Bitter taste genetics explain why one client happily eats Brussels sprouts while another can’t get past the first bite. Learn how TAS2R38 variants create “super tasters” and “non-tasters,” why bitter receptors in the gut and lungs influence fullness and immunity, and the simple kitchen strategies that help every taste type eat more vegetables.
Walking genetics starts with an evolutionary blueprint: humans were built to cover 7–10 miles a day, yet most of us now walk about 1.5. Dr. Sam Shay, DC, FMCP, and Mikayla Wachsmann, MS, CNS, explain how regular walking lowers resting inflammatory markers like IL-6, TNF-alpha, and CRP, where step-count benefits really start and plateau, and the small habits practitioners can prescribe to close the gap.
Oxygen genetics determine how efficiently a client’s body takes in, transports, and uses oxygen to fuel their mitochondria — and that efficiency is one of the strongest predictors of longevity. Dr. Sam Shay breaks down four genes (AMPD1, VEGFA, HIF1A, and ACSL1) so practitioners know exactly which lever to pull when a client’s VO2 max stalls.
Recovery genetics — including VDR, IL-6, and TNF-alpha — shape how a client’s body responds to exercise-induced inflammation, injury risk, and how much recovery time is truly needed. Dr. Sam Shay breaks down how to tell whether training is building strength or just feeding chronic inflammation.
Speed gene: how ACTN3’s RR, XX, and RX genotypes reveal a client’s built-in edge for power or endurance—and where their injury risk really lies.
Collagen genetics — specifically COL1A1 and COL5A1 — shape how a client’s connective tissue handles load, hypermobility, and injury risk. Dr. Sam Shay breaks down what practitioners need to know to train, supplement, and recover hypermobile clients safely.
