Compare omega-3 products by the declared daily amount of EPA, DHA or ALA—not simply the milligrams of oil on the front. Capsules are pre-portioned; liquid oil must be measured. Fish and algae oils can provide EPA and DHA directly, while flax oil provides ALA. Choose by source, labelled serving, allergens, warnings and preferred format, not the largest number.
For shoppers in the UK, United States, Canada and other international markets, availability, delivery and import conditions vary by destination. Check the current product page and checkout before ordering the exact item.
Why “1,000 mg oil” does not mean “1,000 mg EPA + DHA”
The oil amount is the total carrier oil. The useful comparison is the separately declared omega-3 amount and its type. EPA and DHA are long-chain omega-3s. ALA is an essential plant omega-3, but the body converts only a limited amount into EPA and DHA. Therefore 500 mg ALA is not equivalent to 500 mg EPA + DHA.
Four exact products compared
| Product | Source and format | Labelled serving | What to compare |
|---|---|---|---|
| Mivolis Omega-3 1000 fish-oil capsules | fish oil; 1–2 capsules daily | at least 260 mg EPA + DHA per capsule | fish allergen, gelatin, flexible serving |
| Mivolis Omega-3 algae-oil capsules | algae oil; 1 daily, 2 for increased need; 1 during pregnancy/breastfeeding | 265 mg EPA + DHA per capsule | vegan; pregnancy/breastfeeding limit |
| Mivolis Omega-3 flax-oil capsules | flax oil; 1 capsule daily | ALA from flax oil; no direct EPA/DHA dose declared | ALA is not the same as EPA/DHA |
| Doppelherz system Omega-3 liquid family | liquid fish oil; 15 ml (ages 4–7) or 30 ml (7+ and adults) | 161 mg omega-3 per 15 ml or 322 mg per 30 ml; 250 mg DHA per 30 ml | contains fish, sugar and added vitamins; age-based serving |
Fish-oil capsules: pre-portioned EPA and DHA

Flax-oil capsules: ALA rather than direct EPA/DHA
Mivolis Omega-3 Leinöl 1000 Kapseln, 30 St, 47 g · GTIN 4066447656794. Vegan flax-oil food supplement. It provides ALA, so it is not the same product type as direct EPA/DHA from fish or algae.

A practical selection framework
1. Decide whether you want directly declared EPA/DHA or plant ALA. 2. Compare the daily serving, not oil weight or capsule count alone. 3. Choose fish or vegan and check allergens. 4. Choose a pre-portioned capsule or measured liquid. 5. Check age limits, pregnancy guidance, added vitamins and the delivered pack. These are alternatives, not a combination recommendation.
Safety and important cautions
All four are food supplements, not medicines, and do not treat or prevent disease. Never exceed the label or combine several omega-3 products without professional guidance. Seek medical or pharmacy advice for pregnancy, breastfeeding, children, chronic illness, surgery or medicines—especially anticoagulants. Supplements do not replace a varied diet and healthy lifestyle.
Frequently asked questions
Is 1,000 mg oil the same as 1,000 mg omega-3?
No. Oil weight includes all components. Compare the separately declared EPA, DHA or ALA.
Is algae oil the same as fish oil?
Both can provide direct EPA and DHA, but source, formulation, allergens and dose differ.
Does flax oil directly replace EPA and DHA?
Not automatically. Flax oil provides ALA, and conversion to EPA and DHA is limited.
Which product suits children or pregnancy?
Only one whose exact label applies. The liquid has age-based servings from 4 years; the algae product limits pregnancy and breastfeeding to 1 capsule. Seek advice when unsure.
