Founded by experts in aging and biometric data from Harvard, MIT and Tufts, InsideTracker puts data at the center of its programs, designed to help people eat better, live longer and better understand their bodies. This is exemplified in InsideTracker's Ultimate Plan, which tracks 43 total biomarkers to give an individual a complete picture of everything from metabolism and endurance, to oxygen levels and bone and muscle composition. This information is then incorporated into a personalized plan that targets fitness goals and overall well-being. Speaking of personalization, InsideTracker's InnerAge 2.0 program tackles personalized nutrition in a revolutionary way; using a data-led model to calculate an individual's "biological age," InsideTracker will work directly with clients to shape a suite of science-backed recommendations to help improve and extend longevity and lifestyle quality.
