Electrolytes Explained | Hydration, Performance & the Science Behind the Hype

💧 Are electrolytes essential for everyone... or have they become one of the most over-marketed products in nutrition?

Electrolytes are far more than ingredients in colorful sports drinks. These charged minerals power every heartbeat, muscle contraction, nerve impulse, and fluid shift in your body. But while they're essential for life, not everyone needs electrolyte supplements every day.

In this episode of the Longevity series, we explore the science behind electrolytes, how they regulate hydration, support athletic performance, maintain heart rhythm, and keep your body's electrical systems functioning. We'll also examine when electrolyte replacement is beneficial, when plain water is enough, and how marketing has blurred the line between genuine need and consumer hype.

Whether you're an athlete, weekend exerciser, or simply trying to stay healthy, this evidence-based guide will help you understand when electrolytes matter and how to use them wisely.
