Omega-6 / omega-3 ratio: normal range and what your result means

What is the Omega-6 / Omega-3 Ratio?

It measures the balance between omega 3 and omega 6 ratio, two essential fatty acids that play key roles in cellular function, metabolic health, and overall wellbeing.

Why does it matter for long-term health and wellbeing?

A balanced ratio supports healthy inflammation levels, cognitive function, skin health, and general metabolic balance. It gives you a clearer picture of how your dietary fat intake is shaping long-term vitality.

What’s an optimal level of the Omega-6 / Omega-3 Ratio?

• Optimal range: 1 to 2
• Lab reference range: 1.9 to 14.6

Levels within the optimal range suggest a supportive balance of essential fats.

What influences Omega-6 / Omega-3 Ratio levels?

Food choices (especially oily fish, nuts, seeds, and ultra-processed foods) have the strongest effect. Supplements and individual absorption differences also play a role.

What does it mean if the Omega-6 / Omega-3 Ratio is outside the optimal range?

A higher ratio often reflects low Omega-3 intake, high Omega-6 intake, or both. This provides a useful prompt to reassess nutritional balance.

How can I support healthy Omega-6 / Omega-3 levels?

Increase Omega-3-rich foods (such as salmon, sardines, or algae-based options), reduce ultra-processed foods, and prioritise whole-food eating patterns.
