation is: 250 mg EPA+DHA daily. According to EFSA, this amount is sufficient to maintain the following functions:

• Normal cardiac function (EPA+DHA combined)
• Normal brain function (DHA alone: 250 mg)
• Normal vision (DHA alone: 250 mg)

Important: EFSA refers here to maintenance functions — not therapeutic effects. 250 mg is the lower threshold for basic supply, not the optimal dose for every purpose.

According to a review in Prostaglandins, Leukotrienes and Essential Fatty Acids (PMID 21951360), the actual average intake of EPA+DHA in Europe is clearly below this threshold — which explains why many people have a suboptimal omega-3 index.

3,000 mg EPA+DHA for blood pressure

For the blood pressure-lowering effect a considerably higher dose is necessary. EFSA sets the minimum amount for the Health Claim on supporting normal blood pressure at 3,000 mg EPA+DHA daily. This amount is difficult to achieve through normal diet alone — even with daily fish consumption. Those who wish to use omega-3 for blood pressure control therefore depend on high-dose supplements, ideally in consultation with their doctor.

2,000 mg EPA+DHA to reduce triglycerides

Raised triglyceride levels are an independent cardiovascular risk factor. EFSA confirms that 2,000 mg EPA+DHA daily contribute to the maintenance of normal triglyceride concentrations in the blood. Clinical studies show that therapeutic doses of 3,000–4,000 mg can even produce a measurable reduction in elevated triglyceride levels — more details in the article Lowering triglycerides with omega-3.

200 mg DHA for brain and eye development (foetus, infant)

For pregnant and breastfeeding women there is a special Health Claim: in addition to the general recommendation of 250 mg EPA+DHA, the mother should consume an additional 200 mg DHA daily. This provides 450 mg DHA+EPA, which according to EFSA is necessary to support normal brain and eye development in the child. DHA is the decisive fatty acid here: it makes up a considerable proportion of brain matter and the retina, and is incorporated particularly intensively into the foetal brain during the last months of pregnancy.

Comparison with other recommendations

Leading nutrition societies in Europe, such as the German Nutrition Society (DGE), have also formulated recommendations for long-chain omega-3 fatty acids that largely align with EFSA guidelines, although they sometimes place different emphases.

General population: 250 mg EPA+DHA per day

For adults, a daily intake of at least 250 mg EPA+DHA is recommended. Emphasis is placed on the fact that regular consumption of oily sea fish (salmon, herring, mackerel, sardines) — at least one to two portions per week — should be the preferred source.

Those who do not eat fish or dislike the smell can meet this requirement through fish oil or algae oil capsules.

Pregnant and breastfeeding women: 200 mg extra DHA

In line with EFSA, pregnant and breastfeeding women are recommended to increase their DHA intake by 200 mg daily. In practice, if during pregnancy you cannot or do not wish to eat oily fish every day, a DHA supplement — ideally from algae oil, which directly delivers DHA — is a sensible and safe alternative.

Foetal brain/eye development	200 mg extra DHA	DHA	In addition to 250 mg EPA+DHA

Dosage by health goal

The EFSA minimum doses provide a legally underpinned reference, but do not cover all scenarios. Clinical studies and meta-analyses show that for certain health goals, higher doses are sensible or necessary. The following overview summarises current study recommendations — not as a medical prescription, but as a guide for informed decisions.

Basic supply and heart protection (250–500 mg)

For general health maintenance and cardiovascular prevention, 250–500 mg EPA+DHA daily are sufficient. This amount corresponds to approximately two portions of oily fish per week or one standard capsule containing 500 mg fish oil. Studies show that even this low dose can significantly reduce the risk of sudden cardiac death. The buying guide helps you properly assess the quality of fish oil products.

Inflammation and joint pain (1,000–3,000 mg)

In inflammatory conditions such as rheumatoid arthritis, arthritis or chronic inflammatory processes, studies typically use 1,000–3,000 mg EPA+DHA daily. EPA is the more important fatty acid here, as it acts as a precursor of anti-inflammatory eicosanoids. A 2012 meta-analysis showed that doses from 2,700 mg EPA+DHA daily can significantly reduce morning stiffness in rheumatoid arthritis. In sport, many athletes use similar doses to support recovery — more details in the article Omega-3 for athletes.

Mental health (1,000–2,000 mg EPA-focused)

For support with depression and mood disorders, research shows a clear picture: EPA is more effective than DHA. Meta-analyses recommend products with an EPA:DHA ratio of at least 2:1 at a dose of 1,000–2,000 mg EPA daily. Pure EPA concentrates (such as Vascepa/icosapentaenoic acid) have even been used in clinical studies at doses of 4,000 mg EPA daily — though under medical supervision.

Lowering triglycerides (2,000–4,000 mg)

For a clinically relevant reduction of elevated triglyceride levels, doses of 2,000–4,000 mg EPA+DHA daily are necessary. The EFSA Health Claim begins at 2,000 mg. Clinical studies with prescription omega-3 supplements such as Lovaza or Vascepa use 3,360–4,000 mg daily and achieve triglyceride reductions of 20–30%. These dosages should always be undertaken in consultation with a doctor.

Blood pressure (3,000 mg)

The blood pressure-lowering effect of omega-3 commences according to EFSA from 3,000 mg EPA+DHA daily. A 2014 meta-analysis with more than 70 randomised controlled trials confirmed that this dose measurably reduces both systolic and diastolic blood pressure — particularly in persons with already elevated baseline values. More details in the article Omega-3 for blood pressure.

Mental health / Mood (EPA-focused)	1,000–2,000 mg EPA/day	Depression reviews (EPA > DHA)
Lowering triglycerides	2,000–4,000 mg/day	EFSA Health Claim, Lovaza studies
Blood pressure	3,000 mg/day	EFSA Health Claim, meta-analysis 2014

Special population groups

The optimal omega-3 dose is not a universal figure — it also depends on life stage, body weight and individual risk factors. Here are the most important groups with their specific recommendations.

Pregnant and breastfeeding women

Pregnancy and breastfeeding are the life stages with the highest DHA requirement. The unborn child and infant cannot synthesise sufficient DHA themselves — they are entirely dependent on the mother's supply. At least 200 mg extra DHA is recommended in addition to the general 250 mg EPA+DHA, i.e. a total of at least 450 mg daily.

Algae oil is the preferred source here, as it delivers DHA directly, is free from heavy metals and is suitable for vegans. More details in the article Omega-3 in pregnancy and in the article Omega-3 for pregnant women.

Children and adolescents

No specific EFSA Health Claims exist for children. Paediatric societies, however, recommend a daily DHA intake based on body weight: approximately 10–15 mg DHA per kg body weight. For a 25 kg child, this corresponds to approximately 250–375 mg DHA daily. In practice, a specialist children's fish oil supplement or regular fish consumption is usually sufficient. For dosage in children, the omega-3 calculator is also useful.

Older adults

With increasing age, omega-3 requirements potentially increase — both for muscle maintenance and cognitive health. Several studies show that older people benefit from doses between 1,000 and 2,000 mg EPA+DHA daily, particularly for the prevention of muscle loss (sarcopenia) and for memory support. At the same time, older adults taking blood thinners should discuss their dosage with their doctor (see warning box below). A comprehensive overview of optimal omega-3 supply in old age can be found in the article Omega-3 for older adults.

Vegans and vegetarians

Those who do not eat fish consume almost no EPA and DHA through food. ALA from linseed, chia seeds or walnuts is converted only inefficiently in the body — the conversion rate is below 10%.

Vegans should therefore pay particular attention to adequate supplementation: algae oil capsules deliver EPA and DHA directly. The dosage recommendations correspond to the general values, although 500–1,000 mg daily is often more sensible for vegans than the minimum dose. All details in the article Omega-3 for vegans.

How to calculate the dose from food and capsules

Many people underestimate how difficult it is to obtain sufficient EPA and DHA from food alone. The following overview shows the actual content values.

Reading labels correctly

With fish oil and algae oil supplements, a common mistake is to confuse the total amount of fish oil with the EPA+DHA content. A typical fish oil contains approximately 30% EPA+DHA — a capsule containing 1,000 mg fish oil therefore delivers only about 300 mg EPA+DHA. High-concentrate products (e.g. 70%+ concentration) deliver significantly more active ingredient from the same capsule size.

When buying, look for the explicitly stated EPA and DHA content in milligrams per serving — not the total fish oil amount. More details in the buying guide for omega-3 supplements.

It is also worth looking at the EPA to DHA ratio — depending on the health goal, a different ratio is optimal. All practical intake tips can be found in the article How to take omega-3 correctly.
