Dr. Sandra Kaufman frames medicine in three tiers: reactive Western medicine, diagnostic-heavy functional medicine, and proactive longevity medicine which targets cellular deceleration. This model redefines proactive health.
Dr. Kaufman simplifies the overwhelming complexity of cellular aging by organizing it into seven distinct categories, or "tenets." This framework makes it possible to strategically target different aspects of aging, from DNA repair to waste management.
Dr. Kaufman developed a unique rating system for supplements. Each of the seven digits corresponds to a "tenet of aging," and is rated 0-3 based on the strength of scientific evidence, providing a strategic, evidence-based approach to supplementation.
After age 40, NAD deficiency impacts three critical cellular functions: it starves mitochondria of energy, impairs sirtuins that regulate homeostasis, and hinders PARPs responsible for DNA repair, increasing cancer risk.
Dr. Kaufman visualizes a longevity strategy as a pyramid. The base is daily actions like diet, exercise, and supplements. Higher tiers include weekly massages and quarterly advanced treatments like exosome infusions, creating a structured, multi-layered approach.
Your family's medical history offers clues to which cellular aging processes are most vulnerable. A history of diabetes points to glycation issues (Tenet 7), while various cancers suggest weak DNA repair (Tenet 4), enabling a personalized anti-aging focus.
Dr. Kaufman explains the harmful process of glycation with a simple analogy: think of glucose as a sticky lollipop. It attaches to vital molecules like proteins and DNA, causing them to malfunction and leading to inflammation and aging.
Dr. Kaufman challenges the popular longevity practice of hyperbaric oxygen therapy. She argues that high oxygen levels create an abundance of tissue-damaging free radicals, which could ultimately accelerate the aging process instead of slowing it down.
Metformin works partly by inhibiting mTOR, a pathway essential for muscle protein synthesis. Taking it close to a workout can cancel out the benefits. Dr. Kaufman advises an eight-hour gap between taking Metformin and exercising to preserve muscle gains.
People over 40 often struggle with sleep, but it's not a willpower issue. The cellular machinery—specific proteins and pathways controlled by NAD and sirtuins—that regulates sleep deteriorates. These pathways can be targeted and fixed, restoring natural sleep.
Contrary to supplement labels advising morning intake, scientific models show that the body's natural NAD peak occurs in the afternoon. To best replicate this biological rhythm, NAD supplements should be taken around "British tea time."
Dr. Kaufman uses a powerful analogy to explain how spermidine works at a cellular level. The long, linear molecule embeds itself in the grooves of your DNA, physically shielding it from damage like "bubble wrap," protecting against oxidative stress and glycation.
