A note from the founder
“Longevity is a science. It deserves the same rigor, humility, and precision we bring to any other branch of medicine.”
— Dr. Ari Sahebkashaf, MD
Dr. Ari Sahebkashaf, MD is a physician working at the intersection of lifestyle medicine, preventive care, and longevity science. He founded The Longevity Lab MD — an editorial platform that translates peer-reviewed longevity research into practical, evidence-based guidance for living longer, healthier, and sharper.
The Longevity Lab MD publishes physician-authored deep dives on exercise science, metabolic health, sleep, nutrition, biomarkers, cognition, and preventive medicine — alongside a curated daily brief on the AI, biotech, and clinical research shaping the field.
Dr. Ari’s work is guided by a single principle: longevity is not lifestyle content. It is medicine — and it deserves to be practiced with the rigor of the discipline it belongs to.
