GPMD Podcast—Hot Take Summer 2026: Why a Stick Pack Isn’t a Hydration Plan

Summer 2026 is poised to be unusually hot, and this episode explains how heat changes physiology—sweat, sodium loss, blood flow shifts, and gut tolerance—and why one-off hydration packets don’t automatically meet your needs. Learn to choose hydration by purpose (daily maintenance, sweat replacement, heat/performance, illness, kids, or older adults), understand why mixing ratios and ingredients matter, and why pediatric and oral rehydration solutions differ from trendy stick packs. This episode breaks down Liquid IV as an example of different formulations for different jobs, emphasizes age and medical context, and offers practical, gut-smart tips: pick the job first, the formula second, and the flavor last.

GPMD Podcast— How Do You Hydrate Your Brain?

In this episode Nurse KC and Dr. Beth explain how brain hydration depends on stable blood flow, sodium balance, osmolality, and cell volume — and why the gut is essential because it absorbs the fluids and electrolytes that enter circulation. They cover common dehydration symptoms, why drinking more water isn't always the answer, and practical takeaways: balance fluids and electrolytes, consider gut absorption, and seek medical care for severe or new neurological symptoms.

GPMD Podcast— Dr. Beth Gets Real With Her Listeners!

Dr. Beth cuts through the overwhelm of wellness trends and marketing to deliver a simple, science-first approach to hydration, gut health, and performance. Learn why slowing down, asking better questions, and personalizing your plan matters more than chasing every new product.

GPMD Podcast— Creatine for Hydration?

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.

GPMD Podcast- Hydrate to Dominate, the Kids Edition

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.
