Why this score
Gary Brecka is a self-described human biologist, biohacker, and co-founder of 10X Health System, with over 20 years of experience in health and wellness. His background stems from the insurance industry, where he worked as a mortality-modeling expert analyzing medical data to predict life expectancies down to the month, which inspired his shift to optimizing longevity through biomarkers, blood chemistry, and personalized nutrition protocols. He lacks formal medical credentials such as MD or PhD and has faced criticism for promoting unverified health claims without a medical license, yet he is popular among celebrities like UFC president Dana White for his biohacking approaches to aging, performance, and disease prevention.
