OmegaCheck Panel

Essential fats that reveal the balance between inflammation and health across the heart, brain, and immune system.

About

This panel measures the levels and balance of key fatty acids in your blood, providing a detailed view of how your diet and metabolism may influence inflammation, heart health, brain function, and overall well-being. It includes the OmegaCheck, a highly validated test for analyzing omega-3 fatty acid status.

Omega-3 fatty acids, such as EPA, DHA, and DPA, are critical for reducing inflammation and supporting heart, brain, and immune health.

  • Eicosapentaenoic Acid (EPA) helps regulate the body’s inflammatory response and protects heart and vascular health.
  • Docosahexaenoic Acid (DHA) is especially important for the brain, eyes, and nervous system. DHA supports cognitive function and development across the lifespan.
  • Docosapentaenoic Acid (DPA) serves as a metabolic bridge between EPA and DHA, with emerging research showing benefits for cardiovascular health and immune balance.

Omega-6 fatty acids, such as arachidonic acid (AA) and linoleic acid (LA), are also essential. They are involved in regulating inflammation, building cell membranes, and supporting brain and immune functions.

  • Arachidonic Acid (AA) can fuel inflammation if not balanced properly with omega-3s.
  • Linoleic Acid (LA), found in many vegetable oils, is a major dietary omega-6 that becomes part of cell membranes and can influence inflammation depending on the overall fatty acid balance.

The Omega-6:Omega-3 ratio is a powerful marker of dietary fat quality and inflammation risk. A lower ratio (more omega-3 relative to omega-6) is generally linked with better cardiovascular, cognitive, and inflammatory health outcomes. Modern Western diets often skew heavily toward omega-6s, contributing to a higher ratio and a higher risk of chronic diseases.

The Arachidonic Acid:EPA (AA:EPA) ratio provides another lens into inflammation control. Higher AA relative to EPA can suggest a greater tendency toward chronic inflammation, which is linked to heart disease, autoimmune conditions, and other health problems. Ideally, this ratio should be kept low through diet or targeted supplementation.

In a healthy state, the body maintains a dynamic balance between omega-6 and omega-3 fatty acids, fine-tuning inflammation as needed for healing without allowing it to become chronically harmful. These biomarkers offer critical insight beyond standard cholesterol tests, especially when conventional markers seem normal yet subtle signs of inflammation or poor dietary fat intake are present.

8 Biomarkers Included

OmegaCheck
The concentration of EPA, DPA, and DHA omega-3 fatty acids in whole blood that support heart, brain, and inflammation health.
Omega-6:Omega-3
The ratio of omega-6 to omega-3 fatty acids—an important marker of inflammation and dietary fat quality.
Arachidonic Acid:EPA
The ratio of arachidonic acid to EPA—a marker of inflammation and dietary fat quality.
Eicosapentaenoic Acid
An omega-3 fatty acid primarily involved in regulating inflammation and supporting heart and vascular health.
Docosahexaenoic Acid
An omega-3 fatty acid essential for brain, eye, and nervous system health—especially important for cognitive function and development.
Docosapentaenoic Acid
An intermediate omega-3 between EPA and DHA, with emerging roles in cardiovascular and immune function.
Arachidonic Acid
A key omega-6 fatty acid that helps regulate inflammation, immunity, and brain function—best understood in balance with omega-3s
Linoleic Acid
A major dietary omega-6 fatty acid involved in cell membranes and inflammation—can reflect dietary fat intake and metabolism.
