Omega-3 explained: ALA, EPA, DHA and daily intake
Omega-3 is a family of fats, not a single ingredient. ALA, EPA and DHA are related, but they are not interchangeable amounts on a label. Here is how to understand food sources, daily-intake guidance and the different 250 mg conditions without turning every meal into a calculation.
ALA, EPA and DHA in plain language
ALA is an essential fatty acid found in foods such as walnuts, flaxseed, chia and rapeseed oil. EPA and DHA occur in fish and seafood and can also be supplied directly by certain microalgae oils. The body can convert ALA to EPA and DHA, but conversion is limited and variable. This does not make ALA-containing foods unimportant; it means a gram of ALA is not a gram of EPA or DHA.
How much omega-3 do adults need?
EFSA set an adequate intake of 250 mg EPA+DHA per day for adults. This is a population nutrition reference, not a requirement for everyone to take a capsule or a treatment dose. The separate authorised brain and vision statements refer to 250 mg DHA per day. Do not confuse those different uses of the same number.
Food first, with room for a considered supplement
Oily fish can provide EPA and DHA alongside protein and other nutrients. The amount varies with species, portion and production conditions, so “a piece of fish” is not an exact dose. A plant-based diet can include ALA-rich foods; algae oil is an option when direct EPA or DHA is wanted without fish. Consider what you already eat before adding a product.
More is not automatically better
Research using gram-level or prescription omega-3 preparations does not tell you to take several extra food-supplement capsules. Trials in some people with cardiovascular disease or elevated risk have linked 4 g/day regimens to a higher risk of atrial fibrillation. Medical treatment of high triglycerides belongs with a clinician, not a self-selected high-dose routine.
Is an omega-3 blood test necessary?
An omega-3 index measures EPA and DHA in red blood cells. It is a status measurement, not a diagnosis of why you feel tired, have dry skin or struggle to concentrate. There is no single established diagnostic cut-off for all those symptoms. If symptoms persist, seek an assessment of their possible causes instead of using them to choose a dose.
The two BMPHARMA formulas, on the same basis
| Comparison | Omega 3 fish oil | Omega 3 Algae — life'sOMEGA |
|---|---|---|
| Recommended daily serving | 1 capsule | 2 capsules |
| EPA | 500 mg | 200 mg |
| DHA | 250 mg | 600 mg |
| EPA + DHA | 750 mg | 800 mg |

What the 250 mg figures actually mean
| Authorised nutrient statement | Daily intake for the beneficial effect |
|---|---|
| EPA and DHA contribute to the normal function of the heart | 250 mg EPA and DHA combined |
| DHA contributes to maintenance of normal brain function | 250 mg DHA |
| DHA contributes to the maintenance of normal vision | 250 mg DHA |
Both labelled servings above meet these three intake conditions. The brain and vision statements require 250 mg of DHA itself, not merely 250 mg of EPA and DHA added together. These are normal-function statements, not promises to prevent heart disease or improve memory beyond normal function.
Check suitability before taking either product
Both products are food supplements for adults. Their labels exclude children, pregnancy and breastfeeding. Do not use them if you are allergic to an ingredient, and do not exceed the labelled serving. Fish oil contains fish and bovine gelatin; a vegan label on an algae product is not a guarantee against every allergy. If you take medicines, particularly anticoagulants, have a heart-rhythm condition or are due for surgery, discuss supplementation with a doctor or pharmacist. Food supplements do not replace a varied diet and healthy lifestyle.
Frequently asked questions
Is 1000 mg fish oil the same as 1000 mg omega-3?
No. Oil weight includes more than EPA and DHA. Read the individual fatty-acid amounts and the serving size.
Do I need fish oil if I eat fish regularly?
Not automatically. A supplement is one way of adding EPA and DHA, not an obligatory companion to a balanced diet.
Can I choose algae oil during pregnancy?
DHA advice in pregnancy is a separate nutrition discussion. The two BMPHARMA products compared here are labelled as unsuitable during pregnancy and breastfeeding; do not override that warning because their oil source sounds suitable.
