Omega 3-6-9: What the Label Can and Can't Say
Omega-3 is one of the few supplement areas where the science is genuinely well established — but the label wording is tightly controlled, and the numbers on the back of the pack matter more than the claims on the front. Here is what omega 3-6-9 actually is, which part does the heavy lifting, and how to read a label properly.
Omega 3, 6 and 9 — what's the difference?
These are all types of fatty acid, and the numbers refer to their chemical structure.
- Omega-3 is the one most people are short on. The key forms are EPA and DHA (found in oily fish) and ALA (found in plants like flaxseed).
- Omega-6 is widespread in everyday foods like vegetable oils, nuts and seeds — most people already get plenty.
- Omega-9 is found in olive oil and many foods, and your body can also make it. Shortfalls are uncommon.
So while “omega 3-6-9” sounds like three things you are missing, in practice it is really the omega-3 portion — specifically EPA and DHA — that most people are interested in topping up.
What omega-3 is authorised to claim — and the doses behind it
This is the part worth understanding, because it is where honest products and overblown ones part ways. Health claims in Great Britain are controlled by the GB Nutrition and Health Claims Register, and the omega-3 claims only apply when a daily serving actually provides enough EPA or DHA:
- The heart-related claim requires 250mg of EPA and DHA a day.
- The brain and vision claims each require 250mg of DHA a day.
The key phrase in the register is “with a daily intake of”. A product can only stand behind those roles if it genuinely delivers those amounts at the recommended serving — which is exactly why you should read the EPA and DHA figures on the label rather than trust the marketing on the front. If a pack does not state its EPA and DHA per serving, treat that as a gap, not a detail.
What to look for in an omega supplement
| What to look for | Why it matters |
|---|---|
| EPA and DHA amounts, not just “fish oil” | The total oil weight tells you little; the EPA and DHA figures are what count against the 250mg guidance. |
| The source | Fish oil and krill oil supply EPA and DHA directly; flaxseed supplies ALA, which the body converts only modestly. |
| Freshness and form | Quality oils are handled to limit oxidation; a strong rancid smell is a bad sign. |
| Added vitamin E | Vitamin E contributes to the protection of cells from oxidative stress and also helps protect the oil itself. |
| Made to a recognised standard | GMP-certified manufacturing and clear UK labelling signal quality control. |
Where activGen Omega 3-6-9 fits in
Our Omega 3-6-9 Oils – with Vitamin E brings together oils from fish, flaxseed and sunflower, with added vitamin E, at 1000mg per capsule. It is GMP certified and made in the UK, and at £7.99 it is one of the more accessible ways into the category. It is designed as a simple, everyday essential-fats top-up across the omega family — not a concentrated EPA/DHA product, and we don't sell it on a heart or brain claim. If EPA and DHA specifically are your priority, a dedicated marine oil is the better route: our Krill Oil Omega-3 delivers EPA and DHA from Antarctic krill. Either way, check the EPA and DHA figures on the label against the 250mg guidance above and decide what fits your routine.

Frequently asked questions
Do I need omega 6 and 9 in a supplement?
Usually not — most people get ample omega-6 and omega-9 from everyday foods. The omega-3 portion (EPA and DHA) is the part most people are genuinely looking to top up.
Is plant-based omega-3 as good as fish oil?
Plant sources like flaxseed provide ALA, which the body can convert to EPA and DHA — but only to a limited degree. If EPA and DHA are your focus, a fish or krill source provides them directly.
How much EPA and DHA should I look for?
The authorised heart claim is based on 250mg of EPA and DHA a day, and the brain and vision claims on 250mg of DHA a day. Check the label to see how a serving compares — and remember a triple-oil “3-6-9” blend is not the same as a concentrated EPA/DHA fish or krill oil.
When should I take it?
Omega oils are fat-soluble, so many people take them with a meal. Pick a time you will remember consistently.
