OmegaCheck Test

OmegaCheck is a blood test that measures your current levels of three essential omega-3 fatty acids: EPA (eicosapentaenoic acid), DPA (docosapentaenoic acid), and DHA (docosahexaenoic acid). These fats are termed “essential” because your body cannot synthesize them and must rely on dietary sources or supplements. By analyzing their concentrations in whole blood, OmegaCheck provides a real-time snapshot of your omega-3 status and recent intake.

Each omega-3 plays a unique yet complementary role in promoting health. EPA is well-known for its anti-inflammatory properties and cardiovascular support. DHA is crucial for brain structure and cognitive function, especially as we age. DPA, though less studied, appears to enhance both vascular health and inflammation resolution.

Omega-3s work in part by balancing the body’s inflammatory response. They compete with pro-inflammatory omega-6 fats like arachidonic acid and help generate “resolving” molecules that actively turn off inflammation when it’s no longer needed. This contributes to a range of benefits: lower blood triglycerides, improved blood pressure, reduced plaque formation in arteries, and better insulin sensitivity.

In the brain, DHA serves as a key structural component of neurons, maintaining flexible, responsive cell membranes. EPA helps suppress neuroinflammation, which is linked to mood disorders like depression. Emerging evidence suggests DPA may aid in brain repair and resilience, although more research is needed.

OmegaCheck can also reflect how well your body is coping with metabolic stress. Chronic, low-grade inflammation—common in conditions like type 2 diabetes and fatty liver disease—can often be traced to omega-3 deficiency. By directly measuring omega-3 levels, OmegaCheck gives insight into your body’s ability to resolve inflammation and maintain metabolic balance.

Preliminary research suggests higher omega-3 levels may also reduce the risk of certain cancers by lowering oxidative stress and chronic inflammation. While this connection is still under investigation, OmegaCheck provides a valuable window into your body’s inflammatory environment—a key driver of many chronic diseases.

Maintaining optimal omega-3 levels through diet or supplements is linked to longer lifespan and reduced risk of disease, especially cardiovascular disease—the world’s leading cause of death. OmegaCheck helps determine whether your current lifestyle is delivering enough of these vital fats to support long-term health.
