Omega 3, 6 & 9: What’s the Difference, and What’s the Best Way to Take Them? (Backed by Science)

We hear about Omega 3, 6, and 9 all the time — but what are they really, and do we need all three? Are supplements like Omega 3-6-9 capsules actually worth it? And how do you know you’re buying a high-quality, organic product that’s truly beneficial?

Let’s clear the confusion with a science-backed look at these essential fatty acids and how best to get them.


✅ What Are Omega 3, 6 & 9?

These are types of unsaturated fats, known for their health benefits — especially when consumed in the right balance.

  • Omega 3 (essential) – Supports brain, heart, eye, and joint health. Found in fatty fish, flaxseed, chia seeds, and algae.
  • Omega 6 (essential) – Supports skin health and energy, but most people get too much through processed foods and vegetable oils.
  • Omega 9 (non-essential) – Still beneficial! Helps reduce inflammation and improve heart health. Found in olive oil and nuts.

⚖️ Why Omega 3 Is the Priority

Most people in the UK consume way too much Omega 6 (thanks to processed foods), and not enough Omega 3 — which is linked to inflammation, poor heart health, and even low mood.

🧠 Omega 3 is especially crucial for brain development, cognitive function, and mental wellbeing.

That’s why nutritionists often recommend supplementing Omega 3 on its own — or choosing an Omega 3-6-9 blend that prioritises the right balance (usually 2:1:1).


✅ Best Sources of Omega 3

Top food sources:

  • Fatty fish: salmon, sardines, mackerel (rich in EPA & DHA)
  • Chia seeds and flaxseeds: high in ALA (a plant-based form of Omega 3)
  • Algae oil: best vegan source of DHA — found in high-quality supplements

💊 Should You Take Omega 3, or 3-6-9?

Omega 3 alone is often the most effective and targeted supplement — especially if your diet already includes Omega 6 and 9 (which it likely does).

However, some people prefer an Omega 3-6-9 blend, which includes:

  • Flaxseed oil (plant-based)
  • Fish oil (or algae oil for vegans)
  • Borage oil (rich in GLA, a beneficial Omega 6)

Just make sure it uses cold-pressed, organic oils, and is free from heavy metals and rancidity.


🔍 What to Look For in a High-Quality Supplement

When shopping for an Omega supplement, especially online, check for:

  • Organic certification
  • Cold-pressed oils (not heat-treated)
  • No artificial additives
  • High EPA & DHA content (if fish-based)
  • Sustainably sourced (especially algae and fish oils)

⚠️ Avoid cheap capsules that don’t list exact EPA/DHA amounts or use the vague term “fish oil blend.”
