Frequently asked questions
Can you explain how it works?
plus

Lucis is simple. You start by booking a blood test at one of our partner labs. Once your results are ready, we turn them into a clear, personalized report — no medical jargon. From there, you receive actionable recommendations across nutrition, sleep, and lifestyle. Everything is tracked in your private dashboard, so you can see your progress over time and adjust as needed. No prescriptions, no waiting rooms, and no confusing PDFs.


Is my data secure and confidential?
plus

We take the confidentiality of your health data very seriously. We respond to the highest security standards with our encrypted platform, HDS certified, and GDPR compliant. Health data is strictly confidential and shared exclusively between you and the medical team.


When does my subscription begin?
plus

Your subscription begins immediately after purchase. You'll receive instructions to schedule your first blood test within 24 hours of signing up.


Why isn't this prescribed by my doctor?
plus

Traditional medicine primarily focuses on diagnosing declared diseases, not on health optimization or prevention. As long as there are no severe symptoms, a general practitioner will not prescribe this type of analysis because health insurance does not cover these tests without obvious symptoms or strong suspicion of disease. Lucis offers direct access to in-depth analysis, without waiting to be sick.


Why these biomarkers?
plus

Most traditional check-ups are limited to a few very basic indicators (cholesterol, blood sugar...). At Lucis, we analyze between 60 and 80 (advanced pack) biomarkers, because by looking at all your hormonal, inflammatory, metabolic, and nutritional parameters, we can detect imbalances well before the onset of diseases.
