Biomarkers included

• Monounsaturated fatty acids: Monounsaturated fatty acids (MUFAs) are a type of healthy fat primarily found in plant-based oils, nuts, seeds, and avocados. Defined by a single double bond in their structure, MUFAs support heart health, help manage cholesterol levels, and are considered a beneficial component of a balanced diet.
• Palmitoleic acid (PLA): Palmitoleic acid is a monounsaturated fatty acid that plays a role in metabolism and overall health. Though less common than other fatty acids, it is found in sources like macadamia nuts and certain fish. It is gaining attention for its potential benefits on insulin sensitivity and cholesterol regulation.
• Stearic acid (SA): Stearic acid (SA) is a saturated fatty acid, a type of lipid, commonly found in many foods. It's a component of cell membranes and an essential building block for other fatty acids in the body. While high intake of some saturated fats is linked to cardiovascular risk, stearic acid's effect on cholesterol levels is often considered neutral or even slightly beneficial, as it can be converted to olei
• Oleic acid (OA): Oleic acid (OA) is a monounsaturated fatty acid that is the most abundant fatty acid in the human diet and adipose tissue. It is a key component of cell membranes and an important source of energy, playing a role in metabolic processes and cellular signaling. Elevated levels of oleic acid can sometimes be associated with certain metabolic conditions.
• Omega-6 / Omega-3 Ratio: The Omega-6 / Omega-3 Ratio compares the levels of pro-inflammatory omega-6 fatty acids to anti-inflammatory omega-3 fatty acids in the body. A high ratio indicates a diet rich in omega-6s, promoting inflammation, while a balanced ratio (closer to 1:1, or 4:1 as a conservative target) is desirable for cellular health and reducing chronic disease risk.
• Arachidonic acid (AA): Arachidonic acid (AA) is a polyunsaturated omega-6 fatty acid found in cell membranes and is an important substrate in immune and inflammatory signaling. It is a precursor to eicosanoids—bioactive molecules that help regulate processes such as inflammation, vascular tone, platelet aggregation (blood clotting), and pain and fever responses. AA is essential for normal physiology, but its effects dep
• Polyunsaturated Omega-3 fatty acids: Polyunsaturated Omega-3 (PUFA ω-3) fatty acids are essential nutrients that support overall human health. They are particularly found in fish, seeds, and nuts and play a key role in brain function, cardiovascular health, and neurological development.
• Docosapentaenoic acid (DPA): Docosapentaenoic acid (DPA) is a long-chain omega-3 fatty acid that plays an important role in supporting health, though it is less well-known than eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Found mainly in fish and seafood, DPA supports cardiovascular function, brain health, and overall well-being.
• Eicosapentaenoic acid (EPA): EPA is a long-chain omega-3 fatty acid found mainly in fatty fish and certain algae. It is incorporated into cell membranes and serves as a precursor to signaling molecules that help regulate inflammation, blood vessel function, and platelet activity. EPA status is often assessed as part of a fatty acid profile and is discussed in relation to cardiovascular health and inflammatory balance. Measure
• Gamma-linolenic acid (GLA): Gamma-linolenic acid (GLA) is an omega-6 fatty acid found in certain plant oils, such as evening primrose and borage oil. In the body, GLA can be converted into dihomo-gamma-linolenic acid (DGLA), which serves as a precursor to signaling molecules (prostaglandins/eicosanoids) involved in inflammatory regulation and immune-related pathways. Measured GLA levels can provide insight into omega-6 fatty
• Myristic Acid (MA): Myristic acid (C14:0) is a saturated fatty acid with a 14-carbon chain, found in animal fats, dairy products, and certain plant oils. It is involved in various biological functions but is also known to raise cholesterol levels when consumed in excess.
• Docosahexaenoic acid (DHA): DHA is a long-chain omega-3 fatty acid and a major structural component of cell membranes, particularly in the brain and retina. It supports normal brain development and function and contributes to visual health. The body can produce only small amounts of DHA from shorter-chain omega-3s, so DHA is primarily obtained through diet (for example, fatty fish and algae) or supplements. Adequate DHA stat
• Linoleic acid (LA): Linoleic acid (LA) is an essential omega-6 polyunsaturated fatty acid, meaning the body cannot produce it and it must be obtained through diet. It serves as a precursor for other important fatty acids like arachidonic acid and plays a vital role in maintaining skin barrier function, cardiovascular health, and immune responses. Monitoring LA levels can provide insights into dietary fat intake and t
• Dihomo-gamma-linolenic acid (DGLA): DGLA is a polyunsaturated omega-6 fatty acid formed in the body from linoleic acid (LA) via gamma-linolenic acid (GLA). It can be converted into signaling molecules (eicosanoids) that are generally considered less pro-inflammatory, and it may compete with arachidonic acid (AA) in inflammatory pathways. For this reason, DGLA is often discussed in relation to inflammatory balance and cell membrane f
• Omega-3 Index: The Omega-3 Index is a measure of the percentage of EPA and DHA (the most beneficial omega-3 fatty acids) in red blood cell membranes. It reflects long-term dietary intake of omega-3s and is considered a strong predictor of cardiovascular health risk. A higher Omega-3 Index is associated with a lower risk of heart disease.
• Palmitic acid (PA): Palmitic acid (PA) is the most common saturated fatty acid in animals and plants, serving as a primary component of fats and oils. It is a key building block for more complex lipids and plays a vital role in energy storage and cellular structure. Elevated or significantly altered levels of palmitic acid can be associated with metabolic disorders, cardiovascular disease risk, and insulin resistance
• Saturated Fatty Acids: Saturated fatty acids are a type of dietary fat commonly found in animal products and certain plant oils. They contain no double bonds in their structure, which makes them solid at room temperature. Their impact on health is multifaceted, with effects that can be beneficial or harmful depending on overall intake and dietary context.
• Polyunsaturated Omega-6 fatty acids: Polyunsaturated Omega-6 fatty acids are essential fats that support brain function, growth, and development. Found in plant oils, nuts, and seeds, they contribute to cellular health, help regulate inflammation, and promote cardiovascular well-being.
• Alpha-linolenic acid (ALA): Alpha-linolenic acid (ALA) is an essential omega-3 fatty acid, meaning the body cannot produce it and it must be obtained through diet. ALA can be converted into longer-chain omega-3 fatty acids such as EPA and DHA, although this conversion is limited in many individuals. Omega-3 fatty acids are involved in normal cell membrane function and play roles in cardiovascular, brain, and inflammatory pat

How to prepare

You take the test on an empty stomach in the morning. You can take supplements, but your results will reflect your levels while using them. If you want to measure your baseline levels without supplements, avoid omega-3 supplements for at least 3–7 days before testing (or 2–4 weeks for a more accurate baseline).

Frequently asked questions

How does it work? / When do I get my results?

1. Order and receive your kit. 2. Perform the test. 3. Send a sample at the beginning of the week (to avoid delays). 4. Results digitally in 10–15 business days.

What is a healthy Omega-3 Index?

The Omega-3 Index measures the percentage of EPA and DHA in your red blood cell membranes. A level of 8% or higher is typically associated with the best heart health, while levels below 4% are considered low.

Why is the Omega-6 to Omega-3 ratio important?

While Omega-6 is essential, an overabundance, found in many processed vegetable oils, can promote inflammation if not balanced by enough Omega-3. This test helps identify if your ratio is within a healthy range to manage inflammation.
