From the practice · Praxis Dr. Romanos
Omega-3 fatty acids are not just a nutrition trend — they are biologically essential. In my GP practice, I notice that many patients have a critical deficiency without knowing it. This has serious consequences for the heart, brain, and chronic inflammation.
Omega-3 fatty acids are polyunsaturated fats with three main types: EPA and DHA (marine sources) and ALA (plant sources). EPA and DHA are biologically most effective and concentrate in the brain, retina, and heart.
Omega-3 fatty acids reduce triglycerides, stabilise heart rhythm, and have anti-inflammatory effects. Studies consistently show that a high omega-3 index is associated with better heart outcomes. This is a central topic in my health check-up.
DHA is a major component of the brain. Low omega-3 status is associated with depression, anxiety, and cognitive disorders. I recommend that my patients check their omega-3 index and optimise it specifically.
The omega-3 index measures the percentage of EPA and DHA in red blood cells. An index above 8% is considered protective. In my practice, I test this routinely, especially in patients with cardiovascular risks or chronic inflammation.
Ideal sources are fatty fish (salmon, mackerel, sardines). But many patients eat too little fish or cannot consume enough for various reasons. In such cases, high-quality omega-3 supplements make sense — part of my approach in metabolic optimisation.
The therapeutic dose is 1-2g EPA/DHA daily. I regularly monitor my patients' status and adjust the dose to achieve optimal cardiovascular and neurological protective outcomes.
