OmegaCheck:
One of the Most Actionable
Longevity Panels We Run

There are a handful of lab panels that meaningfully change the way we think about long term health risk and are actionable with benefits that can begin almost immediately. OmegaCheck is one of them.

It is strongly tied to cardiovascular, metabolic, inflammatory, and cognitive health, and unlike many longevity markers that feel abstract or genetically predetermined, fatty acid balance is often something we can improve relatively quickly through nutrition and targeted supplementation.

And importantly, it gives us information that standard cholesterol panels completely miss.

What is OmegaCheck?

OmegaCheck is an advanced fatty acid panel that evaluates the balance of omega-3 and omega-6 fatty acids in the blood.

Together, these markers help us evaluate inflammatory balance, membrane composition, and long term cardiometabolic patterns in a much deeper way than a standard lipid panel alone.

Because while traditional cholesterol testing tells us how fats are being transported through the bloodstream, OmegaCheck helps us understand something different: what your cells are actually being built from.

Why omega fatty acids matter so much

Your cell membranes are not passive structures. They influence how cells communicate, how inflammation is regulated, how insulin signaling functions, how mitochondria perform, and even how flexible and resilient tissues remain over time.

The fats incorporated into those membranes matter enormously.

Omega-3 fatty acids, particularly EPA and DHA, tend to support a more balanced inflammatory environment and healthier membrane function. This is one reason omega balance has become such an important focus in longevity medicine.

EPA, DHA, and DPA: the omega-3s most associated with healthy aging

OmegaCheck evaluates three major omega-3 fatty acids, each with distinct physiologic roles.

EPA

EPA plays a major role in inflammatory regulation and cardiovascular health. Higher EPA levels have been associated with healthier triglyceride levels, lower inflammatory signaling, and improved cardiovascular outcomes. This is one reason some patients notice relatively rapid improvements in markers like triglycerides after increasing omega-3 intake.

DHA

DHA is one of the most structurally important fats in the human body. It is heavily concentrated in the brain, the retina, and neuronal membranes. DHA plays major roles in cognition, membrane fluidity, visual function, and neurologic health. The brain is one of the most omega-dependent organs in the body.

DPA

DPA sits metabolically between EPA and DHA, but it is not simply a passive intermediary. It appears to have its own biologic effects, particularly within the vascular system. Some research suggests DPA may help support endothelial function, reduce platelet aggregation, and participate in inflammatory regulation in ways distinct from both EPA and DHA. Certain populations with high marine food intake have disproportionately elevated DPA levels, leading some researchers to question whether part of the cardiovascular protection historically attributed broadly to omega-3s may partially involve DPA specifically. The evidence base for DPA remains thinner than for EPA and DHA and should be interpreted accordingly.

Together, EPA, DHA, and DPA provide a much broader picture of omega-3 status and tissue incorporation over time than simply asking whether someone takes fish oil.

The omega-6 to omega-3 ratio matters too

Omega-6 fats are not inherently bad. We need them.

The issue is imbalance.

Modern dietary patterns have shifted fatty acid balance in a way that is fairly unprecedented from an evolutionary standpoint. For most of human history, omega-3 and omega-6 intake existed in relatively close balance. Today, many people consume omega-6 fatty acids continuously throughout the day through restaurant foods, packaged foods, dressings, sauces, fried foods, and processed snacks, while consuming almost no meaningful marine omega-3 intake at all.

The body uses omega-3 and omega-6 fats to generate different signaling molecules involved in inflammation, vascular tone, clotting, and immune activity. Over time, a chronically skewed ratio may contribute to a more inflammatory physiologic environment associated with cardiometabolic disease and accelerated aging trajectories.

A large prospective cohort study of 85,425 UK Biobank participants found that risk for all-cause mortality, cancer mortality, and cardiovascular mortality all increased as the plasma omega-6 to omega-3 ratio increased. A 2025 study published in Frontiers in Nutrition analyzing 183,230 UK Biobank participants found that adding the plasma omega-6 to omega-3 ratio to the standard SCORE2 cardiovascular risk model significantly improved prediction of major adverse cardiovascular events. And the mean omega-6 to omega-3 ratio of the standard American diet is approximately 10 to 1. Research suggests a ratio of 4 to 1 or less may reduce total mortality up to 70% over two years.

A disproportionately elevated omega-6 to omega-3 ratio may reflect:

1. low omega-3 intake
2. high ultra-processed food intake
3. poor overall dietary quality
4. a more inflammatory physiologic environment

The goal is not strict elimination. It is balance and awareness of patterns that accumulate quietly over time.

One of the most clinically useful markers: the AA to EPA ratio

One of the most interesting parts of OmegaCheck is the relationship between arachidonic acid and EPA.

Arachidonic acid is an omega-6 fatty acid involved in inflammatory signaling pathways. Inflammation itself is not bad. We need inflammation for immune defense and tissue repair. But persistent inflammatory signaling without appropriate resolution appears to contribute to many chronic diseases associated with aging.

The AA to EPA ratio helps provide insight into that balance. Research from Quest Diagnostics and the Cleveland Heart Lab validates the AA to EPA ratio as a predictor of cardiovascular risk, with a higher ratio associated with higher risk for major cardiac-related diseases and events. A lower ratio often reflects stronger omega-3 incorporation and better inflammatory regulation.

This can become particularly relevant in patients with:

1. elevated triglycerides
2. insulin resistance
3. cardiovascular risk factors
4. autoimmune conditions
5. chronic inflammatory symptoms
6. high processed food intake

One of the best parts: the information is highly actionable

This is what makes OmegaCheck such a valuable longevity tool. Many biomarkers feel difficult to meaningfully influence. Omega balance often is not.

For many patients, improving these markers involves relatively attainable interventions:

Many people begin improving inflammatory signaling and triglyceride metabolism relatively quickly, even before larger long term tissue incorporation changes fully occur. Retesting then allows us to objectively evaluate whether those interventions are actually changing physiology over time.

The bigger longevity picture

Longevity is not simply about living longer. It is about preserving cognitive function, cardiovascular resilience, metabolic flexibility, physical vitality, and quality of life over decades.

OmegaCheck gives us insight into one of the most foundational aspects of physiology: the inflammatory and structural environment of the body itself.

And often, some of the most meaningful longevity interventions are not the most extreme. They are the consistent, measurable physiologic shifts that quietly improve resilience year after year.
