Getting checked when symptoms present is very important, and I hope to highlight that with my story.    Episode Sponsors: ProBio: probionutrition.com/endurance Code: Endurance (20% Off) LMNT: drinkLMNT.com/HPO (free sample pack with purchase) deltaG: deltagketones.com Code: BITTER20 (20% Off) True Nutrition: truenutrition.com/hpo Code: HPO (20% Off)   Podcast Details: Support HPO: zachbitter.com/hposponsors HPO Website: zachbitter.com/hpo  Zach's Coaching: zachbitter.com/coaching Zach's Journal: substack.com/@zachbitter Find Zach: zachbitter.com | IG: @zachbitter | X: @zbitter | FB: Zach Bitter | Strava: Zach Bitter
