The Gut Performance MD Podcast

Dr. Beth explains why the liver is the body’s master battery and recycling plant for athletes, and how a sluggish liver undermines recovery and performance.Learn four practical strategies—refuel with carbs + protein after training, hydrate to support detox and bile production, prioritize sleep for liver cleanup, and avoid alcohol/processed sugars—to keep your liver tuned for peak performance.

Dr. Beth explains how anti-diuretic hormone (ADH) controls hydration during runs by conserving water and responding to sodium, blood volume, and stress—meaning hydration isn't just about how much you drink.Key takeaways: avoid excessive plain water that can cause hyponatremia, replace fluids with electrolytes (and sometimes carbs) for better absorption, and tailor your hydration strategy to run length, sweat rate, and climate.

Dr. Beth Carter, a pediatric gastroenterologist and nutrition specialist, breaks down athletic hydration beyond just water. She explains the pros and cons of sodium chloride, sodium citrate, and Himalayan pink salt, focusing on GI tolerance, absorption speed, taste, and real-world performance effects.The episode recommends sodium citrate as the preferred option for intense exercise because it speeds gastric emptying, buffers metabolic acidosis, and is easier to drink for long efforts. Table salt is inexpensive but can cause gut distress and flavor fatigue, while Himalayan salt’s trace minerals are unlikely to help during competition.Key takeaways: personalize your hydration plan, test new mixes in training (never on race day), and prioritize gut-friendly electrolytes for peak performance.
