Omega-3 Index
Blood test measuring EPA+DHA in red blood cells. Optimal: >8%. Under 4% = high cardiovascular risk.
What is Omega-3 Index?
Omega-3 Index is a blood test that measures the levels of the essential fatty acids EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) in red blood cells. These fatty acids are important for the body's functions and have a significant impact on our health. An optimal Omega-3 Index is above 8%, while levels below 4% indicate a high cardiovascular risk. By understanding the Omega-3 Index, individuals can gain better insight into their overall health status and risk factors for cardiovascular diseases.
How does it work in the body?
The body cannot produce omega-3 fatty acids on its own, making it essential to obtain them through diet. EPA and DHA play important roles in the body's inflammation and immune response, as well as contributing to normal brain function and heart health. When we consume omega-3-rich foods or supplements, these fatty acids are transported to cell membranes where they contribute to the cells' structure and function. A high level of omega-3 in red blood cells is associated with reduced inflammation and improved cardiovascular health.
Scientific benefits
Research has shown that a high Omega-3 Index may have several health benefits:
- Healthy heart function: According to a study published in the Journal of the American College of Cardiology, a high omega-3 level can reduce the risk of cardiovascular diseases.
- Memory and cognitive function: Several studies have linked higher levels of DHA to improved cognitive function and reduced risk of dementia.
- Inflammation reduction: Omega-3 fatty acids have demonstrated anti-inflammatory effects, which may be beneficial for individuals with chronic inflammatory diseases.
It is important to note that these benefits are based on scientific studies and individual results may vary.
Dosage and recommendations
The exact dosage of omega-3 may vary depending on individual needs and health conditions. Generally recommended:
- For adults: 250-500 mg EPA and DHA per day for general health.
- For individuals with cardiovascular diseases: 1000 mg or more, depending on medical advice.
It is always important to consult a doctor before starting supplements, especially if you have underlying health issues or are taking other medications.
Best sources and forms
Omega-3 fatty acids can be obtained from both diet and supplements. Some of the best sources include:
- Fatty fish: Salmon, mackerel, herring, and sardines are rich in EPA and DHA.
- Supplements: Omega-3 supplements are available as fish oil, algal oil (for vegetarians), and krill oil.
- Plant sources: Flaxseed, chia seeds, and walnuts contain ALA (alpha-linolenic acid), which the body can partially convert to EPA and DHA, but in smaller amounts.
It is important to choose high-quality supplements to ensure purity and efficacy.
Side effects and warnings
Although omega-3 is generally safe to consume, some individuals may experience side effects such as:
- Gastrointestinal discomfort and nausea
- Bleeding, especially at higher doses
- Allergic reactions in people with fish or shellfish allergies
It is important to follow recommended dosages and consult a doctor with any questions or concerns.
Frequently asked questions
What is the optimal Omega-3 Index?
The optimal Omega-3 Index is above 8%. Levels below 4% may indicate a high cardiovascular risk.
Can I get enough omega-3 through diet?
Yes, by including fatty fish, nuts, and seeds in your diet, you can achieve recommended omega-3 levels.
Is it safe to take omega-3 supplements?
For most people, omega-3 supplements are safe, but it is always best to consult a doctor before starting new supplements.
How often should I test my Omega-3 Index?
It is recommended to test the Omega-3 Index annually or when there are changes in health status or diet.
Can omega-3 affect my weight?
Some research suggests that omega-3 may support weight loss and metabolic health, but it is not a miracle cure and should be combined with a balanced diet and exercise.

Omega-3
Omega-3 fatty acids are essential polyunsaturated fats that the body cannot produce itself. The main forms are EPA and DHA (from fish) and ALA (from plants). Omega-3 supports the heart, brain, and joints.
EPA
Eicosapentaenoic acid — an omega-3 fatty acid with potent anti-inflammatory effects. Supports heart and mental health.
DHA
Docosahexaenoic acid — an omega-3 fatty acid constituting 40% of the brain's fatty acids. Essential for cognition and vision.
