"I am a strong advocate for the power of biomarker testing in optimizing health and longevity. It is a cornerstone of my practice. By providing a detailed, personalized snapshot of an individual’s biological functions, biomarker testing allows us to move beyond generalized advice and focus on what really matters for each person’s unique needs. We need to move to an era of "n of 1" medicine, and Function helps us empower that transition. I believe in the power of biomarker testing to empower people to take control of their health with science-backed, actionable data." -Dr. Darshan Shah
