The three biomarkers measured in our longevity assessment are:

1. Homocysteine An amino acid whose elevation (> 9 µmol/L) increases cardiovascular, bone, and neurodegenerative risk.
2. Omega-3 Index (EPA + DHA) Percentage of EPA and DHA fatty acids incorporated into red blood cell membranes; an index ≥ 8% is associated with better cardiac and cognitive health.
3. suPAR (soluble urokinase Plasminogen Activator Receptor) A marker of chronic inflammation and “biological aging”; high values predict cardio-metabolic diseases, renal failure, and all-cause mortality.

Homocysteine is a transient amino acid produced by protein metabolism. Because it can become toxic to blood vessels and the brain, the body works to keep it at a very low level: ideally < 9 µmol/L. To eliminate it, the body recycles homocysteine using vitamins B12, B6, and folic acid (B9), which transform it into useful compounds.

When this recycling process malfunctions, homocysteine accumulates in the blood. Numerous studies have linked this increase to:

• an increased cardiovascular risk (atherosclerosis, stroke, heart attack);
• a possible involvement in cognitive decline and Alzheimer’s disease.

Controlling homocysteine levels and ensuring an adequate intake of B vitamins is therefore essential for cardiovascular and brain health and longevity.

Proper brain function depends on two factors: a high Omega-3 Index (especially DHA) and low homocysteine levels. Vitamins B9, B12, and B6 are essential for effectively incorporating DHA into neuron membranes. When homocysteine levels rise, it accelerates tau protein aggregation and disrupts this integration of DHA, thereby promoting the brain atrophy observed in Alzheimer’s disease. Several studies show that supplementing with DHA and B vitamins—thereby reducing homocysteine—can slow cognitive decline, preserve neuronal structure, and, in turn, prolong healthy longevity.

• Increase your omega-3 intake: aim for two servings of oily fish (wild salmon, mackerel, sardines) per week and sprinkle your salads with chia seeds, flax seeds, or walnuts. If your intake is insufficient, supplement with 1 to 2 g/day of DHA + EPA (fish oil, krill oil, or algae oil).
• Get plenty of B vitamins (B6, B9, B12): green vegetables (spinach, kale), legumes, citrus fruits, whole grains, eggs, and organ meats. These vitamins recycle homocysteine and keep it below 9 µmol/L.
• Targeted supplementation: if your test results reveal a deficiency, take a B complex (400 µg folic acid + 1,000 µg B12 + 10–25 mg B6). Combine it with your omega-3s to maximize the incorporation of DHA into neuronal membranes.
• Anti-inflammatory lifestyle: regular physical activity, stress management, sufficient sleep, and limiting alcohol consumption reinforce nutritional effectiveness and further lower homocysteine levels.

A registered nurse collects the blood sample in accordance with current hygiene standards. The sample is then transported to an accredited laboratory for analysis.

The tests are carried out in a certified laboratory. The medical report is sent within 7 days of the sample being taken (working days).

The service is available in major Swiss cities. A travel surcharge may apply for outlying or remote areas.
