Omega-3 fish oil: how to choose the strength and the EPA and DHA dose

Quick answer

Choose omega-3 by the sum of EPA and DHA in the daily serving, not by the 500 or 1000 mg in the name: the Stivits 500 mg and 1000 mg capsules with vitamin E both give 300 mg of EPA and DHA. Stivits has six variants of this food supplement, from 120 to 750 mg of EPA and DHA per capsule. EPA and DHA contribute to the normal function of the heart. The beneficial effect is obtained with a daily intake of 250 mg of EPA and DHA. One capsule of any variant except Super Omega 3-6-9 meets this condition. DHA contributes to maintenance of normal brain function. The beneficial effect is obtained with a daily intake of 250 mg of DHA: only Triple Strength Omega-3 Fish Oil gives this dose. A varied and balanced diet and a healthy lifestyle are important.

Stivits omega-3: a comparison by the numbers

The numbers are for the daily serving. Compare the column "EPA and DHA": the EU claims are tied to this sum.

On Russian-language packs EPA and DHA are sometimes printed as ЭПК and ДГК. They are the same acids.

What is omega-3 for?

Three EU register claims fit Stivits servings: the heart for the sum of EPA and DHA, and the brain and vision for DHA alone. All three apply only at the stated dose, so it sits next to each claim:

  • EPA and DHA contribute to the normal function of the heart. The beneficial effect is obtained with a daily intake of 250 mg of EPA and DHA.
  • DHA contributes to maintenance of normal brain function. The beneficial effect is obtained with a daily intake of 250 mg of DHA.
  • DHA contributes to the maintenance of normal vision. The beneficial effect is obtained with a daily intake of 250 mg of DHA.

A varied and balanced diet and a healthy lifestyle are important. Five of the six Stivits variants meet the heart claim; only one meets the claims on the brain and vision: Triple Strength Omega-3 Fish Oil, 250 mg of DHA per capsule.

What does 1000 mg in the name of omega-3 mean?

The 1000 mg in the name is the weight of the oil in the capsule, not of EPA and DHA. At Stivits, products with 1000 mg in the name contain very different amounts: from 120 mg of EPA and DHA in Super Omega 3-6-9 to 750 mg in triple strength. So compare the sum of EPA and DHA.

Product with 1000 mg in the name, per 1 capsuleEPA and DHA
Super Omega 3-6-9 1000 mg120 mg
Omega-3 Fish Oil 1000 mg + Vitamin E300 mg

Double Strength Omega-3 Fish Oil 1000 mg 330 EPA & 220 DHA550 mg
Triple Strength Omega-3 Fish Oil 1000 mg 500 EPA & 250 DHA750 mg

Fish oil 500 mg or 1000 mg: which to choose

Both give the same amount of EPA and DHA: 180 mg of EPA and 120 mg of DHA per capsule, 300 mg together. The difference is the concentration of the oil. In the 500 mg capsule the share of EPA and DHA is 60%, in the 1000 mg capsule 30%, so you get the same dose from half as much oil.

Vitamin E contributes to the protection of cells from oxidative stress. The trade-off is the same for both: to get 600 mg of EPA and DHA you need 2 capsules a day, and the pack runs out twice as fast.

Double or triple strength: which to choose

Double strength gives 330 mg of EPA and 220 mg of DHA per capsule, triple strength 500 mg of EPA and 250 mg of DHA. For both, 1 capsule a day with a meal is enough, and both meet the heart claim. Only triple strength meets the claims on the brain and vision.

Choose double strength if 550 mg of EPA and DHA is enough for you and you want a longer-lasting pack: 90 capsules last 90 days. Choose triple strength if you want 750 mg of EPA and DHA and 250 mg of DHA in one capsule. Trade-off: 60 capsules last 60 days.

“Double” and “triple” here are names, not multipliers: 550 mg and 750 mg against 300 mg in a standard capsule, roughly 1.8 and 2.5 times.

Omega-3 and vitamin D3: when to choose the capsule with D3 and K2

Omega-3 Fish Oil 1000 mg +D3 +K2 + Vitamin E suits you if you want omega-3 and vitamins in one capsule. It contains 550 mg of EPA and DHA, 50 µg (2000 IU) of vitamin D3, 50 µg of vitamin K2 as MK-7 and 12 mg α-TE of vitamin E. 60 capsules last 60 days.

  • Vitamin D contributes to the maintenance of normal bones.
  • Vitamin D contributes to the normal function of the immune system.
  • Vitamin K contributes to the maintenance of normal bones.
  • Vitamin E contributes to the protection of cells from oxidative stress.

Trade-off: if you already take Vitamin D3 4000 IU High Strength with Olive Oil, 100 µg, together with this capsule you get 150 µg, while the EFSA upper level for adults is 100 µg a day. In that case choose omega-3 without D3.

Omega 3-6-9 or omega-3

Super Omega 3-6-9 1000 mg is a blend of fish, linseed and sunflower oils. A capsule contains 135 mg of omega-3, 203 mg of omega-6, 120 mg of omega-9 and 6.6 mg α-TE of vitamin E. EPA and DHA total only 120 mg, below the threshold of 250 mg, so it has no heart claim.

Choose it if you want a blend of three oils. If it is EPA and DHA you need, the other Stivits variants give 2.5 to 6.25 times more: from 300 to 750 mg per capsule. Use Super Omega 3-6-9 within 3 months of opening the pack.

EPA and DHA: how they differ

EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) are two omega-3 fatty acids from fish oil. For the EU register the difference is this: the heart claim applies to their sum, the claims on the brain and vision to DHA only. So for the heart, look at the sum; for the brain and vision, at the DHA figure on its own.

Fish oil or plant-based omega-3

Linseed and other plant oils contain a different omega-3, ALA, while fish oil gives EPA and DHA. The body can synthesise EPA and DHA from ALA, but the register claims on the heart, brain and vision are tied to EPA and DHA themselves. All Stivits omega-3 with EPA and DHA is made from fish oil; the catalogue has no plant-based alternative.

How much omega-3 a day do you need?

EFSA considers 250 mg of EPA and DHA a day adequate for adults. In pregnancy and breastfeeding, 100–200 mg of DHA is added on top. EFSA has not set an upper level for EPA, DHA and DPA: there are not enough data. No NRV is set for EPA and DHA, so go by the dose in the claims and the serving of the product.

One capsule of any Stivits variant except Super Omega 3-6-9 provides 250 mg of EPA and DHA or more. Do not exceed the serving of the product.

Age, pregnancy and other food supplements

  • Fish allergy. This omega-3 is not for you: every variant contains fish oil.
  • A child aged 3 or over. According to Stivits data, Omega-3 500 mg + Vitamin E is suitable: 1 capsule a day.
  • A teenager aged 12 or over. Super Omega 3-6-9 is also suitable: 1 capsule a day.
  • Pregnancy and breastfeeding. Omega-3 500 mg + Vitamin E: 2 capsules a day, 240 mg of DHA. Omega-3 1000 mg + Vitamin E: 1–2 capsules a day.
  • You already take D3. Choose a variant without D3 or add up the doses.
  • You need 250 mg of DHA. Only triple strength gives it.
  • You are under a doctor's care. Consult your doctor about omega-3.

How to take fish oil

Take omega-3 with meals. Store the capsules in the original packaging, in a dry place, at room temperature and out of the reach of young children. Food supplements should not be used as a substitute for a varied and balanced diet.

FAQ

How do I choose omega-3?

Choose by the sum of EPA and DHA in the daily serving. At Stivits 1 capsule gives 300 mg in the 500 mg and 1000 mg variants with vitamin E, 550 mg in double strength and in the capsule with D3 and K2, 750 mg in triple strength.

Omega-3 dose: how many mg a day?

EFSA considers 250 mg of EPA and DHA a day adequate for adults. At Stivits 1 capsule of any variant meets this dose, except Super Omega 3-6-9, where EPA and DHA total 120 mg. Do not exceed the serving of the product.

What is omega-3 good for?

For Stivits servings the EU register has three claims. EPA and DHA contribute to the normal function of the heart; the beneficial effect is obtained with a daily intake of 250 mg of EPA and DHA. DHA contributes to maintenance of normal brain function. DHA contributes to the maintenance of normal vision. The beneficial effect of each is obtained with a daily intake of 250 mg of DHA. Five of the six Stivits variants meet the heart claim, only triple strength meets the brain and vision claims. A varied and balanced diet and a healthy lifestyle are important.

What should the composition of omega-3 be?

Look at the EPA and DHA lines and their sum in the daily serving, not at the weight of the fish oil. At Stivits one capsule has 300 mg of EPA and DHA in the 500 mg and 1000 mg variants with vitamin E, 550 mg in double strength and in the capsule with D3 and K2, 750 mg in triple strength. Only Super Omega 3-6-9 is below 250 mg, at 120 mg.

What does 1000 mg on an omega-3 pack mean?

It is the weight of the oil in the capsule, not of EPA and DHA. At Stivits, products with 1000 mg in the name range from 120 mg to 750 mg of EPA and DHA per capsule, so compare this sum.

How does fish oil 500 mg differ from 1000 mg?

They contain the same amount of EPA and DHA, 300 mg per Stivits capsule. The 500 mg capsule is more concentrated: 60% against 30%, vitamin E 5 mg against 3.3 mg, 180 capsules in the pack against 90.

Do I need triple strength?

You do if you want 250 mg of DHA in one capsule: only this Stivits variant meets the claims on the brain and vision. For the heart claim, 300 mg of EPA and DHA in a standard capsule or 550 mg in double strength is enough.

What is the difference between EPA and DHA?

Both acids are omega-3 from fish oil. The EU heart claim applies to their sum, and the claims on the brain and vision to DHA only. Stivits triple strength has 500 mg of EPA and 250 mg of DHA per capsule.

Can I take omega-3 and vitamin D3 together?

Yes, if you keep an eye on the total of D3. The Stivits capsule with D3 and K2 already contains 50 µg (2000 IU) of D3. The EFSA upper level for adults is 100 µg a day, so do not take it together with D3 4000 IU.

Omega 3-6-9 or omega-3: which should I choose?

If you need EPA and DHA, choose one of the five variants that are not a blend of oils. Super Omega 3-6-9 from Stivits has 120 mg of EPA and DHA per capsule, below the threshold of 250 mg for the heart claim. A standard Stivits capsule has 300 mg.

From what age can children take omega-3?

According to Stivits data, children aged 3 and over can take Omega-3 500 mg + Vitamin E, 1 capsule a day, which is 300 mg of EPA and DHA. Super Omega 3-6-9 suits ages 12 and over. The other variants are intended for adults.

Can I take omega-3 on an empty stomach?

Take it with a meal: that is what the directions say for all Stivits omega-3, usually 1 capsule a day. Link it to one meal and you are less likely to forget it.

How long should I take omega-3?

The directions for Stivits omega-3 give no length of course, only the daily serving: 1 capsule or 1–2 capsules. A pack lasts from 45 to 180 days, depending on the variant and the serving. Do not exceed the serving, and agree on long-term use with a doctor.

Can you overdose on omega-3?

EFSA has not set an upper level for EPA, DHA and DPA because the data are not sufficient. That is not permission to take more: the Stivits serving is 1 or 2 capsules a day, so do not exceed it. If you are under a doctor's care, agree on omega-3 with them.

Which omega-3 brand should I choose, and who makes Stivits omega-3?

Compare the sum of EPA and DHA in the daily serving, which is in the table above. Stivits is a brand of the Estonian company HYPERPHARM OÜ (Tallinn). The supplements are made in Europe, in the EU, in a factory certified to GMP, HACCP and ISO 22000:2018. Stivits sells direct from the factory, with no wholesalers or pharmacies in between.
