Part 3 of 3 - Sandra Kaufman: NAD explained by a world expert—facts vs fiction, and what works

WHO IS SANDRA KAUFAN, MD? Dr. Sandra Kaufman is a physician and longevity scientist known for translating complex cellular aging science into practical, personalized health optimization strategies. Trained as an anesthesiologist with over two decades of clinical experience, she also has a background in cell biology—giving her a rare blend of real-world medicine and deep bench-science thinking. She’s the author of The Kaufman Protocol: Why We Age and How to Stop It, where she introduces a structured longevity framework designed to move beyond generic “take these supplements” advice. Her work focuses on how and why cells decline over time, and how to intervene with evidence-based therapies—organized into what she calls the “Seven Tenets of Aging.” A key feature of her approach is a scoring/rating system that evaluates therapies by the strength of evidence (from theory and lab data to animal models and human outcomes), helping clinicians and patients build a longevity plan that’s more algorithmic and less guesswork.
