Most Replayed Moment: Mouthwash REVERSES The Benefits Of Exercise! Dr Nathan Bryan

In this most replayed episode of The Diary Of A CEO, Dr. Nathan Bryan reveals a startling connection between everyday oral hygiene habits and systemic health. He explains that fluoride in toothpaste and antiseptic mouthwash destroy the oral microbiome, which is essential for producing nitric oxide—a molecule critical for cardiovascular health, exercise benefits, hormone regulation, and wound healing. Using data from clinical studies and historical context, Bryan argues that routine mouthwash use nullifies the cardioprotective effects of exercise, while sugar, antacids, and mouth breathing further impair nitric oxide production. He advocates for a holistic approach: eliminating fluoride and sugar, avoiding antacids, practicing nasal breathing and tongue scraping, and embracing sunlight and red light therapy to naturally boost nitric oxide. The episode underscores how small daily choices—like brushing with non-fluoridated toothpaste or stopping mouthwash—can have profound, life-altering health impacts.
