Methodology
Biohack’s longevity score is derived from nutrient density (30+ tracked nutrients), established longevity biomarkers, and the body of research above — spanning fasting physiology, caloric restriction, micronutrient status, the gut microbiome, and metabolic health. Every scoring input is traceable to a cited source; nothing is a black box.
