Our Focus
Four pillars of proactive care

Alzheimer's Prevention
ReCODE 2.0 protocols to identify and address cognitive decline risk factors decades before symptoms.
Longevity & Healthspan
Advanced biomarker panels, VO₂ max, body composition, and personalized protocols to extend healthy years.
Functional Women's Health
Annual exams, pregnancy planning, fertility, gut, sleep, and stress — through a root-cause lens.

The Prévant Health Difference
Early matters.
Most medicine waits for disease. We don't. Prévant means to prevent — and everything we do is designed to catch drift before it becomes diagnosis. Because the choices you make in your 30s, 40s, and 50s decide the person you get to be in your 80s and 90s.
