#225: Doug Grant - The NBA's First Nutritionist on Microplastics, Digestive Enzymes, and TruShield™ Testing

Doug Grant is the founder and chief formulator of Optimal Health Systems (OHS), a whole-food supplement company he built from the ground up starting in 1990. By 1993, he’d become the first full-time nutritionist hired by an NBA franchise, starting with the Phoenix Suns and later serving the San Antonio Spurs and Miami Heat through seven championship seasons in a decade. In this episode, Doug covers three major areas: The enzyme cascade science behind his flagship digestive product The blood-work-first philosophy he’s built from more than two decades with professional athletes OHS’s developing work on microplastics (including a probiotic-derived enzyme and a blood-based plastic test that their independent chemist fully intended to disprove). We also get into DSHEA, in-house manufacturing, and why TruShieldâ„¢ Certified is the natural fit for a brand that was already doing third-party testing before anyone required it. TruShield’s origin story is told in our conversation with Lori Bestervelt, Ph.D., and Thane Campbell on Episode #193. Here, we get into why a company like Optimal Health Systems, who works with professional athletes, formulates the way they do, and why they need a service like TruShield Certified to ensure drug-free compliance. https://blog.priceplow.com/podcast/doug-grant-optimal-health-systems-225 Video: Doug Grant of Optimal Health Systems Explains Microplastics and More https://www.youtube.com/watch?v=1MSHRt328fs Detailed Show Notes with Doug Grant of Optimal Health Systems (0:00) – Doug Grant and the Road to the NBA (8:45) – The Enzyme Cascade Behind Digest-A-Meal (16:00) – How Processed Foods Are Breaking Us Down (19:45) – Foundation, Customization, and Intervention (27:00) – Blood Work Lessons from the NBA (33:45) – Why OHS Chose TruShieldâ„¢ Certified (42:15) – DSHEA, In-House Manufacturing, and the Three Criteria (47:00) – Tracking Microplastics Through the Blood (52:45) – ChemZyme, PlasticTest, and the Tupperware Case Study (1:03:00) – Data as the Foundation Where to Follow and Learn More Connect with Doug Grant LinkedIn: Douglas Grant Instagram: Douglas D Grant Optimal Health Systems Optimal Health Systems Website Instagram: @ohs4life LinkedIn: Optimal Health Systems Optimal Health Systems on PricePlow TruShieldâ„¢ Certified TruShieldâ„¢ Certified Website TruShieldâ„¢ Certified: WADA-Experienced Lab Launches Comprehensive Banned Substance Testing Program Episode #193: Banned Substances in Supplements?
