The Gut Performance MD Podcast

Nurse KC and Dr. Beth unpack how creatine affects muscle water and why hydration starts in the gut. They explain absorption through the small intestine, the role of sodium‑glucose transport in fluid uptake, and how body water is split between intracellular and extracellular compartments.
Creatine can increase intracellular muscle water but doesn’t replace fluids, electrolytes, or blood volume lost through sweat. The episode clarifies that creatine is part of a broader hydration conversation, not a full substitute for proper rehydration strategies.

Dr. Beth and Nurse KC break down pediatric hydration — why children are more vulnerable, how dehydration often shows up as behavior changes, and when plain water isn’t enough. Learn practical signs to watch for, sodium guidance for sports, and simple strategies to keep kids hydrated and performing their best.

Spring dehydration is sneaky—temperature swings, increased outdoor activity, allergies, caffeine, and alcohol change your fluid needs before summer arrives. In this episode Nurse KCand Dr. Beth explain why spring is the perfect time to start intentional hydration, introduce the new "Hydration Crimes of Spring" segment, and walk through common pitfalls (golfing, youth sports sidelines, festivals, gardening) where people quietly drift into dehydration.
They recommend practical steps: use the GPMD drop system to build a habit now, monitor urine color and symptoms, replace electrolytes as needed, and adapt hydration to changing activity and weather so you can “hydrate to dominate” into summer.

Dr. Beth and Nurse KC break down hydration confusion and explain two main intestinal transport pathways: glucose-sodium (SGLT1) and amino acid/peptide-assisted routes (including PEPT1).
They compare efficiency, use cases, and where sugar-free, amino acid-based products fit in the Gut Performance MD drop system, offering practical guidance on choosing the right hydration strategy for different needs.

Dr. Beth and KC introduce the Drops System, a simple, physiology-based way to plan hydration. Learn to hydrate intentionally with three tiers—Flow (baseline), Activate (faster absorption), and Perform (replacement for sweat)—so your body actually uses the fluids you drink.Start your plan each morning, pace intake throughout the day, and tailor drops to your activity and environment. This episode turns hydration from guesswork into an individualized, practical routine.

Hydration Confusion breaks down why “drink more water” is incomplete and explains the difference between maintenance hydration and rehydration after sweat, illness, or endurance activity.The episode covers oral rehydration solutions (ORS), the SGLT1 sodium–glucose transport pathway, sugar-free alternatives like amino acid co-transport, and practical guidance on choosing the right hydration strategy for your situation.

In this episode Nurse KC and Dr. Beth explain why even a 2% body-weight loss impairs power and focus, how plasma volume and environment (heat, altitude, cold) change hydration needs, and why salt is critical for fast fluid absorption.
They review product options for different intensities (LMNT and PRECISION HYDRATION 1500.) Hydration for ultra-high sodium; Liquid IV and Skratch Labs for performance all-rounders; tailwind or Flow for combined fuel and electrolytes) and give a practical elite protocol: prehydrate 0.1 oz per lb 2–4 hours before, replace 16–24 oz per lb lost after exercise, and if recovery time is under 12 hours aim for 24 oz per lb with a high-sodium snack or drink.

Dr. Beth, the Gut Performance MD, breaks down desert-festival hydration: why water alone can fail, the role of sodium, potassium, and glucose, and practical steps to stay energized through long sets.Learn the preload routine, the one-to-one rule for alcohol/caffeine, micro-sipping limits, hydrating foods, red flags for heat emergencies, and why electrolyte packets and a hydration pack are festival essentials.

In this episode we explore the high-stakes world of D1 vaulting and how precise hydration transforms power, timing, and nerve for split-second performances.Dr. Beth from Gut Performance MD explains why targeted carbohydrate-electrolyte mixes—especially sodium—matter, how to time drinks (three hours out, a primer 20 minutes before warm-ups, and sipping between rotations), and how to avoid a sloshy stomach while keeping your nervous system sharp.Practical tips include using professional-grade mixes, treating hydration like a prescription, and checking morning urine color to start meets well-hydrated.

Dr. Beth explains why sugar-free hydration drinks are useful for everyday activity but not always the best choice during intense or prolonged training. She describes how small amounts of carbohydrate improve fluid and sodium absorption and emphasizes individualized hydration strategies based on sport, intensity, duration, climate, and metabolism.
