What omega 3-6-9 actually means
Omega 3-6-9 supplements line the shelves of every sports nutrition store. But what do those three numbers actually mean — and do you need all of them?
Short answer: omega-3 is essential, you're probably getting more than enough omega-6 already, and omega-9 your body makes itself. Here's the full picture.
The numbers refer to the position of the first double bond from the methyl end of the carbon chain:
- Omega-3 (n-3): ALA (plant oils), EPA and DHA (oily fish, algae)
- Omega-6 (n-6): LA (sunflower and soybean oils), AA (animal fats)
- Omega-9 (n-9): oleic acid (olive oil, avocado) — not essential, because the body synthesises it from saturated fats
EPA vs DHA: roles and differences
Of all omega-3 fatty acids, EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) matter most for health. ALA, found in flaxseed and chia, converts to EPA and DHA in the body — but at very low rates, typically under 10% of ALA intake.
EPA is primarily anti-inflammatory: it is the precursor for eicosanoids that regulate immune response and vascular function. DHA is a structural component of the brain and retina.
EFSA (European Food Safety Authority) concluded in 2010 that a combined EPA and DHA intake of 250 mg per day contributes to normal cardiac function. For active people, the International Society of Sports Nutrition (ISSN) points toward at least 1–2 g EPA + DHA daily. Studies examining clinically meaningful effects on triglycerides and inflammation typically use 2–4 g EPA + DHA per day (Calder, 2017).
The n-3/n-6 ratio: what it actually means
The modern Western diet carries an estimated omega-6 to omega-3 ratio of 15–20:1. Historically it was closer to 4:1. Both families compete for the same COX and LOX enzymes, so a large omega-6 surplus blunts the anti-inflammatory effects of EPA and DHA.
But the problem isn't that you're getting too little omega-6 — it's that you're getting too little omega-3. The fix is to increase EPA and DHA intake, not to aggressively restrict omega-6.
Do you need supplemental omega-6? Almost certainly not. Sunflower oil, soybean oil and nuts cover the requirement with ease. Omega-6 deficiency in typical Estonian or Northern European diets is extremely rare.
Fish oil vs krill oil vs algae omega-3
| Source | EPA + DHA content | Form | Notes |
|---|---|---|---|
| Fish oil | High (up to 60–70% in concentrate capsules) | Triglyceride or ethyl ester | Cheapest, most researched |
| Krill oil | Lower per capsule | Phospholipid | Phospholipid form may have better bioavailability; evidence is limited |
| Algae omega-3 | Moderate | Triglyceride | Vegan-friendly; clean EPA and DHA source |
For bio omega 3 6 9 blends — such as ICONFIT Softgel Omega 3-6-9 N90, which combines fish oil with linseed and olive oil — the combination is not harmful, but check that the EPA + DHA fraction is meaningful (at least 300–500 mg per capsule). The omega-6 and omega-9 fractions in these blends add minimal value if your diet already covers those bases.
For pure fish oil, OstroVit Omega 3 Ultra 90 caps and OstroVit Omega 3 150 Capsules are straightforward options available at maxfit.ee. Møllers omega 3 6 9 is a well-known Nordic brand; quality fish oil brands publish IFOS-certified batch test results.
Dosage guidelines (EFSA, ISSN)
- General health maintenance: 250–500 mg EPA + DHA per day (EFSA, 2010)
- Sports and training recovery: 1–3 g EPA + DHA per day
- Triglyceride reduction: 2–4 g per day under medical supervision
- Pregnancy: at least 200 mg DHA per day above the usual intake (EFSA recommendation)
Take fish oil capsules with a fat-containing meal — this meaningfully improves absorption.
Quality indicators: oxidation, TOTOX and IFOS
Rancidity is fish oil's biggest quality problem. Oxidised oil not only tastes unpleasant — it may be harmful. Key markers:
- Peroxide value (PV): < 5 mEq/kg (GOED standard)
- Anisidine value (AV): < 20
- TOTOX (2 × PV + AV): < 26
- IFOS certification: independent third-party batch testing
Choose products packaged in dark bottles, with a certificate of analysis (COA) available, and at least 12 months until expiry.
Nordic diet context
Traditional Estonian and Nordic diets include Baltic herring, salmon and other oily fish — genuinely good omega-3 sources. If you eat oily fish at least twice a week, your supplementation need may be lower. If not, a fish oil supplement is a reasonable and cost-effective step.

Bottom line: do you actually need all three?
- Omega-3 (EPA + DHA): likely yes, if you don't eat oily fish regularly
- Omega-6: no — diet covers this more than adequately
- Omega-9: no — your body synthesises it
Combined omega 3-6-9 capsules are not harmful, but plain fish oil is usually a simpler and cheaper way to get sufficient EPA and DHA.

FAQ
Do you actually need supplemental omega-6 or omega-9?
For most people in Estonia and Northern Europe: no. Omega-6 (mainly linoleic acid) is abundant in vegetable oils and nuts, and deficiency is essentially unknown in typical diets. Omega-9 (oleic acid) is synthesised by the body and also plentiful in olive oil, avocado and most nuts. Supplementing either alongside omega-3 adds little practical benefit.
What is TOTOX and why does it matter?
TOTOX is a composite measure of fish oil oxidation (2 × peroxide value + anisidine value). Lower is better; the acceptable ceiling is below 26. High TOTOX indicates a rancid product — the health benefits of oxidised fish oil are diminished and it may cause oxidative stress.
Fish oil vs krill oil: which is better?
Both are well-sourced EPA and DHA. Krill oil's phospholipid form may absorb slightly more readily, but the evidence is not conclusive and krill capsules contain less EPA + DHA in absolute terms. Fish oil is cheaper, better studied and an excellent choice for most people.
